RESUMEN

PURPOSE: Despite the availability of clinical guidelines for hip fracture patients, adherence to these guidelines is challenging, potentially resulting in suboptimal patient care. The goal of this study was (1) to evaluate and benchmark the adherence to recently established quality indicators (QIs), and (2) to study clinical outcomes, in fragile hip fracture patients from different European countries. METHODS: This observational, cross-sectional multicenter study was performed in 10 hospitals from 9 European countries including data of 298 consecutive patients. RESULTS: A large variation both within and between hospitals were seen regarding adherence to the individual QIs. QIs with the lowest overall adherence rates were the administration of systemic steroids (5.4%) and tranexamic acid (20.1%). Indicators with the highest adherence rates (above 95%) were pre-operative (99.3%) and post-operative haemoglobin level assessment (100%). The overall median time to surgery was 22.6 h (range 15.7-42.5 h). The median LOS was 9.0 days (range 5.0-19.0 days). The most common complications were delirium (23.2%) and postsurgical constipation (25.2%). CONCLUSION: The present study shows large variation in the care for fragile patients with hip fractures indicating room for improvement. Therefore, hospitals should invest in benchmarking and knowledge-sharing. Large quality improvement initiatives with longitudinal follow up of both process and outcome indicators should be initiated.

RESUMEN

INTRODUCTION: Chronic pain is one of the most frequent clinical problems after inguinal hernia surgery. Despite more than two decades of research and numerous publications, no evidence exists to allow for chronic postoperative inguinal pain (CPIP) specific treatment algorithms. METHODS: This narrative review presents the current knowledge of the non-surgical management of CPIP and makes suggestions for daily practice. RESULTS: There is a paucity for high-level evidence of non-surgical options for CPIP. Different treatment options and algorithms have been published for chronic pain patients in the last decades. DISCUSSION AND CONCLUSION: It is suggested that non-surgical treatment is introduced in the management of all CPIP patients. The overall approach to interventions should be pragmatic, tiered and multi-interventional, starting with least invasive and only moving to more invasive procedures upon lack of effect. Evaluation should be multidisciplinary and should take place in specialized centres. We strongly suggest to follow general guidelines for treatment of persistent pain and to build a database allowing for establishing CPIP specific evidence for optimal analgesic treatments.

RESUMEN

Following knee and hip arthroplasty, transfer to a recovery area immediately following surgery and before going to ward might be unnecessary in low-risk patients. Avoiding the recovery area in this way could allow for more targeted use of resources for higher risk patients, which may improve operating theatre flow and productivity. A prospective single-centre cohort study on the safety of criteria for bypassing the post-anaesthesia care unit in elective hip and knee arthroplasty was designed. Criteria were: ASA physical status < 3; peri-operative bleeding < 500 ml; low postoperative discharge-score (modified Aldrete-score); and an uncomplicated surgical and neuraxial anaesthesia procedure. The primary outcome was the number of patients in need of secondary readmission to the post-anaesthesia care unit. Events within the first 24 postoperative hours were recorded, along with readmission and complication rates. A total of 696 patients were included, with 287 (41%) undergoing total hip arthroplasty, 274 (39%) undergoing total knee arthroplasty and 135 (19%) undergoing unicompartmental knee-arthroplasty. Of these, 207 (44%) bypassed the post-anaesthesia care unit. Patients all received multimodal analgesia without peripheral nerve blockade. Only one patient in the ward group required secondary readmission to the post-anaesthesia care unit. Within 24 h, 151 events were reported, with 41 (27%) in the ward group and 110 (73%) in the post-anaesthesia care unit group. Two events in each group occurred within 2 hours of surgery. No complications were attributed to bypassing the post-anaesthesia care unit. The use of simple pragmatic criteria for bypassing the post-anaesthesia care unit for patients undergoing knee and hip arthroplasty with spinal anaesthesia is possible and associated with significant reduction of post-anaesthesia care unit admission and without apparent safety issues. Confirmation is needed from other studies and external validity should be interpreted cautiously in centres with different peri-operative regimens, organisational and staffing structures.

RESUMEN

Objective assessment of fluid status in critical surgical care may help optimize perioperative fluid administration and prevent postoperative fluid retention. We evaluated the feasibility of hydration status and fluid distribution assessment by Bioimpedance spectroscopy Analysis (BIA) in patients undergoing acute high-risk abdominal (AHA) surgery. This observational study included 73 patients undergoing AHA surgery. During the observational period (0-120 h), we registered BIA calculated absolute fluid overload (AFO) and relative fluid overload (RFO), defined as AFO/extracellular water ratio, as well as cumulative fluid balance and weight. Based on RFO values, hydration status was classified into three categories: dehydrated (RFO < - 10%), normohydrated (- 10% ≤ RFO ≤ + 15%), overhydrated RFO > 15%. We performed a total of 365 BIA measurements. Preoperative overhydration was found in 16% of patients, increasing to 66% by postoperative day five. The changes in BIA measured AFO correlated with the cumulative fluid balance (r2 = 0.44, p < .001), and change in weight (r2 = 0.55, p < .0001). Perioperative overhydration measured with BIA was associated with worse outcome compared to patients with normo- or dehydration. We have demonstrated the feasibility of obtaining perioperative bedside BIA measurements in patients undergoing AHA surgery. BIA measurements correlated with fluid balance, weight changes, and postoperative clinical complications. BIA-assessed fluid status might add helpful information to guide fluid management in patients undergoing AHA surgery.

RESUMEN

Standardised peri-operative care pathways for patients undergoing emergency laparotomy or laparoscopy for non-traumatic pathologies have been shown to be inadequate and associated with high morbidity and mortality. Recent research has highlighted this problem and showed that simple pathways with 'rescue' interventions have been associated with reduced mortality when implemented successfully. These rescue pathways have focused on early diagnosis and surgery, specialist surgeon and anaesthetist involvement, goal-directed therapy and intensive or intermediary postoperative care for high-risk patients. In elective surgery, enhanced recovery has resulted in reduced length of stay and morbidity by the application of procedure-specific, evidence-based interventions inside rigorously implemented patient pathways based on multidisciplinary co-operation. The focus has been on attenuation of peri-operative stress and pain management to facilitate early recovery. Patients undergoing emergency laparotomy are a heterogeneous group consisting mostly of patients with intestinal perforations and/or obstruction with varying levels of comorbidity and frailty. However, present knowledge of the different pathophysiology and peri-operative trajectory of complications in these patient groups is limited. In order to move beyond rescue pathways and to establish enhanced recovery for emergency laparotomy, it is essential that research on both the peri-operative pathophysiology of the different main patient groups - intestinal obstruction and perforation - and the potentially differentiated impact of interventions is carried out. Procedure- and pathology-specific knowledge is lacking on key elements of peri-operative care, such as: multimodal analgesia; haemodynamic optimisation and fluid management; attenuation of surgical stress; nutritional optimisation; facilitation of mobilisation; and the optimal use and organisation of specialised wards and improved interdisciplinary collaboration. As such, the future challenges in improving peri-operative patient care in emergency laparotomy are moving from simple rescue pathways to establish research that can form a basis for morbidity- and procedure-specific enhanced recovery protocols as seen in elective surgery.

RESUMEN

Stable intraoperative haemodynamics are associated with improved outcome and even short periods of instability are associated with an increased risk of complications. During anaesthesia intermittent non-invasive blood pressure and heart rate remains the cornerstone of haemodynamic monitoring. Continuous monitoring of systemic blood pressure or even -flow requires invasive or advanced modalities creating a barrier for obtaining important real-time haemodynamic insight. The Peripheral Perfusion Index (PPI) is obtained continuously and non-invasively by standard photoplethysmography. We hypothesized that changes in indices of systemic blood flow during general anaesthesia would be reflected in the PPI. PPI, stroke volume (SV), cardiac output (CO) and mean arterial pressure (MAP) were evaluated in 20 patients. During general anaesthesia but before start of surgery relative changes of SV, CO and MAP were compared to the relative changes of PPI induced by head-up (HUT) and head-down tilt (HDT). Furthermore, the effect of phenylephrine (PE) during HUT on these parameters was investigated. ∆PPI correlated significantly (p < 0.001) with ∆SV (r = 0.9), ∆CO (r = 0.9), and ∆MAP (r = 0.9). HUT following induction of anaesthesia resulted in a decrease in PPI of 41% (25-52) [median (IQR)], SV 27% (23-31), CO 27% (25-35), and MAP 28% (22-35). HDT led to an increase in PPI of 203% (120-375), SV of 29% (21-41), CO 22% (16-34), and MAP 47% (42-60). After stabilizing a second HUT decreased PPI 59% (49-76), SV 33% (28-37), CO 31% (28-36), and MAP 34% (26-38). Restoration of preload with PE increased PPI by 607% (218-1078), SV by 96% (82-116), CO by 65% (56-99), and MAP by 114% (83-147). During general anaesthesia changes in PPI tracked changes in systemic haemodynamics.

RESUMEN

Postoperative delirium is common after hip fracture surgery, and may have a neuro-inflammatory cause. We conducted a single-centre, randomised, double-blind, placebo-controlled trial of 117 older hip fracture patients to see if a single, pre-operative intravenous dose of 125 mg methylprednisolone could reduce the severity and/or incidence of postoperative delirium, assessed using the Confusion Assessment Method delirium severity score. Modified intention-to-treat analysis found no significant difference in our primary outcome, median (IQR [range]) cumulative Confusion Assessment Method delirium severity score over the first three postoperative days between the methylprednisolone and placebo groups (1 (0-6 [0-39]) vs. 2 (0-10 [0-32]), p = 0.294). Both the prevalence of postoperative delirium (Confusion Assessment Method delirium severity score ≥ 5, 10/59 vs. 19/58, p = 0.048) and the median (IQR [range]) cumulated postoperative (by day 3) fatigue scores (5 (2-6 [0-11]) vs. 6 (4-8 [0-16]), p = 0.008) were significantly lower in the methylprednisolone compared with the placebo group. There were no significant between-group differences in the rate of completing physiotherapy, postoperative pain, the administration of antipsychotic drugs, infection, length of inpatient stay or 30- and 90-day mortality. No major adverse reactions related to methylprednisolone were recorded. We conclude that a single, pre-operative dose of 125 mg methylprednisolone does not reduce the severity of postoperative delirium, but may reduce both the prevalence of delirium and the severity of fatigue after hip fracture surgery in older patients, enabling remobilisation and recovery.

RESUMEN

As longevity increases globally, the number of older, frailer, comorbid patients requiring fragility fracture surgery will increase. Fundamentally, anaesthesia should aim to maintain these patients' pre-fracture cognitive and physiological trajectories and facilitate early (ie day 1) postoperative recovery. This review describes the 10 general principles of anaesthesia for fragility fracture surgery that best achieve these aims: multidisciplinary care, 'getting it right first time', timely surgery, standardisation, sympathetic anaesthesia, avoiding ischaemia, sympathetic analgesia, re-enablement, data collection and training.

RESUMEN

BACKGROUND: In a frail patient group often suffering from dehydration, hip fracture is potentially fatal partly because of the blood loss and thus deteriorated circulation. An important goal for haemodynamic monitoring and resuscitation is early detection of insufficient tissue perfusion. "The peripheral perfusion index" reflects changes in peripheral perfusion and blood volume. We hypothesize that hip fracture patients are hypovolaemic with poor peripheral perfusion and accordingly respond to controlled fluid resuscitation. The peripheral perfusion index might reflect restricted tissue perfusion in spite of stable central haemodynamic variables. METHODS: This prospective observational study assess to what extend hip fracture patients suffer from hypovolaemia and respond to a stroke volume-guided fluid challenge. The secondary objectives are to evaluate correlation between the non-invasive peripheral perfusion index and minimally invasive measures of stroke volume, changes in blood volume and near-infrared spectroscopy determined tissue- and cerebral oxygenation and to compare results to prevalence of post-operative complications including mortality. We will include 50 patients (>65 years) presenting a hip fracture and treated in a multimodal fast-track regimen when written informed consent is available. DISCUSSION: This is likely the first study to address pre-operative haemodynamic monitoring and resuscitation in hip fracture patients where adequate resuscitation is easily missed. We aim to evaluate feasibility of pre-operative stroke volume-guided haemodynamic optimization in the context of minimally- and non-invasive monitoring of peripheral perfusion and measure of blood volume.

RESUMEN

This study explores the association between postadmission and intraoperative cerebral oxygenation (ScO2), reflecting systemic perfusion, and postoperative mortality and delirium. Forty elderly (age > 65 years) patients with hip fractures were included in this prospective observational study. The ScO2 was determined using near-infrared spectroscopy at initial resuscitation after patients were admitted to the hospital and during surgery. Postoperative delirium was assessed up to seven days after surgery using the memorial delirium assessment scale and the confusion assessment method. Ten patients (25%) developed postoperative delirium within the first seven postoperative days. At initial resuscitation ScO2 was lower in patients that later developed delirium, but the difference was not significant (p = 0.331). Intraoperative ScO2 values remained similar in the two groups. Mortality regardless of cause was 10% (4 out of 40 patients) after 30 days. At initial resuscitation ScO2 was significant lower in the mortality group than in the surviving group (p = 0.042), and the ScO2 nadir values were also significant lower (p = 0.047). Low ScO2 during initial resuscitation (defined as ScO2 < 55 for a minimum of two consecutive minutes) was also significantly associated with 30-day mortality (p = 0.015). There were no associations between low blood pressure and postoperative delirium or 30-day mortality. We found that low preoperative ScO2 was better associated with 30-day all-cause mortality in elderly patients undergoing surgery for hip fracture than blood pressure measurements. Future studies in preoperative resuscitation of hip fracture patients should focus on perfusion measures as opposed to conventional haemodynamic.

RESUMEN

BACKGROUND: Acute high-risk abdominal (AHA) surgery carries a very high risk of morbidity and mortality and represents a massive healthcare burden. The aim of the present study was to evaluate the effect of a standardized multidisciplinary perioperative protocol in patients undergoing AHA surgery. METHODS: The AHA study was a prospective single-centre controlled study in consecutive patients undergoing AHA surgery, defined as major abdominal pathology requiring emergency laparotomy or laparoscopy including reoperations after elective gastrointestinal surgery. Consecutive patients were included after initiation of the AHA protocol as standard care. The intervention cohort was compared with a predefined, consecutive historical cohort of patients from the same department. The protocol involved continuous staff education, consultant-led attention and care, early resuscitation and high-dose antibiotics, surgery within 6 h, perioperative stroke volume-guided haemodynamic optimization, intermediate level of care for the first 24 h after surgery, standardized analgesic treatment, early postoperative ambulation and early enteral nutrition. The primary outcome was 30-day mortality. RESULTS: Six hundred patients were included in the study and compared with 600 historical controls. The unadjusted 30-day mortality rate was 21·8 per cent in the control cohort compared with 15·5 per cent in the intervention cohort (P = 0·005). The 180-day mortality rates were 29·5 and 22·2 per cent respectively (P = 0·004). CONCLUSION: The introduction of a multidisciplinary perioperative protocol was associated with a significant reduction in postoperative mortality in patients undergoing AHA surgery.

RESUMEN

Mortality and morbidity occur commonly following emergency laparotomy, and incur a considerable clinical and financial healthcare burden. Limited data have been published describing the postoperative course and temporal pattern of complications after emergency laparotomy. We undertook a retrospective, observational, multicentre study of complications in 1139 patients after emergency laparotomy. A major complication occurred in 537/1139 (47%) of all patients within 30 days of surgery. Unadjusted 30-day mortality was 20.2% and 1-year mortality was 34%. One hundred and thirty-seven of 230 (60%) deaths occurred between 72 h and 30 days after surgery; all of these patients had complications, indicating that there is a prolonged period with a high frequency of complications and mortality after emergency laparotomy. We conclude that peri-operative, enhanced recovery care bundles for preventing complications should extend their focus on continuous complication detection and rescue beyond the first few postoperative days.

RESUMEN

AIMS: We chose unstable extra-capsular hip fractures as our study group because these types of fractures suffer the largest blood loss. We hypothesised that tranexamic acid (TXA) would reduce total blood loss (TBL) in extra-capsular fractures of the hip. PATIENTS AND METHODS: A single-centre placebo-controlled double-blinded randomised clinical trial was performed to test the hypothesis on patients undergoing surgery for extra-capsular hip fractures. For reasons outside the control of the investigators, the trial was stopped before reaching the 120 included patients as planned in the protocol. RESULTS: In all 72 patients (51 women, 21 men; 33 patients in the TXA group, 39 in the placebo group) were included in the final analysis, with a significant mean reduction of 570.8 ml (p = 0.029) in TBL from 2100.4 ml (standard deviation (sd) = 1152.6) in the placebo group to 1529.6 ml (sd = 1012.7) in the TXA group. The 90-day mortality was 27.2% (n = 9) in the TXA group and 10.2% (n = 4) in the placebo group (p = 0.07). We were not able to ascertain a reliable cause of death in these patients. DISCUSSION: TXA significantly reduced TBL in extra-capsular hip fractures, but concerns regarding its safety in this patient group must be investigated further before the use of TXA can be recommended. TAKE HOME MESSAGE: We present a randomised clinical trial that is unique in the literature. We evaluate the effect of TXA in very homogenous population - extra-capsular fractures operated with short intramedullary nails. Cite this article: Bone Joint J 2016;98-B:747-53.

RESUMEN

BACKGROUND: Emergency upper gastrointestinal bleeding is a common condition with high mortality. Most patients undergo oesophagogastroduodenoscopy (OGD), but no universally agreed approach exists to the type of airway management required during the procedure. We aimed to compare anaesthesia care with tracheal intubation (TI group) and without airway instrumentation (monitored anaesthesia care, MAC group) during emergency OGD. METHODS: This was a prospective, nationwide, population-based cohort study during 2006-13. Emergency OGDs performed under anaesthesia care were included. End points were 90 day mortality (primary) and length of stay in hospital (secondary). Associations between exposure and outcomes were assessed in logistic and linear regression models, adjusted for the following potential confounders: shock at admission, level of anaesthetic expertise present, ASA score, Charlson comorbidity index score, BMI, age, sex, alcohol use, referral origin (home or in-hospital), Forrest classification, ulcer localization, and postoperative care. RESULTS: The study group comprised 3580 patients under anaesthesia care: 2101 (59%) for the TI group and 1479 (41%) for the MAC group. During the first 90 days after OGD, 18.9% in the TI group and 18.4% in the MAC group died, crude odds ratio=1.03 [95% confidence interval (CI)=0.87-1.23, P=0.701], adjusted odds ratio=0.95 (95% CI=0.79-1.15, P=0.590). Patients in the TI group stayed slightly longer in hospital [mean 8.16 (95% CI=7.63-8.60) vs 7.63 days (95%=CI 6.92-8.33), P=0.108 in adjusted analysis]. CONCLUSIONS: In this large population-based cohort study, anaesthesia care with TI was not different from anaesthesia care without airway instrumentation in patients undergoing emergency OGD in terms of 90 day mortality and length of hospital stay.

RESUMEN

BACKGROUND: Hip fracture patients experience high pain levels during postoperative rehabilitation. The role of surgical technique on postoperative pain has not been evaluated previously. METHODS: One hundred and seventeen hip fracture patients were included in a descriptive prospective study. All patients received continuous epidural analgesia and were treated according to a standardized perioperative rehabilitation programme. Resting pain, pain on hip flexion, and walking were measured during daily physiotherapy sessions on a verbal five-point rating scale during the first four postoperative days. Patients were stratified into four groups according to surgical procedure: screws or pins, arthroplasty, dynamic hip screw (DHS), and intra-medullary hip screw (IMHS). RESULTS: Cumulated pain levels were significantly different between surgical procedures both for hip flexion (P=0.002) and for walking (P=0.02) with highest dynamic pain levels for patients who had either DHSs or IMHSs compared with arthroplasty or parallel implants. There were significant negative correlations between ambulatory capacity assessed by the cumulated ambulation score and both the dynamic cumulated pain scores on hip flexion (r=-0.43, P<0.001) and walking (r=-0.36, P=0.004). CONCLUSIONS: Postoperative pain levels after surgery for hip fracture are dependent on the surgical procedure, which should be taken into account in future studies of analgesia and rehabilitation.
