RESUMEN

INTRODUCTION: Hip fractures are often encountered in the elderly and present special problems to the anaesthesiologist. Fascia iliaca compartment block is another technique with the intent to block all the three nerves like 3-in-1 nerve block. AIM: To evaluate the analgesic efficacy of ultrasound guided fascia iliaca compartment block to facilitate positioning of patients with hip fracture for spinal anaesthesia. MATERIALS AND METHODS: This prospective study was conducted in 50 patients aged between 40-80 years, belonging to American Society of Anesthesiologists (ASA) physical status I-III undergoing surgery for hip fracture. All 50 patients received an ultrasound guided Fascia Iliaca Compartment Block (FICB) in the premedication room with 30 mL of 0.5% ropivacaine by 23G spinal needle. Sensory blockade was evaluated 5, 10 and 20 minutes after ropivacaine administration using loss of perception to cold in the lateral, anterior and medial part of the thigh. Visual analogue scale scores were noted before the block, 20 minutes after block and during positioning for spinal anaesthesia. Patient's acceptance for FICB was evaluated 24 hour after arriving back to the orthopaedics ward using a two-point score. Any episode of hypotension or bradycardia was noted and managed accordingly. RESULTS: In lateral part of thigh, at 5 minutes sensory blockade was present in 33 patients (66%) and at 10 minutes sensory blockade was present in 45 cases (90%). In anterior part of thigh, sensory blockade was present in 34 cases (68%) at 5 minutes time interval and at 10 minutes sensory blockade was present in 48 cases (96%). In medial part of thigh, 28 cases (56%) had sensory blockade at 5 minutes and at 10 minutes in 43 cases (86%). Sensory blockage was same at 20 minutes as on 10 minutes interval in all thigh parts. Before FIC block average VAS was 7.5 which was decreased to average of 2.94 at 20 minutes after block which was statistically significant (p<0.01). During positioning for spinal anaesthesia, 46 patients had VAS less than 4. Positioning during spinal anaesthesia was assessed unsatisfactory (0) in 2 cases (4%), satisfactory (1) in 5 cases (10%), good (2) in 25 cases (50%) and excellent (3) in 18 cases (36%). CONCLUSION: Ultrasound guided FICB can be performed safely without complications in controlling pain for patients with hip fracture. Performing an FICB before positioning for spinal anaesthesia provides good pain management and facilitates spinal performance with wide patient acceptance, hence improving overall quality and efficiency of care.

RESUMEN

Amniotic fluid embolism (AFE) is one of the catastrophic complications of pregnancy in which amniotic fluid, fetal cells, hair, or other debris enters into the maternal pulmonary circulation, causing cardiovascular collapse. Etiology largely remains unknown, but may occur in healthy women during labour, during cesarean section, after abnormal vaginal delivery, or during the second trimester of pregnancy. It may also occur up to 48 hours post-delivery. It can also occur during abortion, after abdominal trauma, and during amnio-infusion. The pathophysiology of AFE is not completely understood. Possible historical cause is that any breach of the barrier between maternal blood and amniotic fluid forces the entry of amniotic fluid into the systemic circulation and results in a physical obstruction of the pulmonary circulation. The presenting signs and symptoms of AFE involve many organ systems. Clinical signs and symptoms are acute dyspnea, cough, hypotension, cyanosis, fetal bradycardia, encephalopathy, acute pulmonary hypertension, coagulopathy etc. Besides basic investigations lung scan, serum tryptase levels, serum levels of C3 and C4 complements, zinc coproporphyrin, serum sialyl Tn etc are helpful in establishing the diagnosis. Treatment is mainly supportive, but exchange transfusion, extracorporeal membrane oxygenation, and uterine artery embolization have been tried from time to time. The maternal prognosis after amniotic fluid embolism is very poor though infant survival rate is around 70%.

RESUMEN

Anesthesia for magnetic resonance imaging (MRI) requires special equipment that can be used in the presence of a magnetic field. Endotracheal tube and various laryngeal mask airway devices have a variable quantity of ferromagnetic material in the pilot balloon that could reduce image quality and result in artifacts. The i-gel is a reliable, easily inserted airway device, and causes minimal interference in image quality. We used i-gel in 10 anaesthetized adult patients undergoing MRI. The quality of image, evidence of airway, tongue, and dental trauma were assessed throughout the procedure. All scans were diagnostically adequate. Therefore, we concluded that i-gel causes the least ferromagnetic interference compared with other devices and improves the quality of imaging and produces minimal artifact while scanning.

RESUMEN

BACKGROUND: Spasticity is a syndrome associated with a persistent increase in involuntary reflex activity of a muscle in response to stretch. Adductor muscle spasticity is a common complication of spinal cord and brain injury. It needs to be treated if it interferes with activities of daily living and self-care. Obturator neurolytic blockade is one of the cost-effective therapeutic possibilities to treat spasticity of adductor group of muscles. In this study, we assessed the efficacy of interadductor approach in alleviating the spasticity. METHODS: Obturator neurolysis using 8-10 ml 6% phenol was given with the guidance of a peripheral nerve stimulator in 20 spastic patients. Technical evaluation included number of attempted needle insertions, time to accurate location of the nerve, depth of needle insertion, and success rate. Pain, spasticity, hip abduction range of motion (ROM), number of spasms, gait, and hygiene were evaluated at 1(st) hour, 24(th) hour, end of the 1(st) week, and in the 1(st), 2(nd), and 3(rd) months following the intervention. RESULTS: The success rate was 100% with mean time to accurate nerve location 4.9±2.06 min. Average depth of needle insertion was 2.91±0.32 cm. Compared with the scores measured immediately before the block, all studied parameters improved significantly. An increase in the Modified Ashworth Scale values was observed in the 2(nd) and 3(rd) months, but they did not reach their initial values. CONCLUSION: The interadductor approach proved to be accurate and fast, with a high success rate. Phenol blockade is an efficient and cost-effective technique in patients with adductor spasticity. It led to a decrease in spasticity and pain with an increase in the ROM of the hip and better hygiene, with an efficacy lasting for about 3 months.

RESUMEN

This review of the long-term management of spasticity addresses some of the clinical dilemmas in the management of patients with chronic disability. It is important for clinicians to have clear objectives in patient treatment and the available treatment strategies. The review reiterates the role of physical treatment in the management, and thereafter the maintenance of patients with spasticity. Spasticity is a physiological consequence of an injury to the nervous system. It is a complex problem which can cause profound disability, alone or in combination with the other features of an upper motor neuron syndrome, and can give rise to significant difficulties in the process of rehabilitation. This can be associated with profound restriction to activity and participation due to pain, weakness, and contractures. Optimum management is dependent on an understanding of its underlying physiology, an awareness of its natural history, an appreciation of the impact on the patient, and a comprehensive approach to minimizing that impact. The aim of this article is to highlight the importance, basic approach, and management options available to the general practitioner in such a complex condition.

RESUMEN

La obesidad se ha identificado como un factor importante de riesgo de morbimortalidad relacionada con anestesia en obstetricia. La obesidad acentúa la mayoría de los cambios fisiológicos del embarazo. Las parturientas obesas tienen un mayor riesgo de presentar problemas médicos concomitantes o enfermedades prenatales, entre ellas la preeclampsia y la diabetes gestacional. Estas pacientes requieren valoración preoperatoria minuciosa, una preparación meticulosa y alistamiento para una vía aérea difícil, puesto que la incidencia de intubación fallida es mucho más alta en ellas. Siempre que sea posible, la anestesia regional es la mejor alternativa en este grupo de pacientes.


Obesity has been identified as a significant risk factor for anaesthesia related morbi-dity/mortality in obstetrics. Obesity compounds most of the physiological changes in pregnancy. The obese parturients are at increased risk of having either concurrent medical problems or superimposed antenatal diseases including preeclampsia and gestational diabetes. These patients need thorough preoperative assessment, meticulous preparation and preparation for difficult airway as incidence of failed intubation is many times higher in these patients. Regional anaesthesia whenever possible is the best choice in this group of patients.

RESUMEN

BACKGROUND: Clonidine is added to intrathecal local anesthetics to improve intraoperative analgesia and to increase the duration of sensory and motor block. Aim of this study was to evaluate and compare the effects of addition of two different doses of clonidine (15 and 30 mcg) to 11 mg hyperbaric bupivacaine in patients undergoing inguinal herniorrhaphy surgery under spinal anesthesia. MATERIALS AND METHODS: Seventy-five patients enrolled in the study were randomly divided into three groups of 25 each. Group I patients received 11 mg hyperbaric bupivacaine, whereas groups II and III received 15 mcg and 30 mcg clonidine, respectively, as an adjuvant to 11 mg hyperbaric bupivacaine. The volume of solution was kept constant to 2.4 ml by adding saline wherever needed. RESULTS: Highest level of sensory block, time to achieve this level, and highest Bromage scale recorded were comparable among the groups. The mean time to two-segment regression, regression of sensory block to L3 dermatome, and mean duration of motor block were the greatest in group III followed by group II and group I. There was significant fall in mean arterial pressure (MAP) in groups II and III as compared to group I (P = 0.04). Episodes of hypotension were more in group III than in group II. CONCLUSION: 30 mcg clonidine was associated with more incidence and duration of hypotension than 15 µg of clonidine. 15 mcg clonidine added to 11 mg hyperbaric bupivacaine provides better sensory and motor blockade for inguinal herniorrhaphy.

RESUMEN

Spasticity is motor alteration characterized by muscle hypertonia and hyperreflexia. It is an important complication of spinal cord injury, traumatic brain injury, cerebral palsy, and multiple sclerosis. If uncorrected, fibrosis and eventually bony deformity lock the joint into a fixed contracture. Chemical neurolysis using various agents is one of the therapeutic possibilities to alleviate spasticity. We are, hereby, reporting 3 patients in whom 65% alcohol was used as neurolytic agent for the treatment of hip adductor spasticity, and the effect lasted for a variable period.

RESUMEN

BACKGROUND: Clinical tests, such as loss of verbal contact, eyelash reflex, corneal reflex, and jaw relaxation, are used to assess the depth of anesthesia. "Trapezius squeeze test" (TST) is one such clinical test. It is a simple test to perform in which 1-2 inches of trapezius muscle is held and squeezed in full thickness and response is evaluated in the form of toe/body movement. MATERIALS AND METHODS: One hundred pediatric patients between 3 and 5 years of age, scheduled to undergo elective surgery, were included in this study. We evaluated negative TST as an indicator for optimal anesthesia depth for laryngeal mask airway (LMA) insertion in anesthetized spontaneously breathing children. Anesthesia was induced using 4% sevoflurane in oxygen. As the child lost the verbal contact or loss of body movement, TST was performed. Test was repeated every 15 s till it became negative. When the TST became negative, a well lubricated, appropriate-size LMA was inserted. RESULTS: Mean time for TST to become negative in our study was 271.80 ± 55.8 s and ease of insertion was excellent in 91 patients and acceptable in 9 patients. LMA was successfully inserted in first attempt in 96% patients. CONCLUSIONS: Negative TST is a reliable indicator for placement of LMA in spontaneously breathing children. Excellent conditions for LMA placement are present in majority of the patients without any untoward effects at this point of time.

RESUMEN

BACKGROUND: Pregabalin is a potent ligand for alpha-2-delta subunit of voltage-gated calcium channels in the central nervous system, which exhibits potent anticonvulsant, analgesic and anxiolytic activity. The pharmacological activity of pregabalin is similar to that of gabapentin and shows possible advantages. Although it shows analgesic efficacy against neuropathic pain, very limited evidence supports its postoperative analgesic efficacy. We investigated its analgesic efficacy in patients experiencing acute pain after abdominal hysterectomy and compared it with gabapentin and placebo. METHODS: A randomized, double-blind, placebo-controlled study was conducted in 90 women undergoing abdominal hysterectomy who were anaesthetized in a standardized fashion. Patients received 300 mg pregabalin, 900 mg gabapentin or placebo, 1-2 hours prior to surgery. Postoperative analgesia was administered at visual analogue scale (VAS) ≥3. The primary outcome was analgesic consumption over 24 hours and patients were followed for pain scores, time to rescue analgesia and side effects as secondary outcomes. RESULTS: The diclofenac consumption was statistically significant between pregabalin and control groups, and gabapentin and control groups; however, pregabalin and gabapentin groups were comparable. Moreover, the consumption of tramadol was statistically significant among all the groups. Patients in pregabalin and gabapentin groups had lower pain scores in the initial hour of recovery. However, pain scores were subsequently similar in all the groups. Time to first request for analgesia was longer in pregabalin group followed by gabapentin and control groups. CONCLUSION: A single dose of 300 mg pregabalin given 1-2 hours prior to surgery is superior to 900 mg gabapentin and placebo after abdominal hysterectomy. Both the drugs are better than placebo.

RESUMEN

The overall goal of the global oximetry (GO) project was to increase patient safety during anaesthesia and surgery in low and middle income countries by decreasing oximetry costs and increasing oximetry utilisation. Results from the overall project have been previously published. This paper reports specifically on pilot work undertaken in four hospitals in one Indian State. The aim of this work was to assess the impact of increasing oximetry provision in terms of benefits to anaesthetists and in the identification of patient problems during anaesthesia, to identify training needs and to explore perceptions regarding barriers to more comprehensive oximetry coverage. Data collection was by interview with hospital staff, use of a log-book to capture data on desaturation episodes and a follow-up questionnaire at 10 months after the introduction of additional oximeters. Increasing oximetry utilisation in the four hospitals was viewed positively by the anaesthetic staff and enabled improvement in monitoring patients. Of the 939 monitored patients studied, 214 patients (23%) experienced a total of 397 desaturation episodes. For nearly half of the patients undergoing caesarean section under regional anaesthesia following a desaturation event supplementary oxygen was required. In 53 of the 379 female sterilisations (14%) desaturation episodes occurred and in eight patients, there were 17 episodes of desaturation due to obstruction. In the recovery room, 91 of the 939 patients were monitored using the oximeters with 12 patients (13%) requiring oxygen. This study has highlighted that pulse oximetry must be used even in patients having surgical procedures or caesarean section under regional or local anaesthesia as these procedures are associated with hypoxic episodes. Anaesthetists must ensure they are complying with the Indian Society of Anaesthesiologists monitoring standards for anaesthesia and ensure patients are monitored by pulse oximetry.
