RESUMEN
BACKGROUND: The way that pain is assessed in the PACU could impact on postoperative pain and analgesic consumption. However, there is currently no evidence to support this speculation. The authors hypothesised that using a comfort scale reduces postoperative opioid consumption when compared with a standard numerical rating scale (NRS) to evaluate pain in the PACU. METHODS: In this cluster-randomised trial, patients were assessed using either a comfort scale (comfort group) or a pain NRS (NRS group). The primary outcome was the opioid consumption in the PACU. The main secondary outcomes were postoperative pain, nausea and vomiting, length of stay in the PACU, and satisfaction. RESULTS: Of 885 randomised patients, 860 were included in the analysis. Opioid consumption in the PACU was comparable in the comfort and NRS groups (median [interquartile range [IQR] 0 (0-5) vs 0 (0-6); P=0.2436), irrespective of the type of surgical procedure. The majority of patients did not need any postoperative opioid (59% in the comfort group and 56% in the NRS group, P=0.2260). There was no difference in postoperative pain, nausea and vomiting, time to reach an Aldrete score ≥9 after extubation, and global satisfaction. CONCLUSIONS: Using a comfort scale to assess pain in the PACU did not spare any opioid compared with use of a standard NRS. Further studies focusing on patients at risk of increased postoperative opioid consumption are necessary. CLINICAL TRIAL REGISTRATION: NCT05234216.
RESUMEN
PURPOSE: Postpartum hemorrhage affects 5% of parturients. Its prevention relies mainly on the administration of oxytocin derivatives. Carbetocin is a newly available analogue of oxytocin but has a considerable incidence of side effects. CLINICAL FEATURES: We report the case of a woman with no cardiovascular risk factors experiencing an acute coronary syndrome with significant electrocardiogram changes perioperatively after a single injection of carbetocin during an emergency Cesarean delivery. Postoperative cardiac enzyme levels and transthoracic echocardiogram results were normal. CONCLUSION: A 2012 retrospective analysis of the use of carbetocin in our institution revealed an incidence rate for coronary events of 1/245 (0.34%), a rate similar to the ones reported in previous studies. We discuss the management of patients with angina during a Cesarean delivery as well as the plans to care for these patients in the future.

BACKGROUND: High-volume haemofiltration (HVHF) has been suggested as an adjuvant treatment of septic shock due to its capacities to remove from blood both pro- and anti-inflammatory mediators involved in the sepsis syndrome. Adsorption properties of some haemofiltration membranes are also interesting with this indication because inflammatory mediators are caught in the membrane itself. The aim of this study was to determine the haemodynamic and immunological effects of a new haemofiltration membrane, which has enhanced adsorption properties due to a special surface treatment, allowing the adsorption of endotoxins. METHODS: We compared this membrane to a standard haemofiltration membrane both in vitro and in 20 sepsis-induced pigs, randomized in two groups. One group was haemofiltered with the treated membrane and the other with the standard haemofiltration membrane during 6-h HVHF sessions. RESULTS: At the end of the experiment, mean +/- SD crystalloids requirements (5937 +/- 1588 versus 7587 +/- 1456 ml, P = 0.026), colloids requirements (1437 +/- 320 versus 1912 +/- 538 ml, P = 0.027), lactic acidosis (pH = 7.20 +/- 0.11 versus 7.10 +/- 0.07, P = 0.026) and pulmonary arterial hypertension (MPAP = 24 +/- 7 versus 34 +/- 8 mmHg, P = 0.008) were less pronounced when HVHF was performed with the treated membrane. In addition, mean +/- SD endotoxins levels were lower in the treated membrane group after 1 hour of HVHF (1.91 +/- 1.19 versus 11.07 +/- 10.64 EU/ml, P = 0.035). Cytokines levels were not different between groups except for IL-1beta, which was slightly lower in the treated membrane group. CONCLUSIONS: The use of a membrane with enhanced adsorption properties during a 6-h HVHF session in septic pigs improves haemodynamics compared to a standard haemofiltration membrane. These results are probably due to an efficient endotoxins and cytokines adsorption. A human study using this membrane is now necessary to confirm these results.
