Transfusión en anestesia obstétrica
Blood transfusion practices in obstetric anaesthesia.

Abstract
Blood transfusion is an essential component of emergency obstetric care and appropriate blood transfusion significantly reduces maternal mortality. Obstetric haemorrhage, especially postpartum haemorrhage, remains one of the major causes of massive haemorrhage and a prime cause of maternal mortality. Blood loss and assessment of its correct requirement are difficult in pregnancy due to physiological changes and comorbid conditions. Many guidelines have been used to assess the requirement and transfusion of blood and its components. Infrastructural, economic, social and religious constraints in blood banking and donation are key issues to formulate practice guidelines. Available current guidelines for transfusion are mostly from the developed world; however, they can be used by developing countries keeping available resources in perspective. KEYWORDS:

Encuesta nacional de control del dolor después de cesárea
National survey of postoperative pain control after cesarean delivery.
Isr Med Assoc J. 2014 Mar;16(3):153-6.
Abstract
BACKGROUND: Postoperative pain is a common problem after cesarean deliveries. OBJECTIVES: To characterize common obstetric anesthesia practices after cesarean deliveries in Israel in order to standardize postoperative pain relief protocols. METHODS: A questionnaire was completed during an interview with every obstetric anesthesia unit in all 25 delivery wards in Israel. Data were gathered on intraoperative anesthesia and analgesia protocols as well as postoperative pain relief protocols. A sub-analysis compared units whose director completed a formal obstetric anesthesia training program with those whose directors did not. RESULTS: Neuraxial morphine was used routinely in 12% of hospitals. No unit providing intrathecal morphine complied with American Society of Anesthesiologists guidelines for respiratory monitoring after use of neuraxial opioids. Additionally, non-steroidal anti-inflammatory drugs (NSAIDs) .were used routinely in only half the wards, while patient-controlled analgesia was used infrequently. Postoperative verbal analog scores were not recorded routinely in 71% of units on postoperative day 1. The unit director's training significantly influenced the unit protocols. CONCLUSIONS: Intrathecal morphine, the gold standard of care in cesarean deliveries, is rarely used, mainly due to shortage of staff and lack of formal obstetric anesthesia training. In addition, NSAIDs are also underused. There is a need for more formal training for obstetric anesthesiologists in Israel.
Evaluación de técnicas antihipotensoras en cesárea con anestesia raquídea. Cristaloides rápidos vs efedrina intravenosa
Evaluation of antihypotensive techniques for cesarean section under spinal anesthesia: Rapid crystalloid hydration versus intravenous ephedrine.
Anesth Essays Res. 2016 Sep-Dec;10(3):637-642.
Abstract
BACKGROUND: Spinal anesthesia is a preferred technique over general anesthesia for cesarean delivery. It avoids maternal airway related complications, aspiration and neonatal depression. However hypotension following spinal anesthesia can lead to decrease in uterine blood flow and neonatal hypoxia. AIMS: We aimed to evaluate the efficacy of 15 mL.kg- 1of crystalloid preloading versus prophylactic intravenous bolus of 10 mg ephedrine as an antihypotensive measure for cesarean section. METHODS: A prospective randomized double blind study was conducted in hundred ASA grade I/II parturient undergoing cesarean section, allocated to group P (n=50) who received preloading with ringer lactate 15 mL.kg- 1 over 20 minutes before spinal anesthesiaand group E (n=50) received intravenous bolus of 10mg ephedrine within one minute of spinal anesthesia with 10mg of hyperbaric bupivacaine 0.5% at L2-3/L3-4 level. They were monitored for incidences of hypotension, need of rescue doses of ephedrine, Apgar score and adverse events. Appropriate statistical tests were applied and P < 0.05 was considered as significant. RESULTS: Incidence of hypotension within 20 minutes of spinal anesthesia was significantly less in group E (28%) as compared to group P (58%) and need of rescue doses were more in group P. Adverse events like nausea vomiting and shivering were less in group E. Apgar score were better in group E than in group P delivered babies. CONCLUSION: Prophylactic intravenous bolus of 10mg ephedrine with spinal injection is more effective in maintaining maternal hemodynamic stability and better neonatal outcome as compared to crystalloid preloading during cesarean delivery.
