Randomized Controlled TrialUltrasound to identify the lumbar space in women with impalpable bony landmarks presenting for elective caesarean delivery under spinal anaesthesia: a randomised trial.
Ultrasound can facilitate neuraxial blockade in patients with poorly defined anatomical surface landmarks, but there are no studies comparing an ultrasound-guided technique with landmark palpation for spinal anaesthesia. The objective of this study was to compare pre-procedural lumbar ultrasonography with landmark palpation to locate the needle insertion point in women with impalpable lumbar spinous processes presenting for caesarean delivery. ⋯ The use of ultrasonography to locate the needle insertion point reduced the number of needle passes in women with impalpable lumbar spinous processes undergoing elective caesarean delivery under spinal anaesthesia. Its use did not prolong overall procedural time.

Observational StudySevere maternal morbidity in a general intensive care unit in Nigeria: clinical profiles and outcomes.
Data on outcomes of obstetric admissions to intensive care units can serve as useful markers for assessing the quality of maternal care. We evaluated the intensive care unit utilization rate, diagnoses, case-fatality rate, mortality rate and associated factors among obstetric patients. ⋯ Direct obstetric morbidities constituted the leading reasons for obstetric admissions to the intensive care unit, with sepsis accounting for the highest case-fatality rate. Abdominal delivery and/or peripartum hysterectomy increased risk of death among obstetric admissions.

Determination of ED50 of hydromorphone for postoperative analgesia following cesarean delivery.
Morphine is the most common opioid injected into the intrathecal space for postoperative analgesia following cesarean delivery, but ongoing medication shortages have resulted in limited availability. One proposed morphine alternative is hydromorphone. Studies investigating its use in post-cesarean analgesia are limited. This study was conducted to determine the median effective dose of intrathecal hydromorphone 12h postpartum. ⋯ Intrathecal hydromorphone may be an effective alternative to morphine for post-cesarean pain management. The amount of intrathecal hydromorphone necessary to provide analgesia at 12h postoperatively may be significantly lower than doses currently in use. Further research should be performed to identify the optimal dose of intrathecal hydromorphone for post-surgical pain relief.

Case ReportsAnesthetic management of a parturient with varicella presenting for cesarean delivery.
Varicella (chicken pox) infection is associated with a significant risk of maternal and fetal morbidity and mortality. The choice of anesthetic technique, either neuraxial or general anesthesia, in such patients remains controversial. ⋯ We present the anesthetic management of a 25-year-old parturient with acute varicella infection who underwent emergency cesarean delivery under spinal anesthesia. The risks and benefits of neuraxial anesthesia in the setting of varicella are discussed.
