ReviewThe use of processed electroencephalography (pEEG) in obstetric anaesthesia: a narrative review.
Accidental awareness under general anaesthesia (AAGA) remains a major complication of anaesthesia. The incidence of AAGA during obstetric anaesthesia is high relative to other specialities. The use of processed electroencephalography (pEEG) in the form of "depth of anaesthesia" monitoring has been shown to reduce the incidence of AAGA in the non-obstetric population. ⋯ In addition, pEEG acts as a surrogate marker of cerebral perfusion, and thus as an additional monitor for impending cardiovascular collapse, as seen in amniotic fluid embolism. The subtle physiological and pathological changes in EEG activity that may occur during pregnancy are an unexplored research area in the context of anaesthetic pEEG monitors. We believe that the direction of clinical practice is moving towards greater use of pEEG monitoring and individualisation of anaesthesia.

Balanced Nonopioid General Anesthesia With Lidocaine Is Associated With Lower Postoperative Complications Compared With Balanced Opioid General Anesthesia With Sufentanil for Cardiac Surgery With Cardiopulmonary Bypass: A Propensity Matched Cohort Study.
There are no data on the effect of balanced nonopioid general anesthesia with lidocaine in cardiac surgery with cardiopulmonary bypass. The main study objective was to evaluate the association between nonopioid general balanced anesthesia and the postoperative complications in relation to opioid side effects. ⋯ A balanced nonopioid general anesthesia protocol with lidocaine was associated with lower odds of postoperative complication composite outcome based on respiratory failure and confusion.

Randomized Controlled Trial Multicenter Study
Effective dose of ephedrine for treatment of hypotension after induction of general anaesthesia in neonates and infants less than 6 months of age: a multicentre randomised, controlled, open label, dose escalation trial.
The recommended dose of ephedrine in adults (0.1 mg kg-1) frequently fails to treat hypotension after induction of general anaesthesia in neonates and infants less than 6 months of age. The aim of this study was to determine the optimal dose of ephedrine in this population for the treatment of hypotension after induction of general anaesthesia with sevoflurane. ⋯ NCT02384876.

Randomized Controlled TrialEfficacy of femoral periarterial block in preventing thigh tourniquet pain: a randomized controlled trial.
Tourniquet pain, described as a dull, tight, poorly localized aching sensation, is common in conscious patients. Although various pain-reduction methods have been implemented, none are completely effective. Femoral periarterial block (FAB) has been shown to attenuate tourniquet-induced hypertension in patients undergoing general anesthesia. We aimed to test the feasibility of FAB in inhibiting thigh tourniquet pain in orthopedic patients under conscious sedation. ⋯ FAB, applied with regional anesthesia in patients undergoing below-knee orthopedic surgeries, could reduce thigh tourniquet pain, stabilize blood pressure and heart rate, and prolong tourniquet duration.
