Anaesthesia
-
Wound infiltration with local anaesthetics is a simple, effective and inexpensive means of providing good analgesia for a variety of surgical procedures without any major side-effects. In particular, local anaesthetic toxicity, wound infection and healing do not appear to be major considerations. The purpose of this review is to outline the existing literature on a procedure-specific basis and to encourage a more widespread acceptance of the technique, ensuring that all layers are infiltrated in a controlled and meticulous manner.

Randomized Controlled Trial
Modification of Tp-e and QTc intervals during caesarean section under spinal anaesthesia.
There are no guidelines for the anaesthetic management of caesarean section in women with long QT syndrome; the description of myocardial ventricular repolarisation in healthy women during caesarean delivery could be a first step. The aim of this study was to describe modification of the QT interval, corrected for heart rate, and the interval between the peak and the end of the T-wave (Tpeak-Tend interval) during caesarean section under spinal anaesthesia. We studied 40 patients scheduled for caesarean section under spinal anaesthesia. ⋯ Corrected QT and Tpeak-Tend intervals were unchanged from pre-operative values after induction of spinal anaesthesia, but increased significantly after oxytocin injection. The choice of vasopressor did not affect the Tpeak-Tend interval. The risk-benefit balance of oxytocin bolus during caesarean delivery should be discussed with women with a history of long QT syndrome.
