Meta Analysis
[The menstruation cycle in the postoperative phase. Its effect of the incidence of nausea and vomiting].
Several studies suggest that the menstrual cycle has an impact on postoperative nausea and vomiting (PONV). However, many studies report inconsistent results. Thus, in this systematic review the results of all available studies are compared and statistically synthesised. ⋯ Studies investigating the influence of the menstrual cycle on the incidence of PONV show inconsistent results. Summarising the data of these studies suggests that the phase of the menstrual cycle has no impact on the occurrence of PONV.

Randomized Controlled Trial Comparative Study Clinical Trial
[Hemodynamic effects of spinal anesthesia with 2% lidocaine in comparison to 0.5% isobaric bupivacaine].
Our study compared the haemodynamic changes after spinal anesthesia with 2% lignocaine and 0.5% plain bupivacaine. ⋯ In patients developing a sensory block at or above the T6 dermatome, the decrease in cardiac output and mean arterial pressure in the first 25 min after spinal anaesthesia is smaller when 2% lignocaine rather than 0.5% bupivacaine is used for blockade.
