Effects of acute carbon monoxide poisoning on the P-wave and QT interval dispersions.

Objective: The aim of our study was to investigate atrial conduction and ventricular repolarization inhomogeneities using P-wave dispersion (Pwd) and QT dispersion (QTd) analyses in acute carbon monoxide (CO) poisoning.

Methods: Sixty patients were retrospectively included in this case-controlled study. Thirty acute CO poisoning patients were assigned to the Group with acute CO poisoning (ACOP).

Brief report: the effects of the menstrual cycle on the hemodynamic response to laryngoscopy and tracheal intubation.

We designed this study to determine the effect of the menstrual cycle on the hemodynamic response to tracheal intubation (TI). Sixty-two ASA I women who were either in the follicular phase (group F, n = 31) or luteal phase (group L, n = 31) of their menstrual cycle were included in the study. Patients received propofol and rocuronium for intubation.

Effect of menstrual cycle on the injection pain due to propofol.

Background: This prospective, double-blind and randomized study is designed to determine the effect of menstrual cycle on the injection pain of propofol.

Methods: Seventy-two patients scheduled for elective surgery under general anaesthesia were divided into two groups according to the phase of the menstrual cycle. Patients were at follicular phase (Pd 8-12) in Group F (n = 36) and luteal phase (Pd 20-24) in Group L (n = 36).
