Since 1977, routine cul‐de‐sac insufflation to achieve a pneumoperitoneum for laparoscopy was performed on 350 women under local anesthesia. A van Schie/van Lith intrauterine tenaculum, used together with a self‐retaining Trelat speculum, guaranteed maximum stretching of the posterior vaginal fault and fixation of the anteflexed uterus necessary for an accurate 1‐cm deep penetration of a pneumoperitoneum needle into the cul‐de‐sac. The correct position of the tip of the needle was determined precisely by means of two manometers. The failure rate in the first study of 195 procedures was 3.6% and that in the following 155 cases was 1.9%. There were no serious operative complications. The authors recommend the cul‐de‐sac insufflation approach for inducing pneumoperitoneum as the technique of choice.

sound, light, and touch, have proved to be asymmetrical under certain c~nditions.')-~r Correlation has been found to exist between the initial head-turning responses of infants two days post-partum and maternal holding preference two to three weeks later.16 This could mean that right-holding is appropriate in normal newborns showing left-side preference in their behavioural reactions. In sick, premature, and/or separated newborns this could be a sign of disturbed neonatal behaviour, as the percentage of asymmetrical responses to stimuli increases. Maternal and paternal handedness has been shown to have no influence on side preference for holding newborns.1.3.sJ1 Whether the holder's handedness fits in with the infant's asymmetrical behaviour and is indirectly correlated with side preference, is currently under investigation in our unit.
