Abstract

Context: Carbon dioxide is most commonly used to insufflate the abdominal cavity to facilitate short laparoscopic surgeries, where the real challenge lies in management of pathophysiological changes due to hypercarbia.

Aim: To study the effects of hypercarbia on respiration in short laparoscopic procedures such on diagnostic laparoscopy and laparoscopic sterilization.

Settings and Design: An observational study on 60 female subjects aged between 25-45 years presenting for diagnostic laparoscopy forinfertility, laparoscopic sterilization of ASA I & II category.

Methods and Material: Anaesthesia was given by ketofol Intravenous induction and sevoflurane 1% with CO 2/N2O insufflation of abdomen. The pre, intra, postoperative pulse, BP, O2 saturation, Respiratory rate, EtCO2 were noted with special reference to preinsufflation, during insufflation & deflation of abdomen.

Statistical analysis used: Descriptive analysis was carried out by mean and standard deviation and presented in trend line diagram, error  bar diagram for quantitative variables, frequency and proportion for categorical variables.

Results: Pre anesthesia Respiratory rate was 13.13±1.09. A1.75 time rise was noted in Respiratory rate (24.43±3.42) to maintainnormocarbia during insufflation.

Conclusions: Spontaneous Ventilation is effective in maintaining normocarbia during short laparoscopic procedures. Endotrachal intubation and paralysis to maintain normocarbia could be avoided.
