Detailed Description

this study was done on 40 American Society of Anaesthesiologist(ASA) I & II live donors of either sex in adult age group undergoing laparoscopic live donor nephrectomy. After getting approval from institutes ethical committee and written informed consent, Donors were randomly allocated to either of two group. Anaesthesia was induced with injection morphine 0.1 mg/kg, injection propofol 1-2 mg/kg and vecuronium 0.1 mg/kg. Maintenance of anaesthesia was done with isoflurane and oxygen. After induction donors were placed into modified flank position with left side upward. Donors in Group A received Acetazolamide 5 mg/kg via orogastric tube soon after the induction of anaesthesia. Group S received saline as a placebo. investigator and subjects were blinded till the statistical analysis. Optic nerve sheath diameter was measured six times during perioperative periods by using high frequency ultrasound probe. Intra operative monitoring was done for Heart rate, Blood Pressure, pulse oximetry(Spo2), End Tidal Carbon Dioxide(ETCO2), Train Of Four(TOF) and Bi spectral index(BIS). Post operatively donors were reversed with injection neostigmine and glycopyrrolate.

once return of spontaneous ventilation was well established and patient becomes conscious oriented trachea was extubated and donors were shifted to post anaesthetic care unit(PACU). Postoperatively donors were monitored for Heart rate, Blood Pressure, Spo2, Comfort Score, Visual analog score for incisional site pain and shoulder tip pain, and Post operative nausea vomiting. Rescue analgesia was given to patients having comfort score less than 6.

After completion of study Optic nerve sheath diameter, pain scores and comfort scores was compared between both groups.
