Conditions

Health Condition 1: null- posted for laparoscopic cholecystectomy

Interventions

Intervention1: Low pressure group (L): Inclusion and exclusion criteria will be as described above. Laparoscopic cholecystectomy will be performed after insufflation of the abdomen with pressures 8-10

Eligibility

Inclusion criteria

Inclusion criteria: Patients in Group S will undergo laparoscopic cholecystectomy using standard (12-16 mm Hg) pressures whereas patients in Group L will undergo laparoscopy under low pressures (8-10 mm Hg). Patients aged 18-80 years and belonging to ASA I-III will be included.

Exclusion criteria

Exclusion criteria: We will exclude patients with orbital trauma as optic sonography in such patients is technically difficult
