On the night before the surgery, she was given tablet ranitidine 150mg and tablet alprazolam 0.5mg, as per our routine protocol. On the day of surgery, she was wheeled to the operation theater, her intravenous line was put and ringer lactate infusion was started. Monitoring included 5-lead electrocardiography, pulse oximetry, non-invasive blood pressure and end-tidal carbondi-oxide concentration. She was premedicated with injection glycopyrrolate 0.2mg, injection ondansetron 4mg and injection fentanyl 100μm intravenous. She was induced with injection propofol 100mg and injection vecuronium 0.8mg intravenous, followed by intubation with 7.5mm endotracheal tube. 16F nasogastric tube was put nasally. After confirming the position, surgery was allowed to start. Maintenance of anaesthesia was done with oxygen:nitrous (50:50), isoflourane and intravenous vecuronium injection. Intra-peritoneal insufflation was done using carbon-di-oxide gas and intra-abdominal pressure was maintained at around 12mmHg. Towards the end of surgery which lasted for 60minutes, injection diclofenac 75mg infusion was started. Patient was reversed with injection neostigmine 2.5mg and injection glycopyrrolate 0.4mg.
