Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study is designed to compare the effects of a single dose Ondansetron 4mg versus Palonosetron 75mcg in the prophylaxis against early \& delayed postoperative nausea and vomiting in the first 48 hours post-operatively in patients undergoing Endoscopic Retrograde Cholangio-Pancreatography (ERCP) to determine the complete response, complete control and failure rates.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Premedication will be omitted. Pre-operative baseline values of heart rate and blood pressure will be recorded. On arrival in the operation theatre, the routine monitoring devices (ECG, Pulse Oximetry \& Non Invasive Blood Pressure) will be applied and base line heart rate, blood pressure (Systolic, diastolic and mean arterial blood pressure) and arterial Oxygen saturation will be recorded.

After an intravenous line is secured, while pre-oxygenating the patient. Anaesthesia will be induced using fentanyl 1-2 µg/kg and sodium propofol 1.5-2.5 mg/kg according to the patient general condition and hemodynamics and intubation will be facilitated by using atracurium besylate 0.5mg/kg.

Anaesthesia will be maintained with O2 in air (50%), sevoflurane (0.8-1.0 MAC). Muscle relaxation will be maintained with boluses of atracurium besylate 0.1 mg/kg. Intermittent positive pressure ventilation will be adjusted to maintain end tidal carbon dioxide between 30-35mm Hg. Intravenous crystalloids (3-4 ml/kg/hr) will infused during intra-operative and immediate post-operative period. Intra-operatively, the following parameters will be monitored: ECG, blood pressure, pulse rate, end tidal carbon dioxide (ET CO2) \& oxygen saturation (SpO2). Diclofenac sodium 1mg/kg intramuscularly to protect against Post ERCP Pancreatitis \& Paracetamol (1gm) intravenously will be administered 15 minutes before the end of procedure followed by the administration of the anti-emetic prophylaxis according to group allocation.

At the end, residual neuromuscular block will be antagonized using atropine and neostigmine and trachea will be extubated after signs of adequate neuro-muscular reversal are achieved. After extubation, patients will be transferred to the Post anaesthesia care unit where the blood pressure, heart rate, respiratory rate and O2 saturation will be monitored continuously every five minutes for 60 minutes.

If Visual Analogue Score (VAS) score is ≥3, rescue analgesia will be provided with Pethidine in 10mg increments / 5minutes until the VAS score is less than 3.

Pain intensity will be assessed using VAS for the first 24 hours. Post-operative pain relief will be provided Paracetamol (1gm) intravenously given regularly every 8 hours for the first 24 hours.

Any incidence of nausea, retching or vomiting and use of any rescue medication during the first 24 hours at time interval of 0, 1/2, 1, 2, 6,12, 24 and 48 h will be noted, Nausea is defined as the subjective sensation of an urge to vomit, in the absence of expulsive muscular movements. Retching is defined as an unproductive effort to vomit. Vomiting is defined as the forcible expulsion of the gastric contents through the mouth. Retching and vomiting will be collectively termed emetic episodes.

Rescue anti-emetic therapy in the form of Metoclopramide 10 mg intravenously will be provided for any patient suffering from an emetic episode as described above. The use of antiemetic rescue medication will be recorded \& analysed.

Patients will stay at the hospital post ERCP according to the discretion of the treating physician opinion, if any patient will be discharged before 48 hours, the data will be collected by telephone.
