Brief Summary

Study the effect of intraperitoneal instillation vs intravenous ondansetron on PONV added to intraperitoneal bupivacaine for enhanced recovery and to decrease incidence of PONV after laparoscopic surgeries.

Detailed Description

Laparoscopic surgeries have many advantages e.g., decreasing postoperative pain, better cosmetic, rapid recovery, and better recovery but also, it has side effects e.g., pain, postoperative nausea and vomiting.

There are many risk factors that cause PONV either patient related factors or anesthesia related factors (opioids, inhalational anesthetics, Nitrous oxide and duration of anesthesia) and surgery related factors (intraabdominal, laparoscopic, postoperative pain).

Intraperitoneal instillation of drugs can be used for instillation of LA, opoids, ketamine and antiemetics to provide analgesia and manage side effects of laparoscopic surgery. The mechanism of action of ondansetron is inhibition of presynaptic 5-HT3 receptors that located in the peripheral nervous. Study the effect of intraperitoneal instillation vs intravenous ondansetron on PONV added to intraperitoneal bupivacaine for enhanced recovery and to decrease incidence of PONV after laparoscopic surgeries.

Intraperitoneal instillation of ondansetron and bupivacaine (group A)Intraperitoneal instillation of ondansetron and bupivacainePatients will receive intraperitoneal instillation of (100 mg) 40 ml of bupivacaine 0.25 % and (4 mg) 2 ml ondansetron through abdominal ports by simple instillation technique before removal of trocars then clamping of abdominal drains for 1h to avoid drainage of LA.
Intravenous ondansetron and intraperitoneal instillation of bupivacaine (group B)Intravenous ondansetron and intraperitoneal instillation of bupivacainePatient will receive intravenous (4 mg) 2 ml ondansetron and intraperitoneal instillation of (100 mg) 40 ml of bupivacaine 0.25 % through abdominal ports by simple instillation technique before removal of trocars then clamping of abdominal drains for 1h to avoid drainage of LA.
Intraperitoneal instillation of bupivacaine (group C)Intraperitoneal instillation of bupivacainepatient will receive intraperitoneal instillation of (100 mg) 40 ml of bupivacaine 0.25 % through abdominal ports by simple instillation technique before removal of trocars then clamping of abdominal drains for 1h to avoid drainage of LA.
Primary Outcome Measures
NameTimeMethod
measure incidence of postoperative nausea and vomiting24 hours postoperative

The number of patient suffering from postoperative nausea and vomiting in each group

measure severity of postoperative nausea and vomiting24 hours postoperative

Simplified Postoperative Nausea and Vomiting Impact Scale (S-PNVIS)

1. \*Frequency of Nausea:\*

* 0: None

* 1: Occasionally (1-2 times a day)

* 2: Frequently (3-4 times a day)

* 3: Constantly (more than 4 times a day)

2. \*Frequency of Vomiting:\*

* 0: None

* 1: Once a day

* 2: 2-3 times a day

* 3: More than 3 times a day

3. \*Impact on Daily Activities:\*

* 0: No impact

* 1: Mild impact (able to perform most activities)

* 2: Moderate impact (some activities limited)

* 3: Severe impact (most activities limited)

#Scoring

* \*Total Score:\* Sum of scores from all 3 items.

* \*Interpretation:\* Higher total scores indicate a greater impact of nausea and vomiting on the patient recovery

Secondary Outcome Measures
NameTimeMethod
measure total numbers of rescue antiemeticall over 24 hours postoperative.

patients will receive 10 mg intravenous metoclopramide as rescue antiemetic immediately

Duration of hospital stay24 hours to 72 hours

time from PACU discharge till time to discharge home

postoperative pain by Numerical Rating Scale0 hour (basal) in PACU, 2, 4, 8, 12, 24 hours postoperative

10 cm line numbered from 0 to 10, patients instructed to circle the number that represents his/her pain intensity (0=no pain and 10=maximum pain)

total dose of rescue analgesia postoperative24 hours postoperative

total dose of diclofenac as rescue analgesia postoperative

Patient satisfaction24 hours postoperative

degree of satisfaction of the analgesia by using a 5-points Likert-like verbal scale (1 = very dissatisfied analgesia, 2 = dissatisfied analgesia, and 3 = neutral, 4=satisfied analgesia, and 5=very satisfied analgesia)
