| Summary: | Background: The occurrence of postoperative nausea and
vomiting is generally associated with anesthesia and surgery.
The problem is compounded in cases of high-risk surgeries
where the incidence is quite high. The present study was
designed to compare the efficacy of Dexamethasone and
Ondansetron. Methods: This study was undertaken at the
Prathima Institute of Medical Sciences, Naganoor, Karimnagar.
In this randomized, open clinical trial, we studied 80 ASA grades
I to 1V patients of age group 20-60 years undergoing
Laparoscopic Laparotomy, Major Gynecological surgeries,
Renal, Shoulder and ENT surgeries under general anesthesia.
The patients were randomly divided into two groups, Group I
and Group II, each consisting of 80 patients. Group I received
4mg dexamethasone intravenous (IV) just after intubation and
group II received 4mg Ondansetron intravenous (IV), just before
extubation. Results: The most common age group was 50 – 59
years which had n=45(28.1%) patients out of which group I
was n=24(15%) patients and n=21(13.1%) patients. The next
common age group was 20 – 29 years out of which n=23
(14.4%) and n=18(11.2%). ondansetron group, early nausea is
mild in 6.9%, moderate in 3.8%, and severe in 1.2% of patients.
Whereas in the dexamethasone group early nausea is mild in
6.2%, moderate in 4.4%, severe in 1.9% of patients. In the
ondansetron group, late nausea is mild in 9.4%, moderate in
3.8%, and severe in 0.6% of patients. Whereas in the
dexamethasone group late nausea is mild in 7.5%, moderate
in 4.4%, severe in 0.6% of patients. In the ondansetron group,
early vomiting is mild in 5.0%, moderate in 0.6%, and severe in
0.6% of patients. Whereas in the dexamethasone group early
vomiting is mild in 4.4%, moderate in 1.2%, severe in 0.6% of
patients. Conclusion: dexamethasone given intravenously just
after intubation and ondansetron given intravenously just
before extubation are safe and have similar efficacy in postoperative nausea and vomiting after elective surgeries under
general anesthesia having a high risk of PONV |
