RESUMO
Background Incidence of postoperative nausea and vomiting (PONV) in susceptible patients can be unacceptably high (70-80% reported incidence). This study was designed to evaluate the effect of palonosetron and ondansetron in preventing PONV in high-risk patients undergoing gynecological laparoscopic surgery. Methodology In this randomized, controlled, double-blind trial, non-smoking females aged 18-70 years, weighing 40-90 kg, and posted for elective laparoscopic gynecological surgeries were enrolled into ondansetron (Group A, n = 65) and palonosetron (Group B, n = 65) groups. Palonosetron (1 mcg/kg IV) or ondansetron (0.1 mg/kg IV) were administered just before induction. Postoperatively, the incidence of nausea, vomiting, PONV (scored on a scale of 0-3), need for rescue antiemetic, complete response, patient satisfaction, and adverse effects were evaluated up to 48 h following surgery. Normally distributed continuous variables were compared using Student's t-test. In addition, the Chi-squared test or Fisher's exact test were used to compare nominal categorical data as deemed appropriate. P-value <0.05 was observed as statistically significant. Results The overall PONV scores and postoperative nausea scores during 0-2 and 24-48 hours were comparable, but PONV scores (p = 0.023) and postoperative nausea scores (p = 0.010) during 2-24 hours were significantly lesser in Group B compared to Group A. There was no statistically significant difference in the postoperative vomiting score or retching during 0-48 hours. The amount of first-line rescue antiemetic used during 2-24 hours was significantly higher in Group A (56%) than in Group B (31%) (p = 0.012; p <0.05). A complete response to the drug during 2-24 hours was significantly higher (p = 0.023) in Group B (63%) compared to Group A (40%), whereas response was comparable during 0-2 and 24-48 hours. Both groups had a comparable incidence of adverse effects and patient satisfaction scores. Conclusion Palonosetron has a superior anti-nausea effect, less need for rescue antiemetics, and lesser incidence of total PONV compared to ondansetron during 2-24h and comparable effect to ondansetron during 0-2h and 24-48h postoperative period in high-risk patients undergoing gynecological laparoscopic surgery.
RESUMO
Background: Incidence of postoperative nausea and vomiting (PONV) in susceptible patients can be unacceptably high (70-80% reported incidence). This study was designed to evaluate the effect of palonosetron and ondansetron in preventing PONV in high-risk patients undergoing gynaecological laparoscopic surgery. Methodology: In this randomised, controlled, double-blind trial, nonsmoking females 18-70 years and weighing 40-90 kg, scheduled for elective laparoscopic gynaecological surgeries, were enrolled into the ondansetron (Group A, n=65) or palonosetron (Group B, n=65) group. Palonosetron (1 mcg/kg 4) or ondansetron (0.1 mg/kg 4) were administered just before induction. Postoperatively, incidence of nausea, vomiting, PONV (scored on a scale of 0-3), need for rescue antiemetic, complete response, patient satisfaction, and adverse effects were evaluated for up to 48 h following surgery. Results: The overall PONV scores and postoperative nausea score during 0-2 h and 24-48 h were comparable, but PONV scores (P=0.023) and postoperative nausea scores (P=0.010) during 2-24 h were significantly lesser in Group B compared to Group A. There was no statistically significant difference in the postoperative vomiting score or retching during 0-48 h. The amount of first-line rescue antiemetic used during 2-24 h was significantly higher in Group A (56%) than in Group B (31%) (P=0.012; P<0.05). Complete response to the drug during 2-24 h was significantly higher (P=0.023) in Group B (63%) compared to Group A (40%), whereas response was comparable during 0-2 h and 24-48 h. Both groups had comparable incidences of adverse effects and patient satisfaction scores. Conclusion: Palonosetron has superior antinausea effect, less need of rescue antiemetics, and lesser incidence of total PONV in comparison to ondansetron during 2-24 h and comparable effect to ondansetron during the 0-2 h and 24-48 h postoperative periods in high-risk patients undergoing gynaecological laparoscopic surgery.
RESUMO
A primigravida at 32 weeks of gestation presented to us with eclampsia and Posterior Reversible Encephalopathy Syndrome (PRES) along with SARS COVID-19 pneumonia. Immediate termination of pregnancy was done under general anesthesia and patient was electively ventilated in view of increased oxygen requirements. Further therapy using magnesium sulphate, antihypertensives, steroids, and convalescent plasma was carried out. The condition of the patient steadily improved leading to her extubation on the 4th postoperative day and subsequent discharge on the 8th day of admission.
