A notable decrease in PONV has been observed with the use of 5-hydroxytryptamine type 3 receptor antagonists and glucocorticoids. Aim: This study aimed to evaluate the effectiveness of the combination of intravenous methylprednisolone and ondansetron with ramosetron alone in preventing PONV in patients undergoing middle-ear surgeries. Settings and Design: This was a prospective, randomized, double-blind study that comprised sixty patients in the age group of 18–60 years belonging to the American Society of Anesthesiologists (ASA) physical status classification I or II and undergoing middle-ear surgery. Materials and Methods: With the help of computer-generated randomization table, sixty patients in the age group of 18–60 years belonging to ASA physical status classification I or II and undergoing middle-ear surgery were randomly allotted to receive a combination of methylprednisolone 40 mg (given at the beginning of surgery) and ondansetron 4 mg (given near the end of surgery) (Group MO, n = 30) or ramosetron 0.3 mg (near the end of surgery) (Group R, n = 30). In both the groups, the incidence of PONV was studied. Statistical Analysis: Chi-square test or Fisher's exact test was utilized to analogize the categorical variables. Independent t-test was utilized to analogize the continuous variables. Results: In the first 2 h after the surgery, the difference between the two groups regarding the incidence of PONV was insignificant. Between 2 h and 24 h, the incidence of nausea was lowered significantly in the group MO compared to the group R (P = 0.01). Between 24 h and 48 h, the incidence of nausea was more in group R compared to the combination therapy group, which was statistically significant. Conclusion: The combination therapy is better than ramosetron alone for the prevention of PONV after middle-ear surgery. Therefore, we advocate a combination of methylprednisolone and ondansetron for prophylaxis for PONV in middle-ear surgeries.","PeriodicalId":7798,"journal":{"name":"Anesthesia, Essays and Researches","volume":"16 1","pages":"60-64"},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9558658/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"33516256","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Accelerated partial breast irradiation (APBI) is considered as an alternative to whole breast irradiation. The reasons are it requires less number of irradiation fractions, shorter treatment time, and decreased size of irradiation. The procedure includes insertion of several brachycatheters, which is associated with significant pain in the postoperative period. We report case series of 8 patients of APBI where perioperative pain management was done using ultrasound (USG)-guided serratus anterior plane (SAP) block with catheter insertion. The catheter was placed between the serratus anterior muscle and external intercostal muscle. The drug used was 0.4 mL.kg^-1 of 0.375% Ropivacaine with a maximum value of 30 mL. On the day of the procedure, all patients were given two boluses of ropivacaine 20 mL each at an interval of 6 h. From the next day onward, they received ropivacaine boluses on demand basis when Numerical Rating Scale (NRS) was >4. There were no complications during the procedure. None of the patients required extra fentanyl boluses intraoperatively. One patient did not have an SAP catheter inserted during primary insertion, as she failed to give consent for block. On repositioning of catheters, she experienced severe pain with a NRS of 8/10.
