ABSTRACT
Abstract Background: Postoperative nausea and vomiting is the second most common complaint in the postoperative period after pain. The incidence of postoperative nausea and vomiting was 60-80% in middle ear surgeries in the absence of antiemetic prophylaxis. Because of this high incidence of postoperative nausea and vomiting, we aimed to assess the effect of palonosetron-dexamethasone and ondansetron-dexamethasone combination for the prevention of postoperative nausea and vomiting in patients of middle ear surgery. Methods: Sixty-four patients, scheduled for middle ear surgery, were randomized into two groups to receive the palonosetron-dexamethasone and ondansetron-dexamethasone combination intravenously before induction of anesthesia. Anesthesia technique was standardized in all patients. Postoperatively, the incidences and severity of nausea and vomiting, the requirement of rescue antiemetic, side effects and patient satisfaction score were recorded. Results: Demographics were similar in the study groups. The incidence difference of nausea was statistically significant between groups O and P at a time interval of 2-6 hours only (p = 0.026). The incidence and severity of vomiting were not statistically significant between groups O and P during the whole study period. The overall incidence of postoperative nausea and vomiting (0-24 hours postoperatively) was 37.5% in group O and 9.4% in group P (p = 0.016). Absolute risk reduction with palonosetron-dexamethasone was 28%, the relative risk reduction was 75%, and the number-needed-to-treat was 4. The patient's satisfaction score was higher in group P than group O (p = 0.016). The frequency of rescue medication was more common in group O than in group P patients (p = 0.026). Conclusion: The combination of palonosetron-dexamethasone is superior to ondansetron-dexamethasone for the prevention of postoperative nausea and vomiting after middle ear surgeries.
Resumo Justificativa: Náusea e vômito no pós-operatório é a segunda queixa pós-operatória mais frequente após a dor. Sem profilaxia antiemética, a incidência de náusea e vômito no pós-operatório foi de 60−80% após cirurgia do ouvido médio. Dada a alta incidência relatada de náusea e vômito no pós-operatório, nosso objetivo foi avaliar o efeito da combinação de palonosetrona-dexametasona e ondansetrona-dexametasona na prevenção de náusea e vômito no pós-operatório em pacientes submetidos a cirurgia do ouvido médio. Método: Sessenta e quatro pacientes programados para cirurgia de ouvido médio foram aleatoriamente divididos em dois grupos. Um recebeu a combinação de palonosetrona-dexametasona (grupo P) e o outro ondansetrona-dexametasona (grupo O) por via intravenosa antes da indução anestésica. A técnica anestésica foi padronizada em todos os pacientes. No pós-operatório, foram registradas incidência e gravidade das náuseas e vômitos, necessidade de antiemético de resgate, efeitos colaterais e índice de satisfação dos pacientes. Resultados: As características demográficas foram semelhantes nos grupos estudados. A diferença na incidência de náusea foi estatisticamente significante entre os grupos O e P apenas no intervalo de tempo entre 2 e 6 horas (p = 0,026). A incidência e gravidade de vômito não foram estatisticamente significantes entre os grupos O e P durante todo o período do estudo. A incidência geral de náusea e vômito no pós-operatório (0−24 horas de pós-operatório) foi de 37,5% no grupo O e de 9,4% no grupo P (p = 0,016). A combinação palonosetrona-dexametasona associou-se com redução do risco absoluto de 28%, redução do risco relativo de 75%, e o número necessário para tratar foi 4. O escore de satisfação do paciente foi maior no grupo P (p = 0,016). A frequência da medicação de resgate foi mais comum no grupo O (p = 0,026). Conclusão: A combinação de palonosetrona-dexametasona é superior à ondansetrona-dexametasona na prevenção da náusea e vômito no pós-operatório após cirurgia de ouvido médio.

BACKGROUND: Catheter-related bladder discomfort (CRBD) is a frequent complaint after awakening from anesthesia in patients receiving perioperative bladder catheterization. Overactive bladder (OAB) and CRBD show similar symptoms; thus, drugs used for the management of OAB influence symptoms of CRBD. Trospium chloride has been found effective in managing resistant cases of OAB. We evaluated the efficacy of oral trospium on CRBD in the postoperative period. METHODS: Sixty-four male and female adult patients, with planned spinal surgery and requiring urinary bladder catheterization, were randomly divided into two groups of 32 each. Group T patients received 60 mg extended-release oral trospium (extended-release) 1 h before induction of anesthesia and Group C patients received a similar-looking placebo. The anesthetic technique was identical in both groups. The CRBD score was evaluated in the postoperative ward using a 4-point scale (1 = no discomfort, 2 = mild, 3 = moderate, 4 = severe). Readings were recorded on arrival (0 h), and 1 h, 2 h, and 6 h postoperatively. All patients received fentanyl for postoperative pain relief. RESULTS: The incidence of CRBD was significantly higher in group C than in group T at 0 h (66% vs 22%, P=0.001) and 1 h postoperatively (72% vs 28%, P=0.001). The incidence of moderate to severe CRBD was higher in group C at postoperative 2 h (82% vs 14%, P=0.004). There was no significant difference in postoperative fentanyl requirements. CONCLUSIONS: Pretreatment with 60 mg ER trospium reduced the incidence and severity of CRBD in the early postoperative period.
