RESUMO
A three-year observational study of patients undergoing tonsillectomy at the University Hospital of the West Indies was conducted to determine the incidence of postoperative vomiting. Data were collected to assess possible risk factors for vomiting as well as possible alleviating agents. Two hundred and fifty-two patients were included in the study and a thirteen per cent incidence of postoperative vomiting was found. This is significantly less than that quoted in other studies (40-73). Results also showed that steroids significantly reduced the incidence of postoperative vomiting in the study population. Muscle relaxants reversal agents and antibiotics particularly co-trimoxazole and ceftriaxone significantly increased its incidence. Usual antiemetic agents including dimenhydrinate (gravol) and promethazine (phenergan), as well as drugs known to possess antiemetic properties such as midazolam and propofol, lacked any significant protective effect against emesis. Opioid analgesia, inhalational induction and blood loss of greater than 10 of estimated blood volume appeared to increase emesis but failed to achieve statistical

significance:

RESUMEN
Un estudio de observación a pacientes de tonsilectomía en el Hospital Universitario de West Indies, fue realizado durante tres años, a fin de determinar la incidencia de vómitos post-operatorios. Se recogieron datos con el propósito de evaluar los posibles factores de riesgo por vómitos así como los posibles agentes para aliviarlos. Doscientos cincuenta y dos pacientes fueron incluidos en el estudio y se halló una incidencia de trece por ciento de vómitos post-operatorios. Esta cifra es significativamente menor que las citadas en otros estudios (40-73%). Los resultados también mostraron que los esteroides redujeron significativamente la incidencia de vómitos post-operatorios en la población del estudio. Los agentes de reversión de los relajantes musculares y los antibióticos co-trimoxazol y ceftriaxona aumentaron significativamente la incidencia. Los agentes antieméticos usuales, incluyendo incluso el dimenhidrinato (gravol) y la prometazina (fenergan), así como drogas conocidas por sus propiedades antieméticas, tales como el midazolam y el propofol, no mostraron efecto significativo alguno de protección contra la émesis. La analgesia opioide, la inducción por inhalación, y la pérdida de sangre mayor al 10% del volumen de sangre estimada, parecían aumentar la émesis, pero no alcanzaron a tener importancia estadística.
