Clinical Study Gastric Decompression Decreases Postoperative Nausea and Vomiting in ENT Surgery

There is a passive blood flow to the stomach during oral and nasal surgery. It may cause postoperative nausea and vomiting (PONV). We researched the relationship between gastric decompression (GD) and severity of PONV in ear, nose, and throat (ENT) surgery. 137 patients who have been into ENT surgery were included in the study. In Group I ( = 70), patients received GD after surgery before extubation; patients in Group II ( = 67) did not receive GD. In postoperative 2nd, 4th, 8th, and 12th hours, the number and ratio of patients demonstrating PONV were detected to be significantly more in Group II as compared to Group I. PONV was also significantly more severe in Group II as compared to Group I. In Group I, the PONV ratio in the 2nd hour was significantly more for those whose amounts of stomach content aspired were more than 10 mL as compared to those whose stomach content aspired was less than 10 mL. In the 4th, 8th, and 24th hours, there is no statistically significant difference between the stomach content aspired and PONV ratio. GD reduces the incidence and severity of PONV in ENT surgery

A reinserção do estilete não afeta a incidência de cefaleia pós-punção dural (CPPD) após raquianestesia La reinserción del estilete no afecta la incidencia de cefalea pos punción dural (CPPD) posteriormente a la raquianestesia Reinsertion of the stylet does not affect incidence of post dural puncture headaches (PDPH) after spinal anesthesia

JUSTIFICATIVA E OBJETIVOS: Este estudo foi conduzido para investigar os efeitos da reinserção do estilete em cefaleia pós-punção dural (CPPD) após raquianestesia. MÉTODOS: Foram selecionados para este estudo 630 pacientes submetidos a cirurgia eletiva com raquianestesia. Os pacientes foram randomicamente designados para dois grupos: Grupo A (reinserção do estilete antes da retirada da agulha) e Grupo B (retirada da agulha sem reinserção do estilete). Os pacientes foram observados durante 24 horas no hospital e avaliados quanto à CPPD no terceiro e sétimo dias do estudo. RESULTADOS: No geral, a incidência da CPPD foi de 10,8% (68 pacientes). Trinta e três desses pacientes (10,5%) que estavam no Grupo A e 35 (11,1%) no grupo B tiveram CPPD. Não houve diferença significativa entre os dois grupos em relação à CPPD. CONCLUSÕES: Ao contrário da punção lombar diagnóstica, a reinserção do estilete após raquianestesia com agulhas tipo Quincke de calibre 25 não reduz a incidência de CPPD.JUSTIFICATIVA Y OBJETIVOS: Este estudio fue hecho para investigar los efectos de la reinserción del estilete en la cefalea pos punción dural (CPPD) después de la raquianestesia. MÉTODOS: Un total de 639 pacientes sometidos a la cirugía electiva con raquianestesia se seleccionaron para este estudio. Los pacientes fueron aleatoriamente designados para dos grupos: Grupo A (reinserción del estilete antes de la retirada de la aguja) y Grupo B (retirada de la aguja sin la reinserción del estilete). Los pacientes fueron observados durante 24 horas en el hospital y evaluados CPPD en el tercero y en el séptimo día del estudio. RESULTADOS: En general, la incidencia de CPPD fue de un 10,8% (68 pacientes). Treinta y tres de ellos (10,5%) que estaban en el Grupo A (reinserción del estilete antes de la retirada de la aguja) y 35 (11,1%) en el grupo B (retirada de la aguja sin la reinserción del estilete) tuvieron CPPD. No hubo diferencia significativa entre los dos grupos con relación a la CPPD. CONCLUSIONES: Al contrario de la punción lumbar diagnóstica, la reinserción del estilete posterior a la raquianestesia con agujas tipo Quincke de calibre 25 no reduce la incidencia de CPPD.BACKGROUND AND OBJECTIVES: This study was conducted to investigate the effects of reinsertion of the stylet after a spinal anesthesia procedure on the Post Dural Puncture Headache (PDPH). METHODS: We have enrolled into this study 630 patients who were undergoing elective operations with spinal anesthesia and randomized them to Group A (stylet replacement before needle removal) and Group B (needle removal without stylet replacement). These patients were observed for the duration of 24 hours in the hospital and they were checked for PDPH on the 3rd and the 7th day of the study. RESULTS: Overall, the PDPH incidence was at 10.8% (68 patients). Thirty-three of these patients (10.5%) who were in Group A (stylet replacement before needle removal) and the other 35 patients (11.1%) who were in Group B (needle removal without stylet replacement) experienced PDPH. There was no significant difference between the two groups with respect to the PDPH. CONCLUSIONS: In contrary to the diagnostic lumbar puncture, reinsertion of the stylet after spinal anesthesia with 25-gauge Quincke needles does not reduce the incidence of PDPH

Comparison of Intra-operative Pressure-Controlled Ventilation and Volume-Controlled Ventilation in Bariatric Surgery: A Prospective Randomized Study

Background: Mechanical ventilation may be particularly challenging in obese patients undergoing laparoscopic bariatric surgery. The present study aimed to compare the effects of pressure-controlled ventilation (PCV) with those of volume-controlled ventilation (VCV) on peripheral tissue oxygenation (PTO), respiratory function, hemodynamic status, and ventilation-related complications in patients undergoing laparoscopic bariatric surgery

PONV was also significantly more severe in Group II as compared to Group I. In Group I, the PONV ratio in the 2nd hour was significantly more for those whose amounts of stomach content aspired were more than 10 mL as compared to those whose stomach content aspired was less than 10 mL. In the 4th, 8th, and 24th hours, there is no statistically significant difference between the stomach content aspired and PONV ratio. GD reduces the incidence and severity of PONV in ENT surgery
