RESUMEN

BACKGROUND AND OBJECTIVES: Acetylcholinesterase inhibitors may cause postoperative residual curarization when they are used for reversal of neuromuscular blockade. Sugammadex reverses neuromuscular blockade by chemical encapsulation and is not associated with the side effects that may occur with the use of anticholinesterase agents. Because of increased outpatient surgical procedures postoperative residual curarization and rapid postoperative recovery have a greater importance in the pediatric patient population. The aim of this study was to compare the efficacy of sugammadex and neostigmine on reversing neuromuscular blockade in pediatric patients undergoing outpatient surgical procedures. METHODS: 80 patients, aged 2-12 years, scheduled for outpatient surgery were enrolled in this randomized prospective study. Neuromuscular blockade was achieved with 0.6mgkg(-1) rocuronium and monitorized with train-of-four. Group RN (n=40) received 0.03mgkg(-1) neostigmine, Group RS (n=40) received 2mgkg(-1) sugammadex for reversal of rocuronium. Extubation time (time from the reversal of neuromuscular blockade to extubation), train-of-four ratio during this time, time to reach train-of-four>0.9, and probable complications were recorded. RESULTS: There was no significant difference between the patients' characteristics. Extubation time and time to reach train-of-four>0.9 were significantly higher in Group RN (p=0.001, p=0.002). Train-of-four at the time of neostigmine/sugammadex injection in Group RN were significantly higher than in the RS group (p=0.020). Extubation train-of-four ratio was significantly lower in Group RN (p=0.002). CONCLUSION: Sugammadex provides safer extubation with a shorter recovery time than neostigmine in pediatric patients undergoing outpatient surgical procedures.

RESUMEN

BACKGROUND AND OBJECTIVES: In laparoscopic surgical procedures, experts recommend tracheal intubation for airway management. Laryngeal mask airway (LMA) can be a good alternative to intubation. In this case series, we aimed to examine the use of the Supreme™ LMA (SLMA) in laparoscopic surgical practice. METHODS: We planned the study for sixty patients between the ages of 18 and 60, who would undergo laparoscopic surgery. We recorded one, 15, 30, 45, and 60-minute peripheral O2 saturation (SpO2) and end-tidal carbon dioxide (EtCO2) values, heart rate and mean arterial blood pressure (MAP). We observed the duration of SLMA insertion, the rate of gastric tube applicability, whether nausea, vomiting, and coughing developed, and whether there was postoperative 1-hour sore throat. RESULTS: The initial EtCO2 mean was lower than the EtCO2 means of 15, 30, 45, and 60 minutes (p < 0.0001) and the 15-minute EtCO2 mean was lower than other measured EtCO2 means. We observed the initial heart rate mean to be higher than the ones following the SLMA insertion, prior to the SLMA removal, and after the SLMA removal. The heart rate mean after the SLMA insertion was remarkably lower than the heart rate mean prior to the SLMA removal (p=0.013). The MAP after the SLMA insertion was lower than the initial MAP means, as well as the MAP averages prior to after the removal of SLMA (p=0.0001). CONCLUSION: SLMA can be a suitable alternative to intubation in laparoscopic surgical procedures in a group of selected patients.

RESUMEN

Justificativa e objetivo: especialistas recomendam a intubação traqueal para o manejo das vias aéreas em procedimentos cirúrgicos laparoscópicos. A máscara laríngea (ML) pode ser uma boa opção à intubação endotraqueal. Nesta série de casos, o nosso objetivo foi analisar o uso damáscara laríngea SupremeTM (MLS) na prática cirúrgica laparoscópica. Métodos: o estudo foi conduzido com 60 pacientes, entre 18 e 60 anos, submetidos à cirurgia laparoscópica. Os valores de saturação periférica de O2 (SpO2) e dióxido de carbono no fim da expiração (EtCO2) foram registrados nos minutos um, 15, 30, 45 e 60. A frequência cardíaca e a pressão arterial média (PAM) dos pacientes também foram registradas. Consideramos o tempo de inserção da MLS; a taxa de aplicabilidade da sonda gástrica; a ocorrência de náusea, vômito, tosse e dor de garganta uma hora após a cirurgia. Resultados: a média inicial de EtCO2 foi menor do que aos 15, 30, 45 e 60 minutos (p < 0,0001) e a média de EtCO2 aos 15 minutos foi menor do que nos outros tempos registrados. Observamos que a frequência cardíaca média inicial foi maior do que as subsequentes à inserção da MLS e as anteriores e posteriores à remoção da MLS. A frequência cardíaca média após a inserção da MLS foi acentuadamente menor do que a anterior à remoção da MLS (p = 0,013). A PAM após a inserção da MLS foi menor do que a inicial e também menor do que as anteriores à remoção da MLS (p = 0,0001). Conclusão: a MLS pode ser uma opção adequada para intubação em procedimentos cirúrgicos laparoscópicos em um grupo seleto de pacientes. .

RESUMEN

EXPERIÊNCIA E OBJETIVOS: A via aérea por máscara laríngea (LMA), que tem sido utilizada frequentemente no tratamento das vias aéreas, pode causar lesão e morbidade na área laringofaríngea. Nesse estudo, comparamos as alterações macroscópicas nas estruturas laringofaríngeas e a morbidade laringofaríngea pós-operatória pelo uso da LMA Supreme® versus LMA ProSeal® em crianças. MÉTODOS: Dividimos os pacientes em dois grupos. Inserimos LMA ProSeal #3 no primeiro grupo e LMA Supreme #3 no segundo grupo. Antes da inserção da LMA e em seguida à sua remoção, fizemos laringoscopia direta nos pacientes. Comparamos entre os dois grupos: hiperemia, lesão de mucosa e as manchas de sangue por ocasião da remoção da LMA, e também o tempo de inserção, percentual de sucesso na inserção do tubo gástrico na primeira tentativa, náusea, vômito e dor de garganta. RESULTADOS: Não foram observadas diferenças significativas entre os dois grupos para tempo médio de operação, gênero, idade, peso, percentual de sucesso na inserção do tubo gástrico na primeira tentativa, náusea, vômito, dor de garganta e lesão de mucosa. O tempo médio de inserção para o grupo LMA ProSeal foi significativamente maior versus grupo LMA Supreme (p = 0,0001). O índice de manchas de sangue na remoção da LMA foi significativamente mais alto no grupo LMA ProSeal versus LMA Supreme (p = 0,034). Os pacientes que apresentaram manchas de sangue por ocasião da remoção da LMA exibiram hiperemia e lesão de mucosa significativamente mais expressivas versus pacientes com LMA limpa (p = 0,0001, p = 0,020). CONCLUSÃO: Em crianças, a inserção da LMA Supreme é mais rápida e fácil do que a inserção da LMA ProSeal; e, em comparação com LMA ProSeal, causa menos lesão laringofaríngea.

In this trial, we compare the macroscopic changes on laryngopharyngeal structures and the postoperative laryngopharyngeal morbidity by using LMA supreme with LMA proseal in children. METHODS: We divided patients into two groups. We inserted size three LMA proseal into the first group and size three LMA supreme into the second group. Before LMA insertion and after LMA removal, we performed direct laryngoscopy on the patients. We compared hyperemia, mucosal injury and blood staining on LMA removal, as well as insertion time, rate of success in gastric tube insertion on the first attempt, nausea, vomiting, and sore throat between the two groups. RESULTS: We recorded no significant differences between the two groups for mean operation time, sex, age, weight, rate of success in gastric tube insertion on first attempt, nausea, vomiting, sore throat and mucosal injury. Mean insertion time for the LMA proseal group was significantly longer than the LMA supreme group (p = 0.0001). The ratio of blood staining on LMA removal was significantly higher in the LMA proseal group than the LMA supreme group (p = 0.034). The patients with blood staining on LMA removal exhibited significantly more mucosal hyperemia and injury than the patients with clear LMA (p = 0.0001, p = 0.020). CONCLUSION: LMA supreme insertion is faster and easier than LMA proseal and causes less laryngopharyngeal injury than LMA proseal in children.

RESUMEN

BACKGROUND AND OBJECTIVES: Sedation-analgesia is recommended for comfortable colonoscopy procedures, which are invasive and can be painful. This study aimed to compare the combinations of propofol-alfentanil and propofol-fentanyl for sedation-analgesia in elective colonoscopy patients. METHODS: This prospective and randomized study was planned in ASA I-II groups and included 80 patients between the ages of 18 and 65 years. Sedation-analgesia induction was performed as 1 µg.kg-1 fentanyl, 1 mg.kg-1 propofol in the propofol-fentanyl group (Group PF) and 10 µg.kg-1 alfentanil, 1 mg.kg-1 propofol in the propofol-alfentanil group (Group PA). Patients' scores were limited to 3-4 values on the Ramsey Sedation Scale (RSS) by 0.5 mg.kg-1 bolus additional doses of propofol in sedation-analgesia maintenance. We recorded demographical data, heart rate, mean arterial pressure (MAP), oxygen saturation of hemoglobin (SpO2), RSS value, colonoscopy time, total dose of propofol, complications, recovery time, and discharge time, as well as colonoscopist and patient satisfaction scores. RESULTS: MAP at the 15th minute in Group PA was signifi cantly higher than in Group PF (p = 0.037). Group PA's beginning mean heart rate was higher than the mean heart rate at subsequent readings (p = 0.012, p = 0.002). The mean total propofol dose of Group PA was signifi cantly higher than the total dose of Group PF (p = 0.028). The mean recovery time of Group PA was signifi cantly longer than that of Group PF (p = 0.032). CONCLUSION: Fentanyl provides better operative conditions and reduces the need for additional propofol doses. These advantages cause a shorter recovery time. Therefore, propofol-fentanyl is superior to the propofol-alfentanil for sedation-analgesia in colonoscopy.

RESULTADOS: A PAM aos 15 minutos no Grupo PA foi significativamente maior do que no Grupo PF (p = 0,037). A frequência cardíaca média do grupo PA foi maior no início do que nas mensurações subsequentes (p = 0,012, p = 0,002). A média da dose total de propofol do Grupo PA foi significativamente maior do que a do Grupo PF (p = 0,028). O tempo médio de recuperação do grupo PA foi significativamente maior do que o do grupo PF (p = 0,032). CONCLUSÃO: Fentanil proporciona melhores condições de operação e reduz a necessidade de doses adicionais de propofol. Essas vantagens diminuem o tempo de recuperação. Portanto, propofol-fentanil é superior ao propofol-alfentanil para sedação e analgesia em colonoscopia.
