Immunotherapeutic Properties of Dexmedetomidine on Pain Management and Cardiovascular Function in Videolaparoscopic Cholecystectomies: A Randomized, Two-Arm, Double-Blinded, Placebo-Controlled Trial.

BACKGROUND: Laparoscopy represented one of the most innovative surgical techniques approached in the surgery field. Dexmedetomidine association with general anesthesia promotes the response control to trauma by altering the neuroinflammatory reflex, provides better clinical outcomes in the postoperative period and reduces the excessive use of drugs with risk for addiction. This trial aims to evaluate the potential drug treatment of dexmedetomidine on organic function, with the targets in neuroinflammation, perioperative pain control and blood pressure measurements in a medium-sized surgical model. METHODS: Fifty-two patients were randomized in two groups: Sevoflurane and Dexmedetomidine - A (dexmedetomidine infusion [1 µg/kg loading, .2-.5 µg/kg/h thereafter]) vs Sevoflurane and Saline .9% - B. Three blood samples were collected at three times: before surgery, 4 to 6 hours after surgery and 24 hours postoperatively. The primary outcome was inflammatory and endocrine mediators dosage analisys. Finally, we evaluated pain and opioid use as secondary outcomes, also the hemodynamic values. RESULTS: In Dexmedetomidine group A, a reduction of Interleukin 6 was found during 4-6 hours after surgery. A reduction of IL-10 was noted in the measurement of its values 24 hours after the procedure, with statistical significance. Also, systolic and diastolic blood pressure, as well heart rate were attenuated, and there was a lower incidence of pain and opioid consumption in the first postoperative hour (P < .0001) in the anesthetic recovery room. CONCLUSIONS: Dexmedetomidine provided anti-inflammatory activity, sympatholytic effect and analgesia with cardiovascular safety. It reinforces the therapeutic nature of highly selective α2-adrenergic agonists when combined within anesthetic interventions.

Avaliação da qualidade de vida de pacientes portadores de hiperidrose primária submetidos à simpatectomia videotoracoscópica / Evaluation of the quality of life of patients with primary hyperhidrosis submitted to videothoracoscopic sympathectomy

RESUMO Objetivo: avaliar a qualidade de vida de pacientes submetidos à simpatectomia por videotoracoscopia para tratamento de hiperidrose primária. Métodos: foram avaliados os pacientes submetidos à simpatectomia por videotoracoscopia para tratamento de hiperidrose primária pela equipe de cirurgia torácica do Hospital Universitário Gafrée e Guinle-UNIRIO entre julho de 2004 e agosto de 2013. Foi aplicado um questionário sobre qualidade de vida relacionada à hiperidrose desde o pré-operatório até um ano após a operação. Resultados: o questionário foi aplicado em 122 pacientes com média de idade de 25 anos, sendo 57% mulheres. Quanto à severidade da hiperidrose primária, 83% dos pacientes referiam como pouco tolerável ou intolerável, associada com grande limitação da qualidade de vida, sendo esta pobre ou muito pobre em 82% dos casos. No pós operatório a hiperidrose compensatória ocorreu em 78% dos pacientes, entretanto foi considerada como imperceptível ou pouco perceptível por 85% destes pacientes, classificando-a como aceitável. Em 15% dos pacientes a hiperidrose compensatória foi classificada como perturbadora. Conclusão: a simpatectomia videotoracoscópica melhora a qualidade de vida dos pacientes com hiperidrose primária. A hiperidrose compensatória transitória ocorreu na maioria dos pacientes, mas não alterou de maneira significativa a melhora da qualidade de vida.

ABSTRACT Objective: to evaluate the quality of life of patients undergoing video-assisted thoracoscopy for primary hyperhidrosis. Methods: we evaluated the patients who underwent thoracoscopic sympathectomy to treat primary hyperhidrosis by the team of thoracic surgery at the University Hospital Gaffrée and Guinle - UNIRIO between July 2004 and August 2013. It was applied a questionnaire about quality of life related to hyperhidrosis since preoperative period until one year after the surgery. Results: one hundred twenty two patients answered the questionnaire, with a mean age of 25 years, 57% of whom were women. In relation to severity of primary hyperhidrosis, 83% of the patients reported as tolerable or somewhat tolerable associated with major limitation of quality of life, which it was poor or very poor in 82% of cases. Postoperative compensatory hyperhidrosis occurred in 78% of patients, but it was regarded as invisible or barely noticeable for 85% of these patients, classifying it as acceptable. In 15% of patients, the compensatory sweating was classified as disruptive. Conclusion: thoracoscopic sympathectomy improves the quality of life of patients with primary hyperhidrosis. The transitional compensatory hyperhidrosis occurred in most patients, but did not improve significantly the quality of life.
