Background and objectives: The objective of this report was to show the importance of pre-anesthetic assessment in reducing morbidity and mortality of surgical patients and alert to problems and anesthetic care associated with obstructive sleep apnea. Case report: This is a 28-year old male patient with class II obesity, sleep apnea, hypertension, referred to the pre-anesthetic outpatient clinic for evaluation of uvuloplasty under general anesthesia. After orientation on sleep apnea, explaining to the patient the risks associated with the procedure, and discussing with the surgeon, we decided to review the surgical indication and postpone the procedure. Conclusions: The pre-anesthetic outpatient clinic is extremely important in reducing morbidity as well as mortality of surgical patients and, especially, in evaluating patients with obstructive sleep apnea, showing to be fundamental for the anesthetic-surgical schedule, orienting conducts to be followed, and interfering positively on patient prognosis.

Surgery for craniosynostosis is associated with excessive blood loss, as well as morbidity and mortality risks. This study investigated the effectiveness of a surgical technique for nonsyndromic craniosynostosis intervention in controlling bleeding, assessed based on the volume of blood transfused. The cohort included 73 children who underwent nonsyndromic craniosynostosis surgery during a 3-year period. Retrospective evaluation of patient parameters included sex, weight, and age at the time of surgery; type of craniosynostosis; duration of surgery; hemoglobin concentration before and after surgery; rate of transfusion; and volume of transfused blood (mL/kg). The surgical technique involved skin incision and subgaleal dissection using electrocautery with a Colorado needle tip. The pericranium was not removed but instead kept in situ, and orbiectomy was performed using piezosurgery. Of the 73 children in the cohort, 75.3% underwent fronto-orbital advancement and were included in the analysis. The average age was 10.9 months (range: 4–96 months), with 68.5% boys and 31.5% girls (P < 0.001). The most common type of craniosynostosis was trigonocephaly (57.5%), followed by scaphocephaly (19.2%). The mean duration of the surgery was 2 hours and 55 minutes. Blood transfusion was needed in 56.2% of patients, with a mean volume of 8.7 mL/kg body weight transfused intraoperatively. No complications or fatalities were observed. These results suggested that meticulous, continuous control of homeostasis is paramount in minimizing blood loss during surgical repair of nonsyndromic craniosynostosis.

The pre-anesthetic outpatient clinic is extremely important in reducing morbidity as well as mortality of surgical patients and, especially, in evaluating patients with obstructive sleep apnea, showing to be fundamental for the anesthetic-surgical schedule, orienting conducts to be followed, and interfering positively on patient prognosis.

Complicações observadas: disritmias cardíacas sem repercussão hemodinâmica no intra-operatório (seis casos). Dois pacientes tiveram sangramento intra-operatório, mas somente um deles demandou implante de derivação ventricular externa. As complicações no pós-operatório foram: vômitos (6), picos febris (4) convulsões (2), laringoespasmo (1) e estridor laríngeo (1). CONCLUSÕES:A terceiro-ventriculostomia apresenta baixa incidência de complicações mesmo em pacientes com menos de 24 meses, desde que sejam adotadas técnicas anestésicas e cirúr-gicas adequadas.
