Although benign nerve sheath tumors have been described, primary tracheal schwannomas are extremely rare. We report a case of primary tracheal schwannoma, a rare benign nerve sheath tumor in a 58-year-old man with atypical symptoms of chronic cough, sputum and dyspnea for 2 months. Chest computerized tomography showed a 1.7 cm polypoid lesion in posterior wall of mid trachea. The results of bronchoscopic biopsy and immuno-histo-chemical studies were consistent with schwannoma. A surgical treatment of tumor resection and tracheal reconstruction by end-to-end anastomosis was performed.

Objectives

Propofol, midazolam and remifentanil are commonly used for clinical anesthesia. We compared the effects of midazolam-propofol-remifentanil and propofol-remifentanil on hemodynamic responses during anesthesia induction in hypertensive patients.

 Methods

Seventy-six hypertensive patients with ASA II-III were assigned to receive midazolam-propofol (group MP; n = 38) or propofol (group P; n = 38). Anesthesia was induced with midazolam 0.03 mg/kg (group MP) or saline 0.03 ml/kg (group P). After two minutes, propofol 1.0 mg/kg (group MP) or 1.5 mg/kg (group P) i.v. bolus was administered. Simultaneously, 4 ng/ml of remifentanil target controlled infusion (TCI) was administered in both groups. Anesthesia was maintained using sevoflurane and 2 ng/ml of remifentanil TCI. Systolic, diastolic, and mean blood pressure (SBP, DBP, and MBP) and heart rate (HR) were measured before induction, 2 min after midazolam or normal saline, 2 min after propofol, 1 min after rocuronium, and immediately, 1 min, 2 min, and 3 min after intubation.

 Results

SBP, DBP, and MBP decreased after propofol administration and increased immediately after intubation in both groups (P < 0.05). After intubation, SBP, DBP, and MBP decreased more than baseline values in either group. Although the overall BP of Group P was lower than that of Group MP, there were no significant differences except for SBP at 2min after intubation (P < 0.05). HR was no significant difference in either group.

 Conclusion

Our results suggest that midazolam-propofol-remifentanil has similar hemodynamic effect with propofol-remifentanil during anesthesia induction in hypertensive patients.
