Purpose: To investigate retrospectively the relation between anesthetic techniques, time of surgery and type of surgical resection in primary lung cancer. Methods: The anesthesia reports of 42 patients that had undergone surgery for lung cancer from January 2004 to September 2004 were analyzed. The patients' gender, tumor cytology, stage of tumor localization of the double lumen endotracheal tube, thoracotomy side, type of resection, time of anesthesia, single lung ventilation time, fluid, colloid fluid and blood transfusion were analyzed. Results: Patients who underwent lobectomy had a surgical anesthesia time of 235±84 minutes, whereas in patients who underwent pneumonectomy the mean value was 260±75 minutes. The difference between the two types of resection was not statistically significant (p > 0.05). Similarly, single lung ventilation time did not differ significantly (p > 0.05) between patients who underwent lobectomy (203 ± 79) and patients who underwent pneumonectomy (242 ± 75 minutes). The mean operation time of patients who received neoadjuvant chemotherapy was 228 ± 87.55 minutes, while patients who underwent primary surgical treatment had a mean value of 259 ± 66.48 minutes. There was no statistically significant difference between these two values (p > 0.05, (p = 0.317)). Conclusion: No statistically significant difference was found between type of resection, anesthesia, and surgical duration.
