Do totally occlusive nasal packs after nasal surgery increase the risk of immediate respiratory distress during recovery from anesthesia?

Abstract

OBJECTIVES: This study aims to compare the risk of immediate respiratory distress (IRD) during the recovery of anesthesia between the nasal surgery with totally occlusive nasal packing and non-respiratory tract-related surgeries.PATIENTS AND METHODS: A total of 300 patients (180 males, 120 females; mean age 30.1±8.2 years; range 18 to 52 years) were included in the study. The patients were assigned to one of two age- and sex-matched groups according to surgery type: 1) patients undergoing nasal surgery with totally occlusive nasal packs for nasal septum deviation or 2) patients undergoing non-respiratory tract surgeries for various diseases. Immediate respiratory distress was defined as any unanticipated hypoxemia, hypoventilation or upper-airway obstruction (stridor or laryngospasm) requiring an active and specific intervention.RESULTS: The patients who underwent nasal surgery with totally occlusive nasal packs had a 6.25 times higher risk of IRD than the patients who underwent non-respiratory tract surgery during recovery from general anesthesia. Smokers had a 4.8 times higher risk of having IRD than non-smokers during the post-extubation phase. There were no significant differences in the incidence of IRD between males and females.CONCLUSION: Based on our study results, totally occlusive nasal packs and smoking were associated with poor extubation status at the end of the surgical procedure.
