To determine if the diagnostic fibrotic bronchoscopy by using LMA is safe comparing to bronchoscopy by using conscious sedation.
In this retrospective cohort study. We reviewed the operative records of 50 patients between the ages of 28 to 87 years who had diagnostic fiberotic bronchoscopic procedure at Cabell Huntington Hospital during the time period of 8/2007 to 5/2008. Patients were divided into two equal groups: Group A: 25 patients who had fibrotic bronchoscopy under conscious sedation anesthesia. Group B: 25 patients who had fibrotic bronchoscopy under general anesthesia by using LMA. We compare the two groups regarding the procedure total time, recovery time, and the complications during the procedure which include hypoxia and hypotension and after the procedure which include pneumothorax and bleeding.
The mean lengths of the procedure in the two groups were equal (25 minutes). The different types of the procedures which done during the procedure and the sedation medication doses (except for the anesthesia gas in group B) The mean patient age was similar between the two groups. There was no significant difference in the gender between the two groups, 32% of group A and 36% of group B were males.There was significant statically difference between the two groups in the mean length of the recovery time, (55 minutes) in group A and (106 minutes) in group B (P = 0.0004). The complications during the procedure in group B was (14%) which was significantly higher than group A (4%), (P = 0.017). however, the post procedure complication were similar between the two groups.
Patients who had diagnostic fibrotic bronchoscopy by using the LMA were likely to have more complications during the procedure and had longer of post operative recovery time as compare to the patients who had the same procedure under the conscious sedation anesthesia.
Using LMA for diagnostic fibrotic bronchoscopy should not be used routenly because of the increase risks of perioperative complications and the length of the recovery time.
