title: [Research on correlation between anesthesia and complications of nasal endoscopic surgery].
abstract: OBJECTIVE
  To conclude the correlation between the alternatives of anesthesia--general and local anesthesia--and the complications of nasal endoscopic surgeries.
  
  
  METHODS
  Summing up the occurrence rates of the complications from 176 cases (321 sides) of patients with sinusitis(some were air crew); comparing and calculating these complications according to the ways of anesthesia which were adopted in the surgeries.
  
  
  RESULTS
  The occurrence rates of the complications from nasal endoscopic surgeries were 6.9% (22/321) and rates of major complications were 1.6% (5/321). Rates of 1.9% (4/210) occurred after surgeries with local anesthesia, 16.2% (18/111) with general anesthesia, which indicated the striking differences between them (chi2 = 21.11, P < 0.01). There were no differences between the types of diseases resulted from the choice of anesthesia (Type I and Type II, Type I and Type II, Type II and Type III chi2 = 0.06, 2.56, 3.82; P > 0.05). However, the incidences of various types of complications with local anesthesia were less than those with general anesthesia, which differed significantly within two groups (P < 0.05). No cases of obvious complications occurred to air crew.
  
  
  CONCLUSIONS
  The occurrence rates of complications of endoscopic surgeries with local anesthesia are lower than that of those with general anesthesia, which is worth promoting in ground crew and sing for reference to elevate rate of resuming flight in aircrew.
