PurposeTo assess and compare the frequency of reflex sneezing occurring during periocular anesthetic injections with and without intravenous sedation.DesignRetrospective, comparative case series.MethodsSeven hundred and twenty-two patients undergoing oculoplastic surgical procedures were included in this study. Those who received a periocular anesthetic injection under intravenous sedation served as the test group of 381 subjects. Those who received a periocular anesthetic injection without intravenous sedation served as the control group of 341 subjects. The absence or presence of reflex sneezing in both groups was recorded and compared using Chi-square analysis.ResultsOf the 381 patients who received periocular anesthetic injections under intravenous sedation, 19 (5%) exhibited a vigorous sneeze. Conversely, none of the 341 patients who received periocular anesthetic injections without intravenous sedation sneezed (P < or = .001).ConclusionsSurgeons, anesthesia staff, and other operating room personnel should be aware of this unusual and potentially dangerous sneeze phenomenon when periocular anesthetic injections are delivered under intravenous sedation to reduce potential ocular complications.
