Abstract:
Objective:To explore the feasibility of the diameter of pupils during recovery period for predicting early postopera‐tive hypoxemia of patients undergoing gynecological laparoscopy with general anesthesia .Methods:A total of 70 adult female patients classified as I‐II according to American Society of Anesthesiologists(ASA)Criteria ,who underwent gynecological lapa‐roscopy during Oct 2013 and Dec 2013 ,were chosen .The operations were performed with total intravenous anesthesia .The di‐ameter of pupils upon arriving at postanesthesia care unit(PACU) .Patients were divided into two groups ,the group A (diame‐ter of pupil was <2 mm) and the group B (diameter of pupil was ≥2 mm) .The pulse oxygenation saturation(SpO2 ) immedi‐ately after inserting nasal catheter and 2 ,4 ,6 ,8 ,10 ,20 ,30 min after administering 3 L/min oxygen inhalation through nasal catheter ,were compared .Results:The value of SpO2 in group A was significantly lower than that in group B at 2 min and 4 min after arriving at PACU ,however ,the difference between two groups was not statistically significant at 6 min after arriving at PACU .The smaller the diameter of pupil on arriving at PACU was ,the lower the value of SpO2 at 2 min after arriving was , and there was a linear correlation between the two factors(r2 =0 .4268) .The area under receiver operator characteristic of the diameter of pupil for predicting the lowest value of SpO2 at 10 min after arriving at PACU was 0 .99 .It showed a very high ac‐curacy of the diameter of pupil for predicting postoperative hypoxemia .The threshold of the diameter of pupil for evaluation was 2 .25 mm .Its sensibility for predicting postoperative hypoxemia was 91 .4% ,and its specificity was 100% .Conclusions:The diameter of pupils during recovery period was correlated with the occurrence of early hypoxemia after general anesthesia . By checking the diameter of pupils upon arriving at PACU ,the monitoring on patients with sign of respiratory depression could be strengthened .
