Abstract
Background: Emergence delirium in elderly patient continues to be a significant problem in the
post-anesthetic care environment interfering with patient recovery period and proving to be a
challenge to attending staffs.
Objective: To determine the incidence and associated factors of emergence delirium after
anesthesia in elderly patients at post anesthesia care unit in University of Gondar
Comprehensive Specialized Hospital, North West Ethiopia 2020.
Methods: An institution based cross-sectional study was conducted from February 20, to May
20, 2020 in University of Gondar Comprehensive Specialized Hospital, after ethical approval
taken from the review committee. A total of 172 elderly participants were included. Emergence
delirium was assessed by Richmond agitation sedation scale. Statistical analysis was done by
using statistical package for social sciences version 20.
Bivariable binary logistic regression analysis was performed to determine whether each of
independent variables was associated or not with the outcome variable. Only variables with pvalue less than 0.2 were entered into the multivariable binary logistic regression analysis. Both
Crude and Adjusted Odds Ratios with 95% CI were calculated to show strength of association.
Variables with P-value of <0.05 were considered to be statistically significant.
Result: In this study the incidence of emergence delirium after anesthesia in elderly patients at
post anesthesia care unit was 40.7% (95%CI: 32, 48). perioperative intravenous narcotic used,
(AOR:5.1,95%CI:1.265,20.565), intraoperative excessive blood loss (AOR:6.5,95%CI:
2.47,17.02), postoperative pain (AOR:3.9,95%CI:1.134,13.596), and preoperative anxiety
(AOR:7,95%CI:1.757,28.549), were significantly associated with emergence delirium after
anesthesia in elderly patients at post anesthesia care unit.
Conclusion and recommendation: In our study perioperative intravenous narcotic used,
intraoperative excessive blood loss, postoperative pain, and preoperative anxiety were
significantly associated with emergence delirium. Reassuring of patients preoperatively and gave
full information about anesthesia as well as the procedure and adequate post operative pain
management decreased the magnitude of emergence delirium
