prevalence of anesthesia complications in orthopedic surgeries and its related factors

Background: the duration of surgery in orthopedic surgeries is often longer than one hour.therefore, these patients are at further risk of complications induced by general anesthesia.the present study aimed to determine the prevalence of anesthesia complications in orthopedicsurgeries and its related factors.methods: this cross-sectional study was performed on 400 patients undergoing orthopedicsurgery in shahid beheshti hospital of kashan province, iran, in 2020. the study subjectswere recruited by convenience sampling and included those who underwent general anesthesiafor elective surgery and were transferred to post-anesthesia care unit (pacu). the researchinstruments included a demographic questionnaire and a checklist for recording complications(shivering, pain, nausea, vomiting, & vital signs). the necessary data were recorded after thepatient was admitted to the pacu, as well as half an hour and one hour later. the obtaineddata were analyzed using the chi-squared test, independent samples t-test, one-way analysisof variance (anova), pearson correlation coefficient, and logistic regression analysis in spssv. 16.results: the present research results suggested that the most and least frequent complicationswere vomiting (91.8%) and changes in blood pressure (5%), respectively. gender wassignificantly associated with pain, nausea, and hypertension (p<0.05). the pearson correlationcoefficient data indicated a significant relationship between the duration of anesthesia and themean scores of shivering, pain, nausea, tachycardia, and tachypnea (p<0.05). there was alsoa significant relationship between the types of surgery and shivering, pain, blood pressure, andnausea (p<0.05). pulse rate was significantly associated with complete intravenous anesthesiaand the duration of anesthesia (p<0.05).conclusion: the relatively high incidence of post-anesthesia complications in orthopedicsurgeries indicates the significance of employing skilled personnel as well as using adequatemonitoring equipment at the pacu. such measures help to decrease mortality and morbidityamong patients, also save on hospital costs.
