Psychometric properties of Iowa Anesthesia Satisfaction Scale Turkish version.

BACKGROUND: The Iowa Satisfaction with Anesthesia Scale (ISAS) is a valid and reliable measurement tool developed to evaluate patient satisfaction with anesthesia care during different surgical interventions. It is adapted to various languages and used in many studies. Considering the satisfaction of the patient with anesthesia applied in surgical procedures, the presence of such a measurement tool is crucial. AIM: From this point of view, the study aimed to evaluate psychometric properties of the ISAS by adapting it to Turkish culture. METHODS: In this study, a descriptive, methodological and cross-sectional design was used. A total of 210 patients who underwent surgery under general or regional anesthesia were in the study. RESULTS: ISAS Turkish version (ISAS-T) shows good reliability which is obvious with a Cronbach's alpha value of 0.80. The correlation levels of the items with the ISAS total score were calculated between .45 and .73. Test-retest reliability was calculated as 0.83. CFA analysis was applied to the one-dimensional 11-item final version of ISAS. The uni-dimensionality of the 11-item scale was confirmed on a Turkish patient sample. The fit indices for the model obtained were calculated as χ2/sd = 2.342, RMSEA = .80, SRMR = .04, CFI = .90, GFI = .92. The fit indices of the model have good and acceptable fit values. CONCLUSION: Based on the psychometric evaluation, ISAS-T is a valid and reliable measurement tool for measuring patient satisfaction with anesthesia applied during different surgical procedures.

The effect of body mass index on perioperative thermoregulation.

PURPOSE: We evaluated the effects of body mass index (BMI) on thermoregulation in obese patients scheduled to undergo laparoscopic abdominal surgery. METHODS: Sixty patients scheduled to undergo laparoscopic abdominal surgery with no pre-medication were included in the study. The patients were classified into 4 groups according to BMI <24.9, 25-39.9, 40-49.9, and >50. Anesthesia was provided with routine techniques. Tympanic and peripheral temperatures were recorded every 5 minutes starting with the induction of anesthesia. The mean skin temperature (MST), mean body temperature (MBT), vasoconstriction time, and vasoconstriction threshold that triggers core warming were calculated with the following formulas: MST = 0.3 (Tchest + Tarm) + 0.2 (Tthigh + Tcalf). MBT was calculated using the equation 0.64Tcore+0.36Tskin, and vasoconstriction was determined by calculating Tforearm-Tfinger. RESULTS: There was no significant difference between the groups in terms of age, gender, duration of operation, and room temperature. Compared to those with BMI <24.9, the tympanic temperature was significantly higher in those with BMI =25-39.9 in the 10th, 15th, 20th, and 50th minutes. In addition, BMI =40-49.9 in the 5th, 10th, 15th, 20th, 25th, 30th, 40th, 45th, 50th, and 55th minutes and BMI >50 in the 5th, 10th, 15th, 20th, 25th, 30th, 50th, and 55th minutes were less than those with BMI <24.9 (P<0.05). There was no significant difference in terms of MST and MBT. Vasoconstriction occurred later, and that vasoconstriction threshold was significantly higher in patients with higher BMIs. CONCLUSION: Under anesthesia, the core temperature was protected more easily in obese patients as compared to nonobese patients. Therefore, obesity decreases the negative effects of anesthesia on thermoregulation.
