Background: As an anesthesia induced during cesarean section, spinal anesthesia is preferred over general and epidural anesthesia. This study aimed to review the trend of anesthetic methods for cesarean section based on data obtained from the Korean Health Insurance Review and Assessment Service from 2013 to 2018.Methods: The anesthetic methods were analyzed in 753,285 parturients who underwent a cesarean section in Korea from 2013 to 2018. We determined the association between each anesthetic method and hospital type and maternal and fetal factors. We also evaluated whether the anesthetic method was associated with the parturients’ length of hospital stay.Results: General anesthesia, spinal anesthesia, and epidural anesthesia were induced in 28.8%, 47.7%, and 23.6% of parturients from 2013 to 2018, respectively. Trend analyses showed that spinal anesthesia increased from 40.0% in 2013 to 53.7% in 2018. The opposite trend applied to general anesthesia, decreasing from 37.1% in 2013 to 22.2% in 2018. The factors that were significantly associated with the anesthetic method were parturient’s parity, emergency condition, gestational age, and fetal weight. The type of hospital, parturient’s age, and multiple birth were also associated with the anesthetic methods. There was a strong association between general anesthesia and hospital stay longer than 7 days.Conclusions: Spinal anesthesia is currently the main anesthetic method used for cesarean delivery, and the rate of spinal anesthesia is gradually increasing in Korea.

Objective: As the population of patients aged 65 years and older increases, the number of older adult patients undergoing surgery also increases. Older adults are vulnerable to hypothermia due to age-related changes in the thermoregulatory center, which leads to reduced subcutaneous fat tissue, vasomotor response, and heat production. Thus, they are more likely to suffer complications, including cardiovascular changes, blood coagulation disorders, infections, and delayed recovery from surgery. The study investigated the effect of preventive active warming. Methods: This retrospective cohort study conducted at Chungbuk National University Hospital investigated clinical data from older adult patients undergoing spinal surgery from January 1, 2020, to December 13, 2022. In this study, we explored the use of prophylactic active warming during anesthesia induction and post-surgery warming in older adult patients (≥65 years) who experienced hypothermia during and after surgery under general anesthesia. Results: The control group of patients who experienced hypothermia increased from 20% after 10 minutes to 80% after 30 minutes and 100% after 60 minutes. The percentage of patients in the treatment group who initially experienced hypothermia increased from 10% after 30 min to 40% after 60 minutes. However, notably, 90% of these patients had returned to a normal body temperature upon their arrival at the recovery room. The difference in the percentage of patients who developed hypothermia was statistically significant between the two groups. Conclusions: Hypothermia prevention via an air-forced warming blanket was effective for older adult patients undergoing spinal surgery under general anesthesia. doi: https://doi.org/10.12669/pjms.40.4.7886 How to cite this: Shin Y, Lee J, Seo H, Park S.
