Objective:To evaluate the development of hypothermia after spinal anesthesia and risk factors.Methods:Patients undergoing spinal anesthesia in the anesthesia preparation room of our hospital from April 2020 to April 2021 were included. The temperature of the tympanic membrane was measured before spinal anesthesia and immediately after anesthesia and at 5, 10 and 15 min after anesthesia. Patients with tympanic membrane temperature<36 ℃ at any time point were considered as having hypothermia and included in hypothermia group and patients with membrane temperature ≥ 36 ℃ were considered as having no hypothermia and included in non-hypothermia group. The patients′ demographic data, highest anesthesia plane, puncture space of spinal anesthesia, types of anesthetics, preoperative fasting time, and surgical sites were recorded. The multivariate logistic regression analysis was performed to identify the risk factors for hypothermia.Results:A total of 196 patients were finally enrolled. The body temperature was significantly decreased at 5 and 10 min after anesthesia compared with the baseline body temperature before anesthesia and immediately after anesthesia ( P<0.001), and the incidence of hypothermia was 10.2%. The multivariate logistic regression analysis showed that female and high anesthesia plane were independent risk factors for hypothermia, and higher baseline body temperature was an independent protective factor for hypothermia ( P<0.05). Conclusions:Body temperature decreases at 5-10 min after spinal anesthesia, and the occurrence of hypothermia is not a small probability event in the patients undergoing spinal anesthesia; female and higher anesthesia plane are risk factors and higher baseline body temperature is the protective factor.

Objective:To investigate and analyze the awareness of malignant hyperthermia (MH) in anesthesiology nurses in mainland China.Methods:From November 2021 to January 2022, anesthesiology nurses of secondary hospitals or above in Chinese mainland were enrolled by convenience sampling and investigated by a self-designed questionnaire on the awareness of MH.The system automatically recorded the situation of questionnaires.Results:A total of 2 058 anesthesiology nurses participated in the survey, distributed in 21 provinces, 2 autonomous regions (Ningxia Hui Autonomous Region, Guangxi Zhuang Autonomous Region) and 4 municipalities directly under the central government, and 2 049 questionnaires were effectively received with effective recovery of 99.56%.The correct answers to questions related to the treatment of MH, characteristics of the disease, classification, susceptible population, screening method of the susceptible population, genetic mode, inducing factors, the first symptoms and the best infusion time of dantrolene, preparation method of domestic dantrolene and the first dose were 86.58%, 82.33%, 58.18%, 50.90%, 50.76%, 50.42%, 45.73%, 32.89%, 51.25%, 48.32% and 46.51%, respectively.Only 27.13% of anesthesiology nurses expressed that dantrolene was available in their hospital.The scores of knowledge about MH among anesthesiology nurses in hospitals of province-level municipalities and provincial capital cities were significantly higher than those in other cities ( P<0.001). The scores of knowledge about MH among the anesthesiology nurses in secondary hospitals were significantly higher than those in tertiary hospitals ( P<0.05). There was no significant difference in the scores of knowledge about MH among anesthesiology nurses with different professional titles, educational backgrounds, and working years ( P>0.05). Conclusions:Anesthesiology nurses in mainland China have insufficient awareness of MH.Popularizing the knowledge about MH and strengthening the awareness of MH in medical staff in the department of anesthesiology throughout the country may be of great significance in improving the diagnosis and treatment of MH in China.

Objective:To investigate the current situation of core competence of anesthesiology nurses in China, and to provide basis for formulating and perfecting the training curriculum of anesthesiology nurses.Methods:The cluster sampling method was used, and 231 nurses in the department of anesthesiology were investigated by using the general data questionnaire and the self-assessment form of core competence of specialized nurses in the department of anesthesiology.Results:Anesthesiology nurses scored (3.7±0.5) points in their core competencies, of which 43.2% and 36.4% had complete mastery of humanistic literacy, and communication and coordination skills, respectively, and only 4.3% of them had mastered scientific research ability.The core competence scores of anesthesiology nurses with the title of head nurse or above positions and deputy chief nurse or above titles were significantly higher than those of other positions and titles ( P<0.05). Conclusions:The self-evaluation of core competence of specialized nurses in anesthesiology department is at a medium level.There are differences in core competencies among nurses in the department of anesthesiology with different positions and titles.It is suggested that the training of specialized nurses should be guided by core competence.
