Objective:To explore the clinical application of ultrasound-guided anterior serratus plane block (SAPB) in anesthesia and postoperative analgesia of thoracoscopic surgery and to provide theoretical basis for clinical practice.Methods:From June 2018 to June 2019, a total of 90 patients with thoracoscopic surgery in Nanhai District People's Hospital of Foshan were randomly divided into three groups, 30 cases in each group. Group A received routine general anesthesia; Group B received preoperative SAPB+ routine general anesthesia; Group C was treated preoperatively SAPB+ single dose of 1 μg/kg dexmedetomidine+ routine general anesthesia. The mean arterial pressure (MAP) and heart rate (HR) of the three groups were compared after entering the room, immediately after intubation, during skin incision and immediately after extubation. The intraoperative dosage of propofol and remifentanil, the effective pressing times of analgesic pump within 48 hours, the dosage of sufentanil, the level of analgesia, adverse reactions and satisfaction were compared.Results:There was no significant difference in MAP and HR of the three groups of patients when they entering the room ( P>0.05); the MAP and HR of the three groups at the time of intubation, skin incision and extubation were higher than those at the time of entry ( P<0.05); the MAP and HR of B group and C group were lower than group A at the time of intubation, skin incision and extubation (all P<0.05). There was no significant difference in the intraoperative doses of remifentanil and propofol among the three groups (all P>0.05). The effective pressing times of analgesic pump and the dosage of sufentanil in group B and group C within 48 hours were lower than those in group A (all P<0.05). The pain scores in resting state and cough state at 2, 4, 12 and 24 hours after operation in group C were lower than those in group B and group A (all P<0.05). The incidence of postoperative adverse reactions in group B and group C was lower than that in group A (all P<0.05). The postoperative satisfaction of group B and group C was higher than that of group A (all P<0.05). Conclusions:SAPB guided by ultrasound combined with general anesthesia and single dose of dexmedetomidine can effectively improve hemodynamic indexes, relieve pain, and have high safety and satisfation in patients undergoing thoracoscopic surgery. The treatment effect is significant and can be widely used in clinical practice.

Effects of exposure to power frequency electromagnetic fields on humoral immune function in transformer substation workers / 中国职业医学

OBJECTIVE: To explore the effects of long-term exposure to power frequency electromagnetic fields on the humoral immune function in transformer substation workers. METHODS: By simple random sampling method,64 workers with length of service longer than 5. 0 years in 500 k V transformer substation were chosen as exposure group and 57 general administrative staffs without exposure to power frequency electromagnetic field were chosen as control group. Venous blood was collected from subjects of these two groups and the levels of immunoglobulin( Ig) A,Ig G,Ig M,complement( C) 3and C4 in plasma were examined by immunoturbidimetry. RESULTS: Compared with the control group,the levels of both Ig A and Ig G increased( P < 0. 05),while both levels of C3 and C4 decreased( P < 0. 05) in exposure group. Compared with the control,the level of Ig G increased( P < 0. 05),while the levels of both C3 and C4 decreased( P < 0. 05) in exposure subgroup with length of service ≤10. 0 years. The level of C4 decreased( P < 0. 05) in exposure subgroup with length of service > 10. 0 years. CONCLUSION: Long-term exposure to power frequency electromagnetic fields may activate the humoral immune function in transformer substation workers.

It was reported that Puerarin injection can not only induce adverse reactions on multiple systems, such as immune, blood, urinary, digestive and cardiovascular system, but so far as to cause death. Therefore, it should be administered rationally and strictly according to the direction and the course of medication should be rigorously monitored to prevent the occurrence of adverse reactions.

Risk Factors and Intervention in ICU Nosocomial Infection / 中华医院感染学杂志

OBJECTIVE To explore the characteristics and intervention measures of nosocomial infection in ICU.METHODS Retrospective investigation was used to analyze the nosocomial infection cases in 145 patients discharged from ICU.RESULTS Of 145 inpatients,35 developed nosocomial infection with an infection rate of 24.14%.Elderly patients with severe diseases were the high risk group.The causes of infection were related to the increase of traumatic operation,hypoimmumity and unreasonable antibiotics usage.Lacking awareness of cross infection in medical and nursing staff was another factor facilitating the occurrence of infection.CONCLUSIONS Nosocomial infection rate in patients in ICU is high.Close attention should be paid to the old patients.Nursing intervention of respiratory tract,gastrointestinal tract and urinary tract should be given to the patients with severe diseases.The illegal use of antibiotics and traumatic operation should be limited.

INVESTIGATION ON THE NUTRITIONAL STATUS AND PHYSICAL DEVELOPMENT OF THE 0～6 YEARS OLD CHILDREN OF DIFFER ENT NATIONALITIES / 营养学报

Objective: To investigate the childrens congenital and acquired nutritional status and the physical development among the different nationalities in Guizhou province; to find out the factors that greatly influence the childrens physical development. Methods: Investigations were carried out on the diet, height and the weight of the mothers during the early and late stage of their pregnancy and after the delivery of the babies. Results: The living conditions in the groups of Miao and Buyi were very poor. For the pregnant women among Han, Miao and Buyi groups, during their middle and late stage of the pregnancy, the intakes of protein, calcium and VB 2 did not reach 80% RDA. For the 2-4 years old children, the intake of protein was below 80% RDA. For those in Miao and Buyi groups, the chief source of protein was from cereals. There was a great insufficient intake of calcium and VB 2 in different age groups of the children mentioned above. With the increase of age, the infants of Buyi and Miao groups were gradually diverting from the standard criterion from 3rd or 4th month. The greatest difference was in Miao group, i.e. at the age of 6, the difference in height was 9.8 cm(male), 8.3 cm(female); the difference in weight was 1.64 kg(male), 1.92 kg(female). Conclusion: The physical development of the infants in Buyi and Miao groups is inferior to those in Han group. Besides the environmental influence, the quality and quantity of the protein in diet play an important role in physical development.
