RESUMEN
Objective:To investigate the training status of robotic-assisted surgery nurses in hospitals with robotic-assisted surgery system in China, and to provide reference for the training and management of robotic-assisted surgery nurses.Methods:From August to December in 2021, hospitals with robotic-assisted surgery system in China were surveyed by a self-designed questionnaire distributed online.Results:The participants in the survey of 111 hospitals in 30 provinces, cities, autonomous regions and municipalities directly under the central government, nurses cooperated with robotic-assisted surgery exist the phenomenon of their own training was up to 96.40% (107/111) of hospital, 47.75% (53/111) of the hospital said the current training content also need to add other aspects of the course. Training duration of theoretical courses was 0-13 (2.86 ± 3.03) periods arranged by hospitals, and the training duration of practical courses was 1-60 (8.38 ± 9.91) d. 35.14% (39/111) of hospitals set up regular assessment after training, and the assessment cycle of them was 1-12 (4.08 ± 3.31) months. Many hospitals put forward suggestions on strengthening English training and attaching importance to team cooperation and so on.Conclusions:In our country, Robotic-assisted surgery nurses′ training has turned to that training themselves in operating rooms, the training time, form, content and other aspects have no uniform standard, strict admittance, standardization of specialist training , these are questions need to solve.
RESUMEN
Objective To explore the effects of modified herringbone-Trendelenburg position during gynecological laparoscopic operation of the elderly. Methods A total of 60 elderly patients undergoing gynecological laparoscopic operation under general anesthesia were recruited and assigned to the observation group (30 cases) and control group (30 cases) by random digits table method with 30 cases each according to admitting time;Patients in the control group were placed in conventional Trendelenburg position, while the patients in the observation group were positioned in modified herringbone-Trendelenburg position .Intraocular pressure (IOP) were measured in the patients at anesthesia induction (T1),5 minutes after general anesthesia in supine position (T2) , and 5 minutes after pneumoperitoneum while in the operation position (T3) , every 30 minutes (times 4 to 11), while supine at the end of pneumoperitoneum (time 12) and before awakening (time 13);Patients were followed up at 24 h and 48 h after surgery, researcher investigate and record the scores of the Operation Position Comfort Questionnaire, the situation of the pain in the shoulder and postoperative complications of the lower limbs. Results There was no statistically significant difference (t=-1.098,-0.772,-0.656, P>0.05) of the IOP at T1, T2, T13. The IOP in the observation group had statistically significant difference compared with the control group at T3 to T12 (t=6.523-19.866, P<0.01). The incidence rate of the postoperative complications of the lower limbs in the observation group was 6.7%(2/30) lower than 26.7%(8/30) of the control group (χ2=4.320, P<0.05) and the VAS scores of the patients in the two groups was statistically significant (t=2.471, P<0.05). The incidence rate of the postoperative shoulder pain in the observation group was 10.0%(3/30) lower than 43.3%(13/30) of the control group (χ2=8.523, P<0.01), and the Visual Analogue Scale scores of the patients in the two groups was statistically significant (t=3.575, P<0.05).The scores of the Operation Position Comfort Questionnaire in the observation group was higher than the control group (t=-2.319, P<0.05). Conclusions Modified herringbone- Trendelenburg position can reduce the elevation of intraocular pressure in elderly patients without affecting the operation ,and effectively improve the comfort of the operation position of the patients, reduce the incidence rate of the shoulder pain and postoperative complications of the lower limbs, is conducive to the operation safety of elderly patients.

Objective To explore the effect of different temperature of the forced- air warming system on the prevention of hypothermia during laparotomy of infants. Methods A total of 60 infants undergoing laparotomy under general anesthesia were recruited and divided into three groups by random digits table method with 20 cases each according to admitting time; when used the force- air warming system intraoperatively, the three groups were respectively setting on 45℃(automatic adjustment for 43 ℃ after 45 minutes), 43 ℃ and 38 ℃.The core temperature were respectively recorded before anesthesia and 15, 30, 45, 60 minutes after anesthesia (every 30 minutes after 1 hour).The hypothermia incidence and anesthesia recovery conditions were recorded simultaneously. Results There was no significant difference on the core temperature among three groups before anesthesia (P > 0.05). 30 minutes after the anesthetic, the core temperature of 45 ℃ group was (36.31±0.20) ℃,43 ℃ group was (36.32±0.24) ℃ and 38 ℃ group was (36.08±0.21) ℃.The differences among three groups was statistically significant (F=8.12, P 0.05). 60 minutes after the anesthetic, the core temperature of 45 ℃ group was (36.39±0.26) ℃,43 ℃ group was (36.19±0.22) ℃ and 38 ℃ group was (35.92±0.15) ℃. The differences among three groups was statistically significant(F=25.19, P<0.01).The hypothermia incidence of 45℃group, 43℃ group,38℃ group was 10.0%(2/20), 25.0%(5/20), 50.0%(10/20)respectively and the differences among three groups was statistically significant( χ2=8.04, P<0.05). The time to complete consciousness of 45 ℃ group was (15.40±5.09) minutes,43 ℃ group was (19.80±4.10) minutes and 38 ℃ group was (22.00±4.36) minutes. The differences among three groups was statistically significant (F=10.96, P<0.01). The time to tracheal extubation of 45 ℃ group was (18.10±5.97) minutes, 43 ℃ group was (21.85±4.02) minutes and 38 ℃ group was (24.90±5.54) minutes.The differences among three groups was statistically significant (F=9.83, P<0.01). Conclusions The forced-air warming system can increase the infants′peripheral tissue heat content and reduce the heat losing.So that it will help decrease the intraoperative hypothermia incidence and shorten the anesthesia recovery period.Meanwhile the higher temperature of the forced-air warming system is setted ,the better effect it is.

RESUMEN
Effects on surface microstructure and mechanical property of pure titanium (TA1) for implant treated by anodic oxidation were investigated. We found that the oxide film with a certain uniform and compact color could be achieved by anodic oxidation method. However, with the increasing of oxidizing voltage and time, the oxide film will be dissolved at local area. The oxygen content of oxide film and the hydrogen content of matrix titanium will be raised, and will also be increased. In fact, hydrogen could be diffused into matrix titanium. With the increase of hydrogen content of matrix titanium and sigmas/sigmab, there appear the possible results of plastic deformation and the fracture of implant.
