Objective To investigate the effect of perioperative body temperature on the survival of skin flap grafting. Methods From July 2005 to November 2006, 50 cases of Ⅰ-Ⅱ grade patients undergoing elective skin flap grafting were randomly divided 2 groups. Pharyngeal temperature (PT) and skin temperature(ST) were monitored and recorded every 15 minutes. Operativetime, anesthetic time, time from the end of operation to extubation, the volume of blood transfusion, the volume of fluid transfusion and the flap survival 7 days after operation were recorded. In the experimental group, the body temperature was maintained in normal range with water market and forced air heater. In the control group， the body temperature was only monitored without any treatment. Results There were no significant differences in operating room temperature, operative time, anesthetic time, the volume of blood transfusion and fluid transfusion between 2 groups(Pgt;0.05). After induction, PT decreased gradually inboth groups during the first 45 minutes, compared with the time point of intubation(Plt;0.05),but there were no significant differences between the 2 groups(Pgt;0.05); and ST rose in both groups during the first45 minutes, compared with the time point of intubation (Plt;0.05). After 45 minutes of induction, in the experimental group, PT was in the normal range(36℃), and ST didn’t change compared with that of the timepoint of induction(Pgt;0.05). In the control group, both PT and ST decreasedgradually and timedependently compared with the time point of intubation (Plt;0.05). In the experimental group, PT and ST at each time point were higher than those in the control group (Plt;0.05). All the skin flap grafts survived in the experimental group, and skin flap grafts necrosed in 2 cases in the control group.Conclusion Keeping normal body temperature can improve the survival ofskin flap grafting. Therefore, the body temperature should be monitored and maintained in a normal range.
Objective To systematically review the efficacy of maternal body temperature preservation during caesarean section. Methods Databases including PubMed, EMbase, The Cochrane Library (Issue 2, 2015), WanFang Data, CBM and CNKI were searched from inception to July 2015 to collect randomized controlled trials (RCTs) of body temperature preservation in patients with caesarean delivery. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Then, meta-analysis was performed using RevMan5.3 software. Results A total of 15 RCTs involving 1 331 patients were included. The results of meta-analysis showed that patients in the temperature preservation group had a smaller body temperature variation (MD= –0.22, 95%CI –0.32 to –0.13, P < 0.000 01) and a lower incidence of shivering (RR=0.53, 95%CI 0.42 to 0.67, P < 0.000 01) than patients in the control group. There were no statistical differences between the two groups in blood loss (MD= –13.77, 95%CI –33.95 to 6.42, P=0.18) and newborn Apgar score (MD=0.12, 95%CI –0.37 to 0.6, P=0.64). Conclusions Current evidence shows that body temperature preservation measures can better protect patients with caesarean delivery. Specifically, body temperature preservation measures could reduce patients’ body temperature variation and incidence of shivering but had no effect on blood loss and newborn Apgar score. Due to limited quality and quantity of the included studies, more high quality studies are needed to verify the above conclusion.
ObjectiveTo study the method of rapid and accurate measurement of body temperature in dense population during the coronavirus disease 2019 pandemic.MethodsFrom January 27th to February 8th, 2020, subjects were respectively measured with two kinds of non-contact infrared thermometers (blue thermometer and red one) to measure the temperature of forehead, neck, and inner side of forearm under the conditions of 4–6℃ (n=152), 7–10℃ (n=103), and 11–25℃ (n=209), while the temperature of axillary was measured with mercury thermometer under the same conditions. Taking the mercury thermometer temperature as the gold standard, the measurement results with non-contact infrared thermometers were compared.ResultsAt 7–10℃, there was no statistical difference among the forehead temperatures measured by the two non-contact infrared thermometers and the axillary temperature (P>0.05); there was no difference among the temperature measured by blue thermometer on forehead, neck, and inner side of forearm (P>0.05); no difference was found between the temperature measured by the red thermometer on forehead and inner side of forearm (P>0.05), while there was statistical difference between the temperatures measured by the red thermometer on forehead and neck (P<0.05). Under the environment of 11−25℃, there was no statistical difference among the forehead temperatures measured by the two infrared thermometers and the axillary temperature (P>0.05); the difference between the temperatures of forehead and inner side of forearm measured by the blue thermometer was statistically significant (P<0.05), while no difference appeared between the forehead and neck temperatures measured by the blue thermometer (P>0.05); there was no statistical difference among the temperatures of three body regions mentioned above measured by the red thermometer (P>0.05). According to the manual, the allowable fluctuation range of the blue thermometer was 0.3℃, and that of the red one was 0.2℃. The mean differences in measured values between different measured sites of the two products were within the allowable fluctuation range. Therefore, the differences had no clinical significance in the environment of 7–25℃. Under the environment of 4–6℃, the detection rate of blue thermometer was 2.2% and that of the red one was 19.1%.ConclusionsThere is no clinical difference between the temperature measured by mercury thermometer and the temperature measured by temperature guns at 7–10 or 11–25℃, so temperature guns can be widely used. In order to maintain the maximum distance between the measuring and the measured persons and reduce the infection risk, it is recommended to choose the inner forearm for temperature measurement. Under the environment of ambient temperature 4–6℃, the detection rate of non-contact electronic temperature gun is low, requiring taking thermal measures for the instrument.
