To meet the requirements of modern field first-aid operation, a field operating table, which can be wholly folded, is developed in this paper. The table consists of a bracket and a board. The trigonal bracket, with double arms, has an articulated shoring. The posture regulation part is composed of the wormwheel, worm, rocker of plate and shoring fittings of all segments of the table. According to the measurements of its dimensions and posture angle, military experiment, experiments for stability, load, regulation moment and simulate transportation on the third level of road, S2001 field operating table is suitable for the operations on head and cervix, chest and abdomen, limbs, urinary organs and the five sense organs, whose wholly-fold structure contributes to rapid deployment and undeployment in the field.

OBJECTIVE: To investigate the level of formaldehyde in the air of anatomical laboratories and to explore the effect of different prevention measures on reducing the level of formaldehyde. METHODS: The level of formaldehyde in two morphological laboratories of a medical college of a university were measured with a comprehensive atmospheric sampler at different physical ventilation time,different time after spraying biological enzymes and different masks. RESULTS: The level of formaldehyde decreased with the increase of ventilation time in front,middle and back of the laboratory( P < 0. 05).The level of formaldehyde at 30 and 60 minutes after spraying bio-enzymes in three parts of the laboratory was lower than that at 0 minute in the same part of the laboratory( P < 0. 05),and lower than that in the bio-enzymes non-spraying laboratory at the same part and same time point( P < 0. 05). At 0,30 and 60 minutes ventilation time points,the level of formaldehyde in the activated carbon mask group was lower than that in the normal sampling group,the non-woven mask group and the defatted gauze mask group at the same time point( P < 0. 05). CONCLUSION: Both physical ventilation and bio-enzyme degradation can reduce indoor formaldehyde pollution. Active carbon mask can achieve good protection effect.

Objective To explore the effect of different hyperbaric oxygen treatment (HBOT) on delayed neuropsychiatric sequelae followed carbon monoxide (CO) poisoning (DNS).Methods Patients diagnosed acute carbon monoxide poisoning (ACOP) or DNS due to CO poisoning in the hospital from October 2015 to October 2016 were included.Patients who died of ACOP or in persisting unconsciousness condition were excluded.Information of the patients were retrospectively collected including personal data,clinical features and treatment course of hyperbaric oxygen (HBO).All subjects were divided into two groups,consisting of cases who developed into DNS and who fully recovered,according toclinical symptoms.The differences of personal data,clinical features and treatment course of HBO were compared between the two groups.After adjusting the confounding factors,hyperbaric oxygen treatment program of the two groups were analyzed.Results DNS occurred in 39 patients with acute CO poisoning,while 130 patients were fully recovery.The ratio of patients over 55 years old or with smoking history in the DNS group were higher than that in the good outcome group (82.1% vs.60.8%,23.1% vs.10.8%).Patients who awoke from unconsciousness but left cognitive impairment were more likely to develop into DNS (P=0.017).Patients who treated with HBO within the first 24 hours,risk of developing into DNS were decreased(OR=0.14,P<0.01).At the same time,2 times per day and within the first 24 hours worked also as well.(OR=0.29,P=0.011).Even if patients who were given 2 times a day of HBO but not in the first 24 hours after poisoning,could not reduce the risk of evolving to DNS(OR=0.06,P>0.05);The proportion of patients in the good outcome group accepted HBO for more than six days after poisoning was higher than that in the DNS group (68.5% vs.48.7%).After adjusting confounding factors,patients who treated with HBO within the first 24 hours (OR=0.22,95%CI:0.09-0.52),2 times per day(OR=0.30,95%CI:0.10-0.87)and lasted for more than 6 days(OR=0.30,95%CI:0.10-0.87)were in a lower risk of involving to DNS.Conclusions For patients diagnosed ACOP,HBOT began in the first 24 hours,1 or 2 times per day or early sustaining to give HBO for more than 6 days could reduce the risk of DNS.

Objective:To study the changes of stenotic segment trachea diameter, trachea length and carina angle before and after slide tracheoplasty.Methods:From January 2010 to January 2018, 77 children with congenital tracheal stenosis(female=36) with complete clinical data accepted slide tracheoplasty in Shanghai Children's Medical Center were selected as the observation group. The diameter of stenosis segment, the length of stenosis segment, the full length of trachea and carina angle were measured by CT image, and the ratio of stenosis segment length to full trachea length was calculated. A group of children with normal trachea morphology and the same sample number, and they had no significant difference in age, height and weight were selected as the control group.Results:The median operative age of 77 children in the observation group was 1.3(1.1, 1.9)years old, the height was 76.0(72.0, 83.0)cm, and the weight was 9.0(7.9, 10.8)kg. The age, height and weight of 77 children in the control group were 1.5(1.0, 2.0) years old and 78.0(71.0, 85.0) cm, 9.2(7.9, 11.0) kg respectively. After slide tracheoplasty, the diameter of trachea in the stenotic segment of children increased from 2.7 mm to 4.4 mm, which was increased by 63.0%( P<0.001), but still smaller than that of children in the control group(6.1 mm). The average length of trachea was shortened by 0.7 cm( P<0.001), and there was no significant difference between the total length of trachea(5.4 cm) and the total length of trachea(5.5 cm). The postoperative carina angle decreased by 27.9°( P<0.001), there was no significant difference in postoperative carina angle between the observation group(93.0°) and the control group(90.7°). Conclusion:The diameter of reconstructed trachea in children with CTS is significantly increased, the length and carina angle of trachea become smaller after slide tracheoplasty. The morphology of trachea is more similar to children in the control group.
