Objective To develop and perfect the infusion function of field operation stretcher by attaching infusion support.Methods The linking structure was developed for conveniently mounting infusion support to field operation stretcher so as to pack them off together.Results The infusion support is simple to operate,reasonable in structure,convenient to put off,and suitable for various field operation stretcher.Conclusion The field rescue,especially the quality of casualty transports,is improved.The manpower and material resources needed in on-site rescue are greatly reduced.[Chinese Medical Equipment Journal,2008,29(2):68]

Objective To investigate the curative effect of low-temperature plasma-assisted uvulopalatopharyngoplasty(UP-PP)in the patients with positional and non-positional obstructive sleep apnea-hypopnea syndrome(OSAHS).Methods Twenty-six patients with OSAHS diagnosed by polysomnography monitoring receiving the low-temperature plasma-assisted UPPP in our hospital from January 2014 to December 2015 were selected and divided into the positional OSAHS group(PPs) and non-positional OSAHS group(NPPs) according to the apnea-hypopnea index (AHI) under different sleep positional status.The AHI change before and after operation and operation effective rate were compared between the two groups.Results Theoverall AHI,supine position AHI and lateral position AHI in the PPs group all were lower than those in the NPPs group(P＜0.05),moreover the blood oxygen related indexes were higher than those in the NPPs group(P＜0.05).The overall surgical effective rate in the OSAHS patients was 73.08％ (19/26),in which the surgical effective rate was 100％ (7/7) in the PPs group and 63.16％ (12/19) in the NPPs group,the difference between the two groups had no statistical significance(P=0.13).The postoperative total AHI,supine position AHI and lateral position AHI in the two groups were decreased compared with before operation(P＜0.05);the decrease range of lateral position AHI in the NPPs group was significantly higher than that in the supine position AHI[0.96(0.86,1.00)vs.0.53(0.34,0.77),P＜0.01].78.95 ％ (15/19) postoperation patients in the NPPs group converted to PPs.Conclusion Low-temperature plasma-assisted UPPP has some effects on OSAHS patients,in which the benefit of NPPs are more apparent.
