Objective To observe the influence of two feeding ways m coma patients at gastrointestinal tract complications.Methods Seventy patients were assigned randomly to two groups according to different feeding ways:entogastric continuing infusion (observation group,n=35) and entogastric manualinfusion (control group,n=35) from June 2006 to May 2007,and observed the ratio of gastrointestinal tract complications in two groups.Results Different feeding ways had significantly correlated with the complications of gastrointestinal tract.The ratio of gastrointestinal tract complications in observation group was lower (20.00%)than that in control group (42.86%).There was statistically significant difference in two groups,P＜0.05.Conclusion The ratio of gastrointestinal tract complications could obvious reduce in entogastric nutrition continuing infusion in coma patients.

Objective The aim of the study was to evaluate the hearing performance of a new transcutaneous bone conduction hearing aid.Methods One hundred and nine patients with conductive or mix hearing loss and eleven patients with single sided sensorineural hearing loss from four tertiary referral centers were tested under unaided and aided conditions with the sound processors on testbands.Free field test was performed to obtain the hearing thresholds and speech recognition thresholds in quiet.Adverse events were also documented by a self-reported questionnaire.Results ①Conductive or mixed hearing loss patients:for aged≥6 yrs subgroup,the bone conduction PTA average of aided sides was 18.55±8.99 dB HL.For aged<6 yrs subgroup, the bone conduction ABR hearing threshold average was 18.33±8.36 dB HL.②Statistically significant improvements in free field hearing thresholds were seen when compared aided hearing with unaided outcomes.The average PTA (pure tone average in free field) was measured at 32.21±10.00, 37.33±14.15, and 34.38±10.76 dB HL respectively in conductive or mixed hearing loss aged≥6 yrs subgroup;aged<6 yrs subgroup and SSD subgroup.③In aided situations;speech recognition thresholds in quiet were significantly better compared to unaided situation in patients aged≥6yrs.④None of patients presented adverse events related to the devices.Conclusion The Sophono bone conduction hearing aid has satisfactory hearing performance and can be considered an alternative device for patients with conductive or mix hearing loss or with SSD.
