RESUMEN
Objective:To investigate the clinical effects of perforator flaps in the repair of limb defects.Methods:Anterolateral thigh perforator flap (ALTP), deep inferior epigastric perforator flap (DIEP), posterior in- terosseous artery perforator flap (PIAP), thoracodorsal artery perforator flap (TDAP), medial sural artery perforator flap (MSAP) and radial collateral artery perforator flap (RCAP) were used to repair 56 cases of limb wounds from Novem- ber, 2016 to October, 2018. The sizes of soft tissue defect were ranged from 1.5 cm×1.5 cm to 10.0 cm×24.0 cm, while the sizes of flap were ranged from 2.0 cm×2.0 cm to 11.0 cm×25.0 cm. The recipient sites were all sutured di- rectly. The flaps survived and wound healing were observed postoperatively. Appearance, texture, recovery of the limb function, shape and function of donor site were followed-up regularly.Results:One case of venous crisis occurred on the 3rd day after inferior epigastric artery perforator flap surgery, and survived after exploratory surgery with the necrosis in the distal part of the flap, which healed after dressing. Other 55 flaps all survived. Both recipient site and donor site healed in primary union. The color of the flaps was normal. The skins were soft, and the functions of the limbs recovered well. Only a linear scar remained in the donor area without dysfunction.Conclusion:The perforator flap surgery is reliable for limbs repair and can be promoted and applied.
RESUMEN
Objective To study the effect of propofol used for outpatient painless enteroscope on cognitive function.Methods One hundred and twenty ASAⅠ~Ⅱpatients scheduled for enteroscope were randomly divided into three groups .Propofol was given 1.5mg/kg(groupⅠ), 2mg /kg (group Ⅱ) or 2.5 mg/kg ( group Ⅲ) intravenously .The enteroscope was inserted when patient showed unconsciousness and no reaction to dictation .SpO2 was kept above 95%96% throughout enteroscope .All patients received neurobehavioral cognitive status examination ( NCSE ) and mini-mental state examination ( MMSE ) test 1 hour before enteroscope examination and 5 minutes,30 minutes, 1 hour after enteroscope examination was o-ver and must finish it within 15 min.The enteroscope examination time , vital signs, analgesia effects and intraoperative awareness were record .Results The ability of memory and calculation at 5 minutes after en-teroscope examination showed a statistical difference between group Ⅰ and ⅡorⅢ( P 0.05 ) , The ability of memory and calcu-lation at 30 minutes, 1 hour after enteroscope examination there was no significant difference in three groups ( P >0.05 ) .In all patients ,the MMSE scores at 5 minutes after enteroscope examination were significant-ly lower than the baseline value ( P 0.05 ) .The NCSE and MMSE scores at 3hour, 12 hour after enteroscope examination there was no significant difference between in group I and II or Ⅲ( P >0.05).Conclusion Propofol 1.5mg/kg used for painless enteroscope examination has no effect on cognitive function .MMSE and NCSE are suitable for evaluation of outpatient's cognitive func-tion.
