ObjectiveTo investigate the effcacy of subcutaneous placement of negative pressure drainage tube in the prevention of incision fat liquefaction in obese patients after abdominal surgery. MethodsThe wound healing situation in 84 obese patients who underwent abdominal surgery in our department from January 2013 to May 2015 were retrospectively analyzed. The patients were divided into tube placement group (n=39) and control group (n=45). Patients in the tube placement group accepted negative pressure drainage tube placement, while those in the control group underwent routine suturing of the incision without negative pressure drainage tube. The incision healing grade and fat liquefaction rate of the two groups of patients were compared and analyzed. ResultsThere was no significant diTherence in grade-A and –B healing rate and fat liquefaction rate between the two groups (P>0.05), but grade-C healing rate and the second-stage suturing rate in the tube placement group were significantly lower than those of the control group (P<0.05). There was no significant diTherence in grade-C healing rate between the two groups for type-Ⅱ incisions (P>0.05), while the grade-C healing rat of patients with type-Ⅲ incisions was significantly lower in the tube placement group than that in the control group (P<0.05). ConclusionNegative pressure drainage tube can decrease grade-C healing rate and second-stage suturing rate as well as grade-C healing rate of type-Ⅲ incisions in obese patients after abdominal surgery.
ObjectiveTo evaluate the effect of fast track surgery (FTS) on clinical parameters and postoperative complications in patients with abdominal aortic aneurysm (AAA). MethodFifty Patients with AAA treated in our hospital between December 2009 and May 2015 were enrolled in this study. Ten patients between December 2009 and December 2012 received conventional standard care (conventional group), while 50 between January 2013 and May 2015 received FTS (FTS group). The first exhaust time, the first time of off-bed activities, the duration of hospital stays, and the complications after AAA surgery were analyzed. ResultsThe first exhaust time of patients in the FTS group and conventional group was (2.5±0.9) and (4.0±1.1) days; the first time of off-bed activities was (2.9±1.0) and (4.1±0.9) days; and the duration of hospital stays was (13.5±2.1) and (17.9±2.8) days. All those differences were significant (P<0.05). The incidences of incision infection, renal inadequacy, lower limb swelling, and weakened gastric function in the FTS group were significantly lower than those in the conventional group (P<0.05). On the third day after surgery, C-reactive protein in the FTS and conventional group was respectively (57.5±9.0) and (65.0±13.1) mg/L, and interleukin-6 was respectively (10.2±3.9) and (15.5±5.1) pg/L, both of which were significantly different between the two groups (P<0.05). ConclusionsFast track surgery is effective and safe in patients with abdominal aortic aneurysm, and it may lower trauma stress after surgery and incidence of postoperative complications.
