Abstract
Objective: to study the influence of restrictive fluid therapy combined withpreoperative urination training during perioperative period in an enhanced recovery after surgery (ERAS) program for total knee arthroplasty (TKA).
Methods: 150 patients who received the unilateral TKA from March 2018 to May 2018 were divided into two groups,the trial groupand the controlgroup.75 patients withliberal intravenous fluid therapy on the day of surgery and had no preoperative urination training were the controlgroup, and the other 75 patients with restrictive fluid therapy and preoperative urination trainingwere the trial group.There was no significant difference in gender, age, body mass index between the two groups (P>0.05).Perioperative related indexes were recorded and comparedbetween the two groups, including pre-, intra-, post-operative intravenous fluid volumes, urinationsituation and urinationtime for the first time,hospital days.
Results:The total infusion volume of patients in the trial group was around 1500 ml on the day of operation（1581.40±277.54ml）,the control group was around 2400ml（2395.00±257.40 ml. Urination situation for the first time had significant difference in the two groups, in the trial group,urinate smoothly patients were 73 , urinate smoothly after inducing method patients were 2 , urethral catheterization 0 ; in the control group,urinate smoothly patients were 66, urinate smoothly after inducing method patients were3, urethral catheterizationpatients were6.Theurinationtime for the first time after operation and the hospital staysin trial groupwere lower than those in control group (P<0.05).Conclusion:Based on the concept of ERAS, restrictive fluid therapy and preoperative urination training duringperioperative period (intravenous fluid volume controls in about 1 500 mL on the day of surgery) in the TKA patients are good for postoperationurination.
It also can reduce the rate of postoperative urinary retention,reduce hospital stays and enhance rehabilitation.
