Abstract


Objective: To evaluate the clinical effects of single femoral nerve block (sFNB) combined with general anesthesia on geriatric patients receiving unilateral total knee arthroplasty (UTKA).

Methods: Sixty geriatric UTKA patients who were treated in The First People’s Hospital of Changzhou from January 2015 to August 2015 were randomly divided into an sFNB + laryngeal mask airway (FLA) group, an sFNB + tracheal intubation (FGA) group and a tracheal intubation (GA) group. Their clinical parameters and indices were recorded. They were scored by the Visual Analogue Scale (VAS).

Results: All patients completed this study. FLA and FGA groups used less propofol, remifentanil and fentanyl than GA group (P<0.01), with shorter recovery time and extubation time (P<0.05). Compared to GA group, FLA and FGA groups had lower systolic blood pressures at T3, T4 and T5 (P<0.05), and lower heart rates at T5 (P<0.05). FLA and FGA groups had fewer cases of adverse reactions after extubation (P<0.01). FLA group was less prone to irritating cough after extubation and pharyngeal pain than FGA and GA groups (P<0.01). The postoperative six hour  and 24 hour VAS scores in resting state as well as the postoperative 24 hour and 48 hour scores in training state of FLA and FGA groups were lower than those of GA group (P<0.05). FLA and FGA groups used significantly lower times and total doses of patient-controlled intravenous analgesia pump.

Conclusion: sFNB combined with general anesthesia, especially that using laryngeal mask, were superior to general anesthesia alone, which reduced recovery and extubation times, and decreased intraoperative and postoperative drug uses, postoperative early VAS score and adverse reactions.
