Abstract:
Objective To compare the perioperative immune function after ultrasound guided continuous adductor canal block (CACB) alone and CACB combined with periarticular local infiltration analgesia (PLIA) in patients undergoing total knee arthroplasty (TKA).
Methods Sixty patients in Changzhi City People′s Hospital from June to December 2018 undergoing TKA under general anesthesia were randomly divided into either a CACB alone group or CACB combined with PLIA group (PLIA group), with 30 cases in each group. Blood samples were assessed for the proportions of CD3+ , CD4+ , and NK cells as well as CD4+ /CD8+ ratio before surgery (T1) and 2 h (T2), 12 h (T3), 24 h (T4), and 48 h (T5) after surgery.
Results Compared with T1, the levels of CD3+ , CD4+ , CD4+ /CD8+ ratio, and NK cells declined significantly in both groups at all time points after surgery (P<0.05). Compared with the CACB group, the levels of CD3+ , CD4+ , CD4+ /CD8+ , and NK cells at T2-T4 in the PLIA group were significantly higher (P<0.05).
Conclusion CACB combined with PLIA can more significantly reduce postoperative knee joint pain, relieve passive movement pain, shorten passive movement time, and promote the patients' early movement and function recovery by reducing the suppression of immune function.
