Compared with the N group, the incidence of TH in the L group was significantly decreased (37.5 per cent (18 of 48) Tourniquet hypertension and adverse reactionsValues are Analysed using independent-sample Throughout the study interval, the SBP, DBP or MAP were not significantly different at any time points between the two groups (Haemodynamic characteristics
The degree of elevation of blood pressureDBP, diastolic blood pressure; L group, lidocaine group; N group, normal saline group; SBP, systolic blood pressure; *compared with N group, The plan was to draw blood samples from all enrolled patients, however, some patients declined to have blood drawn or missed some time points of blood samples. In addition, some samples were haemolysed. Finally, there were 26 patients with a full set of blood samples for analysis of IL-6 and TNF-α. No difference was found in the concentration of IL-6 between the two groups at TInflammatory factors in venous bloodL, lidocaine; N, normal saline; IL-6, interleukin 6; TNF-α, tumour necrosis factor-α; TAnalysed using Mann–Whitney The NRS of the L group was significantly lower than that of the N group (Postoperative pain scoresNumerical rating scale: 0, no pain; 10, the most severe pain.
