Pericapsular nerve group (PENG) block combined with local infiltration analgesia is not superior to local infiltration analgesia for the management of postoperative pain after primary elective total hip arthroplasty: A prospective, randomized, controlled, single-blind trial. Heliyon 2024; 10:e33766. [PMID: 39071707 PMCID: PMC11279254 DOI: 10.1016/j.heliyon.2024.e33766] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/03/2023] [Revised: 06/26/2024] [Accepted: 06/26/2024] [Indexed: 07/30/2024] Open
Abstract
Background Local infiltration analgesia (LIA) has been advocated for the pain management after total hip arthroplasty (THA). The analgesic benefits of an added pericapsular nerve group (PENG) block remain questionable. Methods This randomized, single-blind trial enrolled patients undergoing elective THA under general anaesthesia and standardized postoperative analgesia. Patients were allocated to receive either a PENG block (20 mL of ropivacaine 0.475 %) combined with intraoperative LIA (PENG + LIA group, n = 32), or intraoperative LIA alone (LIA group, n = 32). The primary outcome was oral morphine equivalent (OME) consumption at day 1. Secondary outcomes were: pain scores at post anaesthesia care unit (PACU) discharge and on day 2, times for the Timed to Up and Go (TUG) test and measurement of adductor strength on day 1, and patients' satisfaction using the EVAN-G questionnaire. Results Compared with LIA alone, PENG + LIA resulted in similar OME consumption on day 1 (78 [51-91.5] mg vs 58 [30-80] mg respectively, median difference (95%CI) of -17 (-34 to 1) mg, p = 0.09). Pain scores and morphine consumption were not different between groups at any time point. TUG and thigh adduction tests were similar between LIA and PENG + LIA groups (respectively 35 [25-48.5] vs 31.5 [19.5-46.5] sec, p = 0.39; and 105 [85-150] vs 100 [80-125] mmHg, p = 0.61). No difference in the patients' satisfaction was found. Conclusion The addition of a PENG block to large-volume LIA did not significantly improve the analgesia for elective THA in the setting of an adequate basic postoperative analgesia regimen. The results of the lower limb functional tests confirmed the PENG block to be motor-sparing.

Abstract
Objective To compare the effect of sciatic nerve block (SNB) combined with continuted femoral nerve block (FNB) or continuted adductor canal block (ACB) on pain and motor function after total knee arthroplasty (TKA). Methods A total of 60 patients with TKA-treated osteoarthritis of the knee who met the selection criteria were enrolled between November 2020 and February 2021 and randomised allocated into the study group (SNB combined with continuted ACB) and the control group (SNB combined with continuted FNB), with 30 cases in each group. There was no significant difference in gender, age, body mass, height, body mass index, preoperative Hospital for Special Surgery (HSS) score, femoral tibial angle, and medial proximal tibial angle between the two groups ( P>0.05). The operation time, the initial time to the ground, the initial walking distance, and the postoperative hospital stay were recorded. At 2, 4, 6, 12, 24, and 48 hours after operation, the numerical rating scale (NRS) score was used to evaluate the rest pain around the knee joint, the quadriceps femoris muscle strength was evaluated by the freehand muscle strength method, and the knee flexion and extension angles were measured. Results There was no significant difference in the operation time and initial walking distance between the two groups ( P>0.05); the initial time to the ground and postoperative hospital stay of the study group were significantly shorter than those of the control group ( P<0.05). Except for the 48-hour postoperative NRS score of the study group, which was significantly lower than that of the control group ( P<0.05), there was no significant difference in the NRS scores between the two groups at the remaining time points ( P>0.05). The quadriceps femoris muscle strength from 4 to 24 hours postoperatively and the knee extension angle from 2 to 6 hours postoperatively of the study group were significantly better than those of the control group ( P<0.05); the differences in the quadriceps femoris muscle strength and knee extension and flexion angles between the two groups at the remaining time points were not significant ( P>0.05). Conclusion SNB combined with either continuted ACB or continuted FNB can effectively relieve pain in patients after TKA, and compared with combined continuted FNB, combined continuted ACB has less effect on quadriceps femoris muscle strength, and patients have better recovery of knee flexion and extension mobility.

Knee Surg Relat Res 2024; 36:11. [PMID: 38459532 PMCID: PMC10924359 DOI: 10.1186/s43019-024-00215-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/09/2023] [Accepted: 02/20/2024] [Indexed: 03/10/2024] Open
Abstract
INTRODUCTION Mechanical falls represent a potential adverse event after total knee arthroplasty (TKA) and may introduce further injury and delay postoperative recovery. This study aimed to identify patient characteristics associated with inpatient falls, to determine the impact of inpatient falls on surgical outcomes following TKA, and to describe the relationship between tourniquet and/or adductor canal block (ACB) use and fall rates. METHODS Patients undergoing primary, elective TKA at a single institution between 2018 and 2022 were retrospectively analyzed. Patients were stratified into groups based on whether they sustained a postoperative inpatient fall or not. Perioperative characteristics, lengths of stay (LOS), rates of 90-day readmissions, and revisions were compared, and fall characteristics were described. Subanalysis was conducted comparing fall incidence based on tourniquet and/or ACB use. RESULTS In total 6472 patients were included with 39 (0.6%) sustaining falls. Falls most commonly occurred on postoperative days one (43.6%) and two (30.8%), and were most commonly due to loss of balance (41.9%) or buckling (35.5%). Six (15.4%) fall patients sustained minor injuries, and one (2.6%) sustained major injury (malleolar fracture requiring non-operative orthopaedic management). The LOS (3.0 ± 1.5 vs 2.3 ± 1.5 days, p = 0.002) and all-cause revision rates at latest follow-up (10.3% vs. 2.0%, p = 0.008) were significantly higher in the fall group. Falls were comparable across subgroups based on tourniquet and/or ACB use (p = 0.429). CONCLUSION Patients who fell had a longer LOS and higher revision rate postoperatively. Rates of inpatient falls were comparable regardless of tourniquet and/or ACB use. Concern for inpatient falls should not influence surgeons when considering the use of tourniquets and/or ACBs, though well-designed, large-volume, prospective randomized studies are warranted to better understand this relationship.

Blood-conserving and therapeutic efficacy of intravenous tranexamic acid at different time points after primary total knee arthroplasty with tourniquet application: a randomised controlled trial. BMC Musculoskelet Disord 2023; 24:893. [PMID: 37978365 PMCID: PMC10655351 DOI: 10.1186/s12891-023-07036-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/09/2023] [Accepted: 11/12/2023] [Indexed: 11/19/2023] Open
Abstract
BACKGROUND The use of a tourniquet in combination with tranexamic acid (TXA) not only ensures clear vision, reduces intraoperative blood loss and shortens operative time but also improves cement-bone inter-digitation in total knee arthroplasty (TKA). However, there is no proof whether the blood flow blocking effect of tourniquet affects the antifibrinolytic effect of TXA, and the optimal timing of TXA administration is still unclear. Therefore, this study aims to investigate the effect of the first dose of TXA administered intravenously before tourniquet compression and release in TKA on perioperative blood loss and therapeutic efficacy in patients. METHODS In this double-blind trial, 90 patients undergoing primary TKA were randomised into 2 groups: Group A, patients received intravenous TXA 10 min before tourniquet compression (20 mg/kg) and 3, 6 and 24 h later (10 mg/kg), and Group B, patients were treated the same as those in Group A but received intravenous TXA before tourniquet release. The primary outcomes were changes in blood loss, haemoglobin and haematocrit. Secondary outcomes included operation and tourniquet times, blood transfusion rate, subcutaneous petechiae and circumferential changes in the operated limb, visual analogue scale (VAS) score, hospital for special surgery (HSS) score, length of stay (LOS) postoperatively, complications and patient satisfaction. RESULTS No statistically significant difference was found between the 2 groups with regard to age, sex, weight, body mass index (BMI), Kellgren-Lawrence class, preoperative blood volume, preoperative laboratory values, operation and tourniquet times, transfusion rate, knee circumference, preoperative HSS, or VAS score (P:n.s.). There was no significant difference in intraoperative blood loss (IBL) (52.7 ml vs. 63.4 ml, P = 0.07), hidden blood loss (HBL) (91.4 ml vs. 119.9, P = 0.4) or total blood loss (TBL) (144.1 ml vs. 183.3 ml, P = 0.72) between Groups A and B. Haemoglobin, haematocrit and red blood cell count (RBC) dropped to a low point on postoperative day 3 and then rebounded, returning to normal levels on day 21, and the trend of change between the 2 groups was not statistically significant (P:n.s.). There was no significant difference in subcutaneous ecchymosis incidence, knee swelling rate, HSS score, VAS score, LOS postoperatively, complication rate or patient satisfaction (P:n.s.). CONCLUSION TXA was administered intravenously prior to tourniquet compression could effectively reduce blood loss in patients who had undergone total knee arthroplasty. However, there was no significant difference in knee swelling rate, subcutaneous bruising and petechiae incidence, knee function, complication rate or satisfaction between patients who TXA was given intravenously before tourniquet compression and release in primary TKA.

Abstract
BACKGROUND Anterior quadratus lumborum block (AQLB) is one of the compartment blocks and has recently attracted attention as a new method of analgesia for postoperative hip surgery analgesia. This study aimed to compare the analgesic efficacy of AQLB in patients undergoing primary total hip arthroplasty (THA). METHODS There were 120 patients undergoing primary THA under general anesthesia randomly allocated to receive a femoral nerve block (FNB) or an AQLB. The primary outcome was total morphine consumption over the initial 24-hour postoperative period. Secondary outcomes included the pain score evaluation while at rest and during active and passive motion over the 2 days following surgery and the manual muscle testing of the quadriceps femoris. The numerical rating scale (NRS) score was used for evaluating the postoperative pain score. RESULTS There were no significant differences between the 2 groups concerning morphine consumption within 24 hours after surgery (P = .72). The NRS score at rest and passive motion were similar at all-time points (P > .05). However, there was a statistically significant difference in pain reported during the active motion for the FNB group compared to the AQLB (P = .04). No significant differences were found between the 2 groups concerning muscle weakness incidence. CONCLUSION Both AQLB and FNB demonstrated adequate efficacy for postoperative analgesia at rest in THA. However, based on our study, whether AQLB is inferior or noninferior to FNB as an analgesic method for THA was inconclusive.

Abstract
Reducing pain and opioid consumption after total knee arthroplasty (TKA) is an important perioperative consideration. Though commonly used, the combined influence of tourniquets and adductor canal blocks (ACBs) on pain and opioid consumption is unknown. This study evaluated inpatient opioid consumption and pain between patients with TKA based on tourniquet and/or ACB use. Pain and opioid consumption were highest when a tourniquet, but no ACB was used, and lowest when an ACB, but no tourniquet was used - though absolute differences in pain scores were not clinically significant. Tourniquet and ACB use should be considered as part of TKA opioid-sparing protocols.

Abstract
BACKGROUND The perfusion index (PI) is an objective method used to determine a successful nerve block. This study aimed to investigate the prognostic ability of the PI for a successful adductor canal nerve block (ACB) and suggest the optimal PI cut-off value for predicting a block. METHODS This study was a prospective observational study and enrolled a total of 39 patients. The patients were dichotomized into successful and inappropriate ACB groups according to the results of the sensation tests. The PI value, Pleth variability index (PVi) value, and heart rate were recorded one minute before the block, at the time of the block, and one to 30 min after the block at one-minute intervals. Delta (dPI), which was defined as the difference in PI value from the baseline (the value one minute before the block), was the primary outcome. The area under the receiver operating characteristic curve (AUROC) was calculated to determine the dPI prognostic accuracy and optimal cut-off value. RESULTS Successful ACB was achieved in 33 patients, while ACB was inappropriate in six patients. The dPI showed significant differences between the two groups under the time interval measured (p = 0.001). The dPI at 5 and 20 min showed good prognostic ability for a successful block, with optimal cut-off values of 0.33 (AUROC: 0.725, 95% CI 0.499-0.951) and 0.64 (AUROC: 0.813, 95% CI 0.599-1.000), respectively. CONCLUSIONS The dPI is an effective predictor of successful ACB. The suggested dPI cut-off values at 5 and 20 min were below 0.33 and 0.64, respectively.

Risk and Influence Factors of Fall in Immobilization Period after Arthroscopic Interventions. J Pers Med 2022; 12:jpm12111912.

Abstract
Knee injuries are one of the most common injuries. Falls during the immobilization period can deteriorate the postoperative outcome. The risk factors causing falls after initial injury and the question of whether a rigid orthosis serves as a protective factor remain unclear. The primary aim of the study was to record the fall rate in the first six weeks after arthroscopic intervention. The secondary aim was to assess the influences of risk factors and protective factors on these fall ratios. Different scores were examined and compared in the groups ‘fall event’ and ‘no fall’. Data from 51 patients (39 males, 12 females) with a mean age of 31.2 years (19–57 years) were collected. A total of 20 patients suffered at least one fall event within the observation period. A total of 18 of 23 fall events happened within the first three weeks postoperatively. The Extra Short Musculoskeletal Function Assessment Questionnaire (XSMFA) showed a significant difference between the groups (p = 0.02). People with multiple injuries to the knee joint were more likely to suffer fall events. Conclusively, patients with limited knee functions appeared to fall more frequently within the first three weeks postoperatively. Therefore, appropriate measures should be taken to protect the postoperative outcome. Physical therapy and patient behavioural training should be practiced perioperatively in patients at risk.

Abstract
Objective To investigate the clinical application of preoperative adductor canal block combined with general anaesthesia in elderly patients with total knee arthroplasty. Methods Seventy-four patients scheduled for elective TKA in Shaanxi Nuclear Industry Hospital No. 215 were selected and were assigned into group A (continuous ACB prior to the induction of anaesthesia) and group B (continuous ACB after extraction of the tracheal catheter post-operatively) according to the random number table method. Pre and postoperative plasma adrenaline and noradrenaline levels were measured; mean arterial pressure (MAP) and heart rate (HR) were recorded at the admission and the surgical skin incision; intraoperative sufentanil dosage, number of analgesic pump presses at 48 h postoperatively; postoperative adverse effects and length of stay were recorded; resting and active VAS pain scores were assessed at 4, 8, 12, 24, and 48 h postoperatively. Results Group B experienced a substantial increase in MAP and HR at the time of surgical skin incision, while group A registered a smaller change and a stable haemodynamic profile (P < 0.05). The plasma adrenaline and norepinephrine concentrations in group B were elevated compared to the preoperative period, differentially with group A. Group A received less intraoperative sufentanil than Group B (P < 0.05). Conclusion Collectively, postoperative resting VAS scores and active VAS scores remained lower in TKA patients who were subjected to preoperative and postoperative ACB, while preoperative ACB in conjunction with general anaesthesia decreased intraoperative sufentanil dosage, contained the surgical stress response, and maintained a stable intraoperative haemodynamic state, in what is probably a preferable option for elderly patients undergoing TKA. This study has served as a reference for postoperative patients to reduce their medication and for clinicians in the treatment going forward.
