Enhanced recovery after surgery (ERAS) pathway for primary hip and knee arthroplasty: study protocol for a randomized controlled trial

A Comparison Between Fondaparinux Sodium and Low-Molecular-Weight Heparin in Preventing Patients Undergoing Hip Replacement from Deep Vein Thrombosis

OBJECTIVES

Total hip arthroplasty (THA) is a highly successful and effective surgery for improving hip functions and relieving pain. However, the lower extremities are prone to deep vein thrombosis (DVT) and swelling after surgery, thereby delaying recovery. In this study, we investigated the preventive effects of fondaparinux sodium (FS) and low-molecular-weight heparin (LMWH) on DVT of the lower extremity after THA.

METHODS

Firstly, 60 patients who underwent THA at the First Affiliated Hospital of Wannan Medical College from March 2020 to December 2020 were included. Next, the patients were randomly divided into an LMWH group (n = 30) and an FS group (n = 30). Then, the indexes related to DVT were compared between both groups.

RESULTS

Specifically, the differences in baseline data, such as age, gender and body mass index (BMI), between the two groups were not statistically significant. The postoperative weight bearing time of patients in the FS group was much shorter than that in the LMWH group.

CONCLUSION

Subcutaneous injection of FS not only exhibits superior effects to LMWH in preventing DVT after THA but also has a correlation with reducing the risk of thrombosis and improving patient symptoms.

Impact of perioperative enhanced recovery after surgery on wound infection in patients undergoing orthopaedic surgery: A meta-analysis

The aim of this study was to evaluate the effects of perioperative application of enhanced recovery after surgery (ERAS) concepts on wound infections and post-operative complications in patients receiving orthopaedic surgery, to provide a theoretical basis for post-operative care. Randomised controlled trials (RCTs) on the application of ERAS to patients receiving orthopaedic surgery, published up to October 2023, were identified in PubMed, Web of Science, Cochrane Library, Embase, Wanfang, China Biomedical Literature Database and China National Knowledge Infrastructure databases. Literature was screened and evaluated by two reviewers based on the inclusion and exclusion criteria, and data were extracted from the final included articles. Data were analysed using RevMan 5.4 software. A total of 20 RCTs were included in the analysis, which included 1875 patients undergoing orthopaedic surgery, of whom 938 and 937 were in the ERAS and control groups, respectively. The analysis revealed that in patients undergoing orthopaedic surgery, implementation of ERAS in the perioperative period was associated with a significantly reduced the rate of wound infections (1.6% vs. 6.19%, risk ratio [RR]: 0.30, 95% confidence interval [CI]: 0.18-0.50, p < 0.001) and complication (5.12% vs. 21.88%, RR: 0.23, 95% CI: 0.17-0.32, p < 0.001) and can effectively shorten the hospital length of stay (standardised mean difference [SMD]: -2.50 days, 95% CI: -3.17 to -1.83 days, p < 0.001) compared with that of conventional care. The available evidence suggests that the implementation of ERAS in the perioperative period of patients undergoing orthopaedic surgery could effectively reduce the rate of wound infections and complications, shorten the hospital length of stay and promote the early recovery of patients.

Prediction of risk factors of sleep disturbance in patients undergoing total hip arthroplasty

The purpose of this study was to assess sleep quality in patients undergoing total hip arthroplasty (THA) from preoperatively to 12 weeks postoperatively and to establish a risk predictor for postoperative sleep disturbance to enable early care and intervention. A self-designed data collection form was used. Patients were assessed preoperatively and at 5 postoperative time points using visual analog scale (VAS) for pain, sleep quality and neuropsychological status with the following assessment tools: the Chinese versions of the Pittsburgh Sleep Quality Index (CPSQI), the Epworth Sleepiness Scale (CESS), the Zung Self-Rating Anxiety Scale (ZSAS) and the Epidemiological Studies Depression Scale (CESD). Univariate and multivariate logistic regression analysis was used for the identification of risk factors for postoperative sleep disturbance. The receiver operating characteristic (ROC) curve was plotted to evaluate the regression model. Of the 290 eligible patients, 193 (133 women) were included in the study. There was a 60.6% prevalence of preoperative sleep disturbance. The CPSQI score increased significantly at 2 weeks postoperatively compared to preoperative baseline, but appeared to decrease at 4 weeks postoperatively. Multivariate logistic regression analysis showed that pain (VAS score: OR = 1.202 [95% CI = 1.002-1.446, P < 0.05]), daytime sleepiness (CESS score: OR = 1.134 [95% CI = 1.015-1.267, P < 0.05]) and anxiety (ZSAS score: OR = 1.396 [95% CI = 1.184-1.645, P < 0.001]) were risk factors associated with postoperative sleep disturbance at 2 weeks. The ROC curve showed that the AUC was 0.762, the sensitivity was 83.19% and the specificity was 64.86%. Postoperative sleep disturbance is highly prevalent in the first 2 weeks after THA. The risk prediction model constructed according to the above factors has good discriminant ability for the risk prediction of sleep disturbance after THA. The use of this risk prediction model can improve the recognition of patients and medical providers and has good ability to guide clinical nursing observation and early screening of sleep disturbance after THA.

Early observations with an ERAS pathway for thyroid and parathyroid surgery: Moving the goalposts forward

BACKGROUND

Enhanced recovery after surgery pathways have become the standard of care in various surgical specialties. In this study, we discuss our initial experience with a staged enhanced recovery after surgery pathway in endocrine surgery and assess the impact of this pathway on select perioperative outcomes and unanticipated admissions.

METHODS

We collected information regarding all thyroid/parathyroid surgeries performed by endocrine surgeons at our institution before and after the implementation of the multi-intervention enhanced recovery after surgery pathway. We compared relevant outcomes for all cases 1 year before (n = 479) and 1 year after (n = 166) implementation of the pathway. We also compared outcomes between enhanced recovery after surgery patient groups with varying levels of enhanced recovery after surgery compliance.

RESULTS

Enhanced recovery after surgery was associated with a significant decrease in total length of stay (9.2 vs 7.5 hours, P < .0001). Whereas there was no significant decrease in all-cause unanticipated postoperative admissions, there was a decrease in patient-initiated admissions in the Enhanced recovery after surgery group. There was also a significant decrease in mean postoperative morphine milligram equivalents (14.4 vs 16.2 vs 24.8, P = .0015), average daily morphine milligram equivalents (25.6 vs 45.6 vs 53, P < .0001), and average daily pain scores (1.89 vs 2.38 vs 2.74, P = .0045) in the Enhanced recovery after surgery group (particularly with increasing Enhanced recovery after surgery compliance). There were no significant differences in the requirement for postoperative antiemetics or in the post-anesthesia care unit length of stay.

CONCLUSION

This study demonstrates a significant benefit from Enhanced recovery after surgery pathways for thyroidectomies and parathyroidectomies, even with initial data and a staggered roll-out plan. Further directions include a follow-up study once we reach a higher level of institutional compliance with all components of the Enhanced Recovery After Surgery pathway and a prospective trial to identify the relative significance of different portions of the Enhanced Recovery after Surgery pathway, particularly the superficial cervical plexus block.

Examining the Efficacy of Drain Tip Cultures in Predicting Postoperative Surgical Site Infections in Hip Arthroplasty: A 15-Year Retrospective Study

Background Postoperative surgical site infections (SSIs) are a significant complication of surgical procedures, leading to increased morbidity, prolonged hospital stays, and substantial healthcare costs; however, the use of drain tip cultures to diagnose SSIs in patients is controversial. The objective of this study was to evaluate the efficacy of drain tip cultures for the prediction of postoperative SSIs in patients recovering from hip arthroplasty. Methodology The data were collected from 1204 patients who underwent hip arthroplasty procedures over 15 years, and statistical analysis was performed to evaluate the diagnostic value of drain tip culture in determining surgical site infection. We also used these data to evaluate whether preexisting conditions such as hypertension or diabetes affected the probability of a patient getting an SSI. Results Drain tip cultures were positive in 12 of 1,112 cases of primary hip arthroplasty, but only one of these 12 patients was ultimately diagnosed with an SSI (sensitivity, 12.5%; specificity, 99.0%; p = 0.0834). Results from postoperative drain tip cultures performed in patients undergoing revision arthroplasty included two false positives and three false negatives; interestingly, no true positives were detected in any of the revision arthroplasty cases we evaluated (sensitivity, 0％; specificity, 97.8％; p = 0.9355). Conclusion Our results indicate that drain tip cultures have no statistically significant predictive value for the diagnosis of postoperative SSIs and thus should not be used as a primary diagnostic or predictive tool for SSIs. We recommend exploring other diagnostic tools for the postoperative diagnosis of SSIs. Standardized guidelines should therefore be established to improve the predictive value of the different methods.

[Effect of enhanced recovery after surgery on postoperative function and pain in total hip arthroplasty patients with high comorbidity]

Objective

To investigate the effects of enhanced recovery after surgery (ERAS) on postoperative function and pain in total hip arthroplasty (THA) patients with high comorbidity.

Methods

Patients with THA who were admitted between January 2020 and January 2022 were selected as the study objects, and a total of 223 patients with high comorbidity met the selection criteria. Patients were randomly divided into two groups using the random envelope method. During perioperative period, 112 cases in the ERAS group were treated according to the ERAS protocol and 111 cases in the control group with the traditional protocol. There was no significant difference in gender, age, body mass index, Charlson comorbidity index, preoperative diagnosis, the type and number of the comorbidities, preoperative visual analogue scale (VAS) score between the two groups ( P>0.05). However, the Harris score of ERAS group was significantly lower than that of control group before operation ( P<0.05). Preoperative and postoperative hospital stays were recorded. The VAS score was used to evaluate the pain before operation, at 1 day after operation, at the leaving bed time, at the day after discharge, and at 2 weeks after operation. Harris score was used to evaluate hip function before operation and at 2 weeks, 1 month, 3 months, 6 months, and 12 months after operation. The incidence of complications, 30-day readmission rate, mortality rate, and patient's satisfaction were recorded.

Results

The length of preoperative hospital stay in ERAS group was significantly shorter than that in control group ( P<0.05). But there was no significant difference in the length of postoperative hospital stay between groups ( P>0.05). All patients in the two groups were followed up 12 months. The VAS score in the two groups after operation was lower than that before operation, and showed a gradually trend with the extension of time, with significant differences between different time points ( P<0.05). VAS scores of ERAS group were significantly lower than those of control group at different time points after operation ( P<0.05). The postoperative Harris scores in both groups were higher than those before operation, and showed a gradually increasing trend with the extension of time, with significant differences between different time points ( P<0.05). Harris scores of ERAS group at 2 weeks, 1 month, and 3 months after operation were significantly higher than those of control group ( P<0.05). Complications occurred in 2 cases (1.79%) of the ERAS group and 6 cases (5.41%) of the control group, with no significant difference in incidence ( P>0.05). In the control group, 1 case was readmitted within 30 days after operation, and 1 case died of severe pneumonia within 1 year of follow-up. There was no readmission or death in ERAS group, and there was no significant difference in the above indexes between the two groups ( P>0.05). At last follow-up, the satisfaction rate of patients in ERAS group was slightly higher than that in control group, but the difference was not significant ( P>0.05).

Conclusion

For THA patients with high comorbidity, ERAS protocol can shorten preoperative waiting time, better reduce pain, and improve hip function.

Positive Preemptive Analgesia Effectiveness of Pregabalin Combined with Celecoxib in Total Knee Arthroplasty: A Prospective Controlled Randomized Study

Objective

The purpose of the present study (a randomized clinical trial) was to evaluate the preemptive analgesic effects of pregabalin combined with celecoxib in total knee arthroplasty (TKA).

Methods

From January 2019 to June 2021, we enrolled 149 patients who underwent TKA and divided them into four groups: the placebo group (n = 36), celecoxib group (n = 38), pregabalin group (n = 38), and combination group (n = 37). Each group was given the corresponding preemptive analgesia regimen at 12 and 2 hours before surgery. The pain score at rest and upon movement, cumulative dosage of sufentanil, knee range of motion (ROM), high-sensitivityC-reactive protein (hs-CRP) level, and adverse effects were evaluated after TKA to compare the effects of the preemptive analgesia regimens among the four groups.

Results

The pain scores upon movement were significantly lower in the combination group than in the other three groups at 6, 12, 24, and 48 hours after surgery (P < 0.05). The cumulative dose of sufentanil within 48 hours after surgery was lowest in the combined group among the four groups (P < 0.05). Hs-CRP, ROM, and postoperative nausea and vomiting (PONV) were within 72 hours after surgery significantly improved in the combination group compared with those of the three other groups (P < 0.05).

Conclusion

The preemptive analgesia regimen of pregabalin combined with celecoxib had positive effects on improving acute pain and reducing the cumulative dose of opioids after TKA. This trial is registered with ChiCTR2100041595.

The Comparison between Mini-Subvastus Approach and Medial Parapatellar Approach in TKA: A Prospective Double-Blinded Randomized Controlled Trial

Objective

Minimal invasive approach has been increasingly used in total knee arthroplasty (TKA) and more is expected of early rehabilitation in terms of pain release and recovery of knee function. The approach type is one of the major factors that determines the early rehabilitation after TKA. The purpose of this study is to determine whether mini‐subvastus approach (MSVA) is superior to the traditional medial parapatellar approach (MPA) in TKA.

Methods

From 2018 to 2019, a randomized double‐blinded prospective study was conducted on 58 patients who underwent simultaneous bilateral TKA. The subjects included eight men and 50 women, with an average age of 65 years. One side was randomized using MSVA and the other side using MPA. Visual analog scale (VAS), operative duration, recovery time to straight leg raising (SLR), range of motion (ROM), HSS score, release rate of lateral retinaculum, satisfaction rate were recorded and compared. Paired‐samples T test were used for quantitative data and chi‐square test for qualitative data.

Results

There was no statistical difference in the ratio of left and right sides, preoperative ROM, VAS, HSS score, muscular strength of lower limbs, KL grade, operative order, and operative duration between the two groups. The average ROM (118.91 ± 8.21 vs. 107.60 ± 7.99, t = 14.320, p = 0.0000) and HSS score (72.03 ± 4.55 vs. 61.22 ± 4.36, t = 13.095, p = 0.0000) on POD 3, VAS in rest and motion on POD 1 and 3, the recovery time to SLR (1.17 ± 0.38 vs. 3.09 ± 0.76, t = 19.902, p = 0.0000), and the satisfaction rate on POD 1 (96.55% vs. 74.14%, χ² = 9.9251, p = 0.0016) were superior in the MSVA group over MPA group. ROM in rest and motion and HSS score on POD 30 had no difference. The release rate of lateral retinaculum was less in the MSVA group than in the MPA group. The mean value of HKA, FFC, and FTC and the proportion of outliers did not differ significantly between the two groups.

Conclusions

Compared with MPA, MSVA can make ROM of knee and SLR recover earlier, reduce postoperative pain after TKA, improve the early postoperative satisfaction and reduce the lateral release rate. MSVA can be used as a favorable measure in the concept of enhanced recovery after surgery (ERAS).

A new cocktail formula with diprospan of local infiltration analgesia in primary total hip arthroplasty: A prospective, randomized, controlled, observer-blinded study

OBJECTIVE

This study aimed to observe the analgesic effect of the cocktail formulation with diprospan during total hip arthroplasty (THA).

METHODS

From September 2018 to April 2019, 120 patients undergoing primary unilateral THA were included in this prospective, randomized, observer-blinded study. Patients were randomized into three groups, according to the different local infiltration analgesia (LIA) strategies: LIA with ropivacaine (the ropivacaine group, n = 40), LIA with a new cocktail containing ropivacaine, diprospan, and morphine (the cocktail group, n = 40), and the control group (n = 40). The primary outcomes included postoperative pain scores. The resting visual analogue scale (VAS) scores were measured at 2, 6, and 12 h after the surgery (a.m. and p.m.) on postoperative day (POD) 1, POD2, and the day of discharge. Movement VAS scores were assessed at 6 h, 12 h after the operation (a.m. and p.m.) on POD1, POD2, and the day of discharge. The secondary outcomes included opioid consumption, postoperative hospital stay, range of motion of the hip at discharge, patient satisfaction, and the results of the follow-up.

RESULTS

After the screening, 120 patients were randomized into three groups (40 patients in each group). All of the patients completed the trial. The resting VAS scores in the ropivacaine group and cocktail group at 2 h were lower than those in the control group (P < 0.001 and P < 0.001, respectively, F = 17.054), and the same trend was also postoperatively found at 6 h (p = 0.005 and P = 0.002, F = 6.212). Twelve hours after the operation, the pain score in the cocktail group was lower than that in the other two groups, but only the difference between the cocktail group and the control group was statistically significant (P = 0.018, F = 3.144). From the morning of the first postoperative day to the a.m. on POD 2, the VAS scores in the cocktail group were significantly lower than those in the ropivacaine group and the control group. Furthermore, the movement VAS scores in the ropivacaine group and the cocktail group were better than those in the control group at 6 and 12 h post-operation (P < 0.05). The per capita opioid consumption in the cocktail group was less than that in the ropivacaine group and the control group within 24 h post-operation. There were no significant differences in the comparison of additional indicators among the three groups.

CONCLUSION

The new cocktail with diprospan had a better result and longer duration time for early postoperative pain control in primary THA via the posterolateral approach under general anesthesia, especially for treating resting pain.

Correlation of patient-reported numbness around surgical scars with patient-reported outcome measures and joint awareness after knee replacement: a cohort study

Background

Knee replacement is a very effective and indispensable treatment option for end-stage knee arthritis, and the number of cases has been increasing worldwide. A replaced knee joint without patient joint awareness is thought to be the ultimate goal of artificial knees. Joint awareness reportedly correlates with patient satisfaction. Although numbness around a replaced knee is a minor but common problem, its effect on postoperative outcome is controversial. Joint awareness also is sensitive to subtle abnormalities of the joint, so it must be negatively affected by numbness. Although numbness is minor, it cannot be ignored to further improve knee replacement outcomes. This study investigated the relationship between patient-reported numbness and other patient-reported outcome measures (PROMs), including joint awareness, and kneeling. We developed a numbness score based on a 5-point Likert scale on frequency of numbness, with an intraclass correlation coefficient of 0.76 and higher scores indicating less numbness.

Methods

The numbness score, New Knee Society Score (KSS), Knee Injury and Osteoarthritis Outcome Score (KOOS), Forgotten Joint Score-12 (FJS-12), and other clinical and radiological data from 311 patients (394 primary knee replacements) were analyzed. Kneeling ability was evaluated by using kneeling-specific items in the KSS (KSS-Kneeling).

Results

No numbness was found in 170 knees (43.1%), and some degree of numbness was found in the remaining 224 knees (56.9%). The numbness score showed weak-to-moderate correlations with KSS-Symptoms (r = 0.44), KSS-Satisfaction (r = 0.41), KSS-Activities (r = 0.29), and all KOOS subscales (r = 0.23–0.44), and FJS-12 (r = 0.42). Multiple regression analyses suggested that midline incision positively affected the numbness score over the anteromedial incision (p = 0.04) and that a better numbness score (p = 0.001), male sex (p < 0.0001), and better postoperative knee flexion angle (0.04) positively affected kneeling.

Conclusions

The numbness score positively correlated with PROMs and positively affected kneeling. Knee replacements performed via an anteromedial incision may be at higher risk for numbness.

ERAS Protocols for Thyroid and Parathyroid Surgery: A Systematic Review and Meta-analysis

OBJECTIVE

Enhanced recovery after surgery (ERAS) protocols are evidenced-based multidisciplinary programs implemented in the perioperative setting to improve postoperative recovery and attenuate the surgical stress response. However, evidence on their effectiveness in thyroid and parathyroid surgery remains sparse. Therefore, our goal was to investigate the clinical benefits and cost-effectiveness of ERAS protocols for the perioperative management of thyroidectomy and parathyroidectomy.

DATA SOURCE

A systematic review of Medline, Scopus, Embase, and gray literature was performed to identify studies of ERAS or clinical care protocols for thyroidectomy and parathyroidectomy.

REVIEW METHODS

Two reviewers screened studies using predetermined inclusion criteria. Our primary outcomes included hospital length of stay and hospital costs. Readmission and postoperative complication rates composed our secondary outcomes. Meta-analysis was performed to compare outcomes for patients enrolled in the ERAS protocol versus standard of care.

RESULTS

A total of 450 articles were identified; 7 (1.6%) met inclusion criteria with a total of 3082 patients. Perioperative components in ERAS protocols varied across the studies. Nevertheless, patients enrolled in ERAS protocols had reduced hospital length of stay (mean difference, -0.64 days [95% CI, -0.92 to -0.37]) and hospital costs (in US dollars; mean difference, -307.70 [95% CI, -346.49 to -268.90]), without an increase in readmission (odds ratio, 0.75 [95% CI, 0.29-1.94]) or complication rates (odds ratio, 1.14 [95% CI, 0.82-1.57]).

CONCLUSION

There is growing literature supporting the role of ERAS protocols for the perioperative management of thyroidectomy and parathyroidectomy. These protocols significantly reduce hospital length of stay and costs without increasing complications or readmission rates.

The deep vein thrombosis of lower limb after total hip arthroplasty: what should we care

Background

Deep vein thrombosis (DVT) of lower limb is one of the common complications after total hip arthroplasty(THA), we aimed to evaluate the potential risk factors of DVT of lower limb in patients with THA, to provide insights into the management of THA.

Methods

Patients who underwent THA in our hospital from January 1, 2017 to November 30, 2020 were included. The personal characteristics and clinical data of DVT and no-DVT patients were compared and analyzed. Logistic regression analyses were perfomed to identify the potential risk factors of DVT in patients with THA.

Results

A total of 182 THA patients were included, the incidence of DVT of lower limb in patients with THA was 19.78 %. There were significant differences in the age, BMI, diabetes, number of replacement, duration of surgery, type of prosthesis and duration of days in bed between DVT and no-DVT patients(all P < 0.05). And there were no significant differences in the gender, hypertension, hyperlipidemia, preoperative D-dimer, type of anesthesia and anticoagulant drugs use(all P > 0.05). Logistic regression analysis indicated that age > 70y(OR4.406, 95 %CI1.744 ~ 6.134), BMI ≥ 28(OR2.275, 95 %CI1.181 ~ 4.531), diabetes(OR3.949, 95 %CI1.284 ~ 5.279), bilateral joint replacements(OR2.272, 95 %CI1.402 ~ 4.423), duration of surgery ≥ 120 min(OR3.081, 95 %CI1.293 ~ 5.308), cemented prosthesis(OR2.435, 95 %CI1.104 ~ 4.315), and duration of days in bed > 3 days(OR1.566, 95 %CI1.182 ~ 1.994) were the risk factors of DVT of lower limb in patients with THA.

Conclusions

DVT in the lower limb after THA is common, and its onset is affected by many factors. In clinical work, attention should be paid to identify the risk factors for DVT and targeted interventions are highlighted to prevent the postoperative DVT.

Natural outcome of hemoglobin and functional recovery after the direct anterior versus the posterolateral approach for total hip arthroplasty: a randomized study

BACKGROUND

Total hip arthroplasty (THA) is one of the most successful orthopedic surgeries. There are many common surgical approaches for THA. The direct anterior approach (DAA) and posterolateral approach (PLA) were compared, leading to controversial results.

METHODS

We report on a prospective randomized study which compared the changes of perioperative hemoglobin (Hb), the Harris hip score (HHS) and a visual analog scale (VAS) pain score following THA using DAA or PLA. A total of 130 participants were randomly divided into two groups (65 DAA versus 65 PLA). Perioperative ΔHb and other clinical outcomes were recorded.

RESULTS

A total of 130 participants completed follow-up, while 14 patients were not recorded in blood outcomes due to blood transfusions and complications. The average Hb decrease immediately after surgery in the DAA group was greater than that in the PLA group (21.1 versus 15.8 g/L, P < .001). However, post-operative Hb descent velocity was slower in the DAA group, and the lowest point was reached earlier. No significant differences in ΔHb levels could be observed after 1 month in the two groups. When compared with the PLA group, the DAA group had a shorter incision (9.1 versus 13.5 cm, P < .001) and shorter hospital stay (4.2 versus 4.7 days, P = .004). However, the operation time of the DAA group was longer (88.0 versus 66.8 min, P < .001). The DAA group had a better HHS and VAS pain score at 6 weeks post-surgery. However, no significant differences were observed at later time points.

CONCLUSION

We concluded that DAA performed better on enhanced recovery after surgery (ERAS) than PLA in THA, while both DAA and PLA could result in a positive, similar result after 3 months.

TRIAL REGISTRATION

The study was registered by the Chinese Clinical Trial Registry (ChiCTR1900020770, 19 January 2019).
