Negative pressure wound therapy compared with conventional wound dressings for closed incisions in orthopaedic trauma surgery: A meta‐analysis

We performed a meta‐analysis to evaluate the effect of negative pressure wound therapy compared with conventional wound dressings on closed incisions in orthopaedic trauma surgery. A systematic literature search up to October 2021 was done and 12 studies included 3555 subjects with closed incisions in orthopaedic trauma surgery at the start of the study: 1833 of them were provided with negative pressure wound therapy and 1722 were conventional wound dressings. They were reporting relationships about the effect of negative pressure wound therapy compared with conventional wound dressings on closed incisions in orthopaedic trauma surgery. We calculated the odds ratio (OR) and mean difference (MD) with 95% confidence intervals (CIs) to assess the effect of negative pressure wound therapy compared with conventional wound dressings on closed incisions in orthopaedic trauma surgery using the dichotomous and continuous methods with a random or fixed‐effect model. Negative pressure wound therapy had significantly lower deep surgical site infection (OR, 0.65; 95% CI, 0.48–0.88, P = .005), superficial surgical site infection (OR, 0.23; 95% CI, 0.11–0.49, P = .31), and wound dehiscence (OR, 0.41; 95% CI, 0.21–0.80, P = .009) compared with conventional wound dressings in subjects with closed incisions in orthopaedic trauma surgery. However, negative pressure wound therapy had no significant effect on the length of hospital stay (MD, 0.29; 95% CI, −2.00‐ 2.58, P = .80) compared with conventional wound dressings in subjects with closed incisions in orthopaedic trauma surgery. Negative pressure wound therapy had significantly lower deep surgical site infection, superficial surgical site infection, and wound dehiscence; however, negative pressure wound therapy had no beneficial effect on the length of hospital stay compared with conventional wound dressings in subjects with closed incisions in orthopaedic trauma surgery. Further studies are required to validate these findings.     

A systemic review and a meta-analysis on the influences of closed incisions in orthopaedic trauma surgery by negative pressure wound treatment compared with conventional dressings

We performed a meta-analysis to evaluate the influences of closed incisions in orthopaedic trauma surgery (OTS) by negative pressure wound treatment (NPWT) compared with conventional dressings. A systematic literature search up to March 2022 was done and 14 studies included 3935 subjects with OTS at the start of the study; 2023 of them used NPWT and 1912 were conventional dressings. They were reporting relationships between the influences of closed incisions in OTS by NPWT compared with conventional dressings. We calculated the odds ratio (OR) with 95% confidence intervals (CIs) to assess the influences of closed incisions in OTS by NPWT compared with conventional dressings using the dichotomous methods with a random or fixed-effect model. NPWT had significantly lower deep surgical site infections (SSIs) (OR, 0.65; 95% CI, 0.48-0.87, P = .004), superficial SSIs (OR, 0.34; 95% CI, 0.19-0.61, P < .001), and wound dehiscence (OR, 0.41; 95% CI, 0.21-0.80, P = .009) compared with conventional dressings in subjects with closed incisions in OTS. NPWT showed a beneficial effect on deep SSIs, superficial SSIs, and wound dehiscence compared with conventional dressings in subjects with closed incisions in OTS. Further studies are required to validate these findings.

Intrawound vancomycin powder in orthopaedic surgery as surgical site wound infection prophylaxis: A meta-analysis

A meta-analysis research was executed to appraise the consequence of intrawound vancomycin powder (IWVP) in orthopaedic surgery (OPS) as surgical site wound infection (SSWI) prophylaxis. Inclusive literature research till March 2023 was carried out and 2756 interconnected researches were revised. Of the 18 picked researches enclosed 13 214 persons with OPS were in the used researches' starting point, 5798 of them were utilising IWVP, and 7416 were control. Odds ratio (OR) in addition to 95% confidence intervals (CIs) were used to appraise the consequence of the IWVP in OPS as SSWI prophylaxis by the dichotomous approaches and a fixed or random model. IWVP had significantly lower SSWIs (OR, 0.61; 95% CI, 0.50-0.74, P < .001), deep SSWIs (OR, 0.57; 95% CI, 0.36-0.91, P = .02), and superficial SSWIs (OR, 0.67; 95% CI, 0.46-0.98, P = .04) compared with control in persons with OPS. IWVP had significantly lower SSWIs, deep SSWIs, and superficial SSWIs compared with control in persons with OPS. However, when interacting with its values, caution must be taken and more research is needed to confirm this finding.     

The effect of liposomal bupivacaine for surgical wound infiltration: A meta-analysis of randomised controlled trials

Liposomal bupivacaine (LB) has consistently been considered a potential analgesic for surgical wound infiltration. However, the evidence of its analgesic effectiveness remains unclear. In this meta-analysis, we attempted to identify the potential clinical role of LB wound infiltration in different surgical procedures. Randomised controlled trials (RCTs) comparing LB with non-liposomal local anaesthetics and placebos were retrieved from six electronic databases. The primary outcome was cumulative morphine equivalent consumption within 24, 48, and 72 hours after surgery. Approximately 2659 patients from 22 studies were included in the meta-analysis. Compared to the control, LB-wound infiltration did not reduce the postoperative morphine consumption at 24 hours (weighted mean difference [WMD], −0.60 mg; 97.5% confidence interval [CI], −2.78 to 1.59 mg; P = 0.54), 48 hours (WMD, −1.00 mg; 97.5% CI, −3.23 to 1.24; P = 0.32) or 72 hours (WMD, 0.50 mg; 97.5% CI, −0.67 to 1.67; P = 0.33). Similarly, secondary outcome analysis did not reveal any additional benefits of LB in any other pain-related outcomes. LB was not associated with any adverse effects. Overall, LB does not appear to improve the postoperative analgesic, rehabilitation, or safety outcomes. Current evidence does not support the routine use of LB for wound infiltration following surgical procedures.     

Impact of negative pressure wound treatment on incidence of surgical site infection in varied orthopedic surgeries: A systematic review and meta-analysis

Negative pressure wound therapy (NPWT) is a popular treatment to heal infected wounds. This meta-analysis aimed to determine if NPWT was more effective than conventional wound dressings for surgical site infections (SSI) in varied orthopaedic surgeries. Literature was retrieved from seven electronic databases (Medline, Web of Science, PubMed, Embase, Google Scholar, Cochrane Library, and CNKI). Randomised control trials (RCT) and retrospective cohort studies (RS) involving arthroplasty, fracture, and spinal surgery were extracted. SSI was our primary outcome, while total complications and length of hospital stay were secondary outcomes. We carried out the risk of bias assessment and meta-analysis using the Cochrane Risk of Bias 2.0 tool and Stata 17.0. Among the 798 studies retrieved, 18 of them met our inclusion criteria. We identified 13 RCTs and 5 RSs. The results of meta-analysis showed that the incidence of SSI in the NPWT group was significantly lower relative to the control group (OR = 0.60, 95% CI 0.47 to 0.77, P < 0.001). Subgroup analyses revealed that the incidences of SSI involving arthroplasty, fracture, and spinal surgery in the NPWT group accounted for 46%, 69%, and 37% relative to the control group, respectively. The incidence of SSI in RS (OR = 0.27, 95% CI 0.13 to 0.56) was significantly lower than that in RCT (OR = 0.69, 95% CI 0.54 to 0.90) (P = 0.02). Moreover, patients in the NPWT group had a lower total complication rate (OR = 0.51, 95% CI 0.34 to 0.76) and shorter hospital stays (SMD = −0.42, 95% CI −0.83 to −0.02), although high heterogeneity existed. NPWT may be an efficient alternative to help prevent the incidence of SSI and total complications as well as achieved shorten hospital stay in varied orthopaedic surgeries. The rational use of NPWT should be based on the presence of patients' clinical conditions and relevant risk factors.     

Use of local wound infiltration in open hepatectomy to reduce wound pain: A systematic review and meta-analysis

The aim of this study was to assess the effects of local wound infiltration anaesthesia on postoperative wound pain in patients undergoing open liver resection. The Cochrane Library, PubMed, EMBASE, China National Knowledge Infrastructure (CNKI), Chinese Biomedical Literature Database (CBM) and Wanfang databases were searched. The search period spanned from database creation to December 2022. All relevant studies on local wound infiltration anaesthesia for analgesia after hepatectomy were included. Two investigators independently screened the literature, extracted data and evaluated the quality of each study. Review Manager (RevMan) 5.4 software (Cochrane Collaboration) was used for the meta-analysis, in which 12 studies with 986 patients were included. The results show that local wound infiltration anaesthesia effectively reduced surgical site wound pain at 4 h (mean difference [MD]: −1.26, 95% confidence intervals [CIs]: −2.15 to −0.37, P = .005), 12 h (MD: −0.84, 95% CIs: −1.26 to −0.42, P < .001), 24 h (MD: −0.57, 95% CIs: −1.01 to −0.14, P = .009) and 48 h (MD: −0.54, 95% CIs: −0.81 to −0.26, P < .001) postoperatively; however, there was no significant difference in analgesia at 72 h postoperatively (MD: −0.10, 95% CIs: −0.80 to 0.59, P = .77). These findings suggest that local wound infiltration anaesthesia administered to patients undergoing open liver resection provides good postoperative wound analgesia at the surgical site.

Effect of wound protectors in reducing the incidence of surgical site wound infection in lower gastrointestinal surgery: A meta-analysis

We performed a meta-analysis to evaluate the effect of wound protectors in reducing the incidence of surgical site wound infection in lower gastrointestinal surgery. A systematic literature search up to June 2022 was performed and 6026 subjects with lower gastrointestinal surgery at the baseline of the studies; 3090 of them were using the wound protector, and 2936 were using no wound protector. Odds ratio (OR) with 95% confidence intervals (CIs) were calculated to assess the effect of wound protectors in reducing the incidence of surgical site wound infection in lower gastrointestinal surgery using the dichotomous methods with a random or fixed-effect model. The surgical site wound infection was significantly lower with single-ring wound protectors (OR, 0.53; 95% CI, 0.39-0.83, P = .004), and dual-ring wound protectors (OR, 0.44; 95% CI, 0.35-0.56, P < .001) in subjects with lower gastrointestinal surgery compared with no wound protector. The surgical site wound infection was significantly lower with single-ring wound protectors, and dual-ring wound protectors in subjects with lower gastrointestinal surgery compared with no wound protector. The analysis of outcomes should be with caution because of the low sample size of 5 out of 28 studies in the meta-analysis and a low number of studies in certain comparisons.     

Effects of enhanced recovery after surgery nursing program on the surgical site wound infection and postoperative complications in patients of gastric cancer: A meta-analysis

This meta-analysis systematically evaluates the impact of the enhanced recovery after surgery (ERAS) concept on surgical site wound infections and postoperative complications in gastric cancer patients. A comprehensive computerized search was conducted in PubMed, Embase, Google Scholar, Cochrane Library, China National Knowledge Infrastructure and Wanfang databases for randomized controlled trials (RCTs), from database inception to November 2023, exploring the application of the ERAS concept in the perioperative period of gastric cancer surgery. Two researchers independently screened the literature, extracted data, and conducted quality assessments based on inclusion and exclusion criteria. Data analysis was performed using Stata 17.0 software. A total of 24 RCTs involving 2050 gastric cancer patients were included. The analysis revealed a significantly lower incidence of wound infections (OR = 0.23, 95% CI: 0.14–0.40, p < 0.001) and postoperative complications (OR = 0.20, 95% CI: 0.15–0.27, p < 0.001) in the ERAS group compared to the standard care group. This study demonstrates that the application of the ERAS concept during the perioperative period in gastric cancer surgery can effectively reduce the occurrence of wound infections and complications, thereby facilitating postoperative recovery.     

A meta-analysis examined the effect of topical vancomycin application in decreasing sternal wound infections post cardiac surgery

To assess the impact of topical vancomycin (TV) application in decreasing sternal wound infections (SWIs) post cardiac surgery (CS), we lead a meta-analysis. Twenty-three thousand seven hundred and forty five participants had CS at the outset of the investigations, according to a thorough evaluation of the literature done up to November 2022; 8730 of them used TV, while 15 015 were controls. To assess the effectiveness of TV application in lowering SWIs following CS, odds ratios (OR) with 95% confidence intervals (CIs) were computed with dichotomous technique with a fixed- or random-effect model. The TV had significantly lower SWIs post CS (OR, 0.34; 95% CI, 0.20–0.57; P < .001), and deep SWIs post CS (OR, 0.26; 95% CI, 0.11–0.65; P = .004) compared with control as shown in Figures 2 and 3. Yet, there was no significant difference found amongst TV and control in superficial SWIs post CS (OR, 0.30; 95% CI, 0.07–1.30; P = .011). The TV had significantly lower SWIs, and deep SWIs post CS, and no significant difference was found in superficial SWIs post CS compared with control. The low number of included studies in this meta-analysis for superficial SWIs calls for precaution when analysing the outcomes.     

The wound adjuncts effect of closed incision negative pressure wound therapy on stopping groin surgical site wound infection in arterial surgery: A meta-analysis

A meta-analysis study was conducted to assess the influence of the wound adjuncts therapy of closed incision negative pressure wound therapy (ciNPWT) on stopping groin site wound infection (SWSI) in arterial surgery. A comprehensive literature examination till January 2023 was implemented and 2186 linked studies were appraised. The picked studies contained 2133 subjects with groin surgical wounds of arterial surgery in the picked studies' baseline, 1043 of them were using ciNPWT, and 1090 were using standard care. Odds ratio (OR) in addition to 95% confidence intervals (CIs) were used to calculate the consequence of the wound adjuncts therapy of ciNPWT on stopping groin SWSI in arterial surgery by the dichotomous and continuous styles and a fixed or random model. The ciNPWT had a significantly lower SWSI (OR, 0.42; 95% CI, 0.33–0.55, P < .001), superficial SWSI (OR, 0.46; 95% CI, 0.33–0.66, P < .001), and deep SWSI (OR, 0.39; 95% CI, 0.25–0.63, P < .001) compared with the standard care in groin surgical wound of arterial surgery. The ciNPWT had a significantly, lower SWSI, superficial SWSI, and deep SWSI compared with the standard care in groin surgical wounds of arterial surgery. Although precautions should be taken when commerce with the consequences because some of the picked studies for this meta-analysis was with low sample sizes.     

Outcomes of orthopaedic trauma patients undergoing surgery during the peak period of COVID-19 infection at a UK major trauma centre

BackgroundTo review the clinical outcomes of all patients undergoing emergency orthopaedic trauma surgery at a UK major trauma centre during the first 6 weeks of the COVID-19 related lockdown.MethodsA retrospective review was performed of all patients who underwent emergency orthopaedic trauma surgery at a single urban major trauma centre over the first six-week period of national lockdown. Demographics, co-morbidities, injuries, injury severity scores, surgery, COVID-19 status, complications and mortalities were analysed.ResultsA total of 76 patients were included for review who underwent multiple procedures. Significant co-morbidity was present in 72%. The overall COVID-19 infection rate of the study population at any time was 22%. Sub-group analysis indicated 13% had active COVID-19 at the time of surgery. Only 4% of patients developed COVID-19 post surgery with no mortalities in this sub-group. The overall mortality rate was 4%. The overall complication rate was 14%. However mortality and complications rates were higher if the patients had active COVID-19 at surgery, if they were over 70 years and had sustained life-threatening injuries.ConclusionThe overall survival rate for patients undergoing emergency orthopaedic trauma surgery during the COVID-19 peak was 96%. The rate of any complication was more significant in those presenting with active COVID-19 infections who had sustained potentially life threatening injuries and were over 70 years of age. Conversely those without active COVID-19 infection and who lacked significant co-morbidities experienced a lower complication and mortality rate.     

A meta-analysis of the effect of different body mass index on surgical wound infection after colorectal surgery

We conducted a meta-analysis to assess the effect of different body mass index on surgical wound infection after colorectal surgery. A systematic literature search up to November 2022 was performed and 2349 related studies were evaluated. The chosen studies comprised 15 595 colorectal surgery subjects participated in the selected studies' baseline trials; 4390 of them were obese according to the selected body mass index cut-off used to measure obesity in the selected studies, while 11 205 were nonobese. Odds ratio (OR) with 95% confidence intervals (CIs) were calculated to assess the effect of different body mass index on wound infection after colorectal surgery by the dichotomous methods with a random or fixed effect model. The body mass index ≥30 kg/m² resulted in significantly higher surgical wound infection after colorectal surgery (OR, 1.76; 95% CI, 1.46–2.11, P < .001) compared with the body mass index <30 kg/m². The body mass index ≥25 kg/m² resulted in significantly higher surgical wound infection after colorectal surgery (OR, 1.64; 95% CI, 1.40–1.92, P < .001) compared with the body mass index <25 kg/m². The subjects with higher body mass index had a significantly higher surgical wound infection after colorectal surgery compared with the subjects with normal body mass index.     

Impact of negative pressure wound drainage compared with natural wound drainage after thyroid tumour surgery: A meta-analysis

We conducted a meta-analysis to compare the effectiveness of negative pressure wound drainage to that of spontaneous wound drainage after thyroid tumour surgery. A thorough analysis of the literature up to July 2022 revealed that, of the 1234 patients who used surgery for thyroid tumours, 615 used negative pressure wound drainage and 619 used natural wound drainage. To measure the influence of negative pressure wound drainage in comparison to natural wound drainage following thyroid tumour surgery, mean difference (MD) and odds ratio (OR) with 95% confidence intervals (CIs) were measured using the contentious and dichotomous approaches with a random or fixed-effect model. Subjects who used negative pressure wound drainage had significantly higher averages for drained material (OR, 12.52; 95% CI, 6.78-18.26, P = 0.001), shorter drain placement times (MD, −1.06; 95% CI, 1.57 to −0.55, P = .001), lower rates of infection at the surgical site (OR, 0.17; 95% CI, 0.05-0.60, P = .006), higher rates of wound healing (OR, 5.91; 95% CI, 1.56-22.34, P = .009), and lower rate of wound seroma (OR, 0.21; 95% CI, 0.10-0.42, P < .001) in subjects after thyroid tumour surgery in comparison to subjects who used natural wound drainage after thyroid tumour surgery. Those who used negative pressure wound drainage had significantly higher averages of drained material, shorter drain placement times, lower rates of wound infection at the surgical site, higher rates of wound healing, and lower rates of wound seroma. Care must be used when analysing the results because of the small sample size of 7 of the 13 studies included in the meta-analysis and the lack of studies in several comparisons.     

Effect of instant surgery compared with traditional management on paediatric complicated acute appendicitis post-surgery wound: A meta-analysis

A meta-analysis study to assess the influence of instant surgery (IS) compared with conservative therapy (CT) on paediatric complicated acute appendicitis (CAA) post-surgery wounds. A comprehensive literature examination until January 2023 was implemented, and 2098 linked studies were appraised. The picked studies contained 66 674 subjects with paediatric CAA post-surgery wounds in the picked studies' baseline; 64 643 of them were using IS, and 2031 were using CT. The odds ratio (OR) in addition to 95% confidence intervals (CIs) were used to calculate the consequence of the IS compared with the CT on paediatric CAA post-surgery wounds using the dichotomous and continuous styles and a fixed or random model. The IS had a significantly higher wound infection (OR, 4.97; 95% CI, 2.35–10.54, P < .001) with moderate heterogeneity (I² = 57%) compared with the CT in a paediatric CAA post-surgery wound. However, no significant difference was found between IS and CT in total antibiotic duration (MD, −5.34; 95% CI,−12.67 to −1.98, P = .15) with high heterogeneity (I² = 95%) in paediatric CAA post-surgery wounds. The IS had a significantly higher wound infection; however, no significant difference was found in total antibiotic duration compared with the CT in paediatric CAA post-surgery wounds. Although precautions should be taken when commerce with the consequences because most of the studies picked for this meta-analysis had low sample sizes.     

Prognostic factors for chronic post-surgical pain after lung and pleural surgery: a systematic review with meta-analysis,meta-regression and trial sequential analysis

Chronic post-surgical pain is known to be a common complication of thoracic surgery and has been associated with a lower quality of life, increased healthcare utilisation, substantial direct and indirect costs, and increased long-term use of opioids. This systematic review with meta-analysis aimed to identify and summarise the evidence of all prognostic factors for chronic post-surgical pain after lung and pleural surgery. Electronic databases were searched for retrospective and prospective observational studies as well as randomised controlled trials that included patients undergoing lung or pleural surgery and reported on prognostic factors for chronic post-surgical pain. We included 56 studies resulting in 45 identified prognostic factors, of which 16 were pooled with a meta-analysis. Prognostic factors that increased chronic post-surgical pain risk were as follows: higher postoperative pain intensity (day 1, 0–10 score), mean difference (95%CI) 1.29 (0.62–1.95), p < 0.001; pre-operative pain, odds ratio (95%CI) 2.86 (1.94–4.21), p < 0.001; and longer surgery duration (in minutes), mean difference (95%CI) 12.07 (4.99–19.16), p < 0.001. Prognostic factors that decreased chronic post-surgical pain risk were as follows: intercostal nerve block, odds ratio (95%CI) 0.76 (0.61–0.95) p = 0.018 and video-assisted thoracic surgery, 0.54 (0.43–0.66) p < 0.001. Trial sequential analysis was used to adjust for type 1 and type 2 errors of statistical analysis and confirmed adequate power for these prognostic factors. In contrast to other studies, we found that age had no significant effect on chronic post-surgical pain and there was not enough evidence to conclude on sex. Meta-regression did not reveal significant effects of any of the study covariates on the prognostic factors with a significant effect on chronic post-surgical pain. Expressed as grading of recommendations, assessment, development and evaluations criteria, the certainty of evidence was high for pre-operative pain and video-assisted thoracic surgery, moderate for intercostal nerve block and surgery duration and low for postoperative pain intensity. We thus identified actionable factors which can be addressed to attempt to reduce the risk of chronic post-surgical pain after lung surgery.
