The effect of different types of abdominal binders on intra-abdominal pressure

Comparative Efficacy of Abdominal Exercises and Abdominal Binding on Diastasis Recti Abdominis Reduction in Postpartum Women: A Systematic Review and Meta-Analysis of Randomized Controlled Trials

BACKGROUND AND PURPOSE

Diastasis Recti Abdominis (DRA) is a separation of the rectus abdominis muscles which often results from pregnancy. This meta-analysis aims to identify the most effective non-surgical treatment to reduce post-partum DRA.

METHODS

A comprehensive search was performed on electronic databases including PubMed, Cochrane, and Embase databases for RCTs involving abdominal or pelvic muscle exercises, and abdominal binding for DRA Reduction. Primary outcomes included inter-recti distance (IRD) Resolution, Oswestry Disability Index (ODI) score, and Pelvic Floor Disability Index (PFDI) score. ROB 2.0 tool was used for the risk of bias assessment of RCTs. Meta-analysis was performed using Review Manager version 5.4. Sensitivity analysis was conducted to determine the influence of studies on the overall results. Meta regression was performed using R version 4.4 to identify the sources of heterogeneity.

RESULTS

Thirteen RCTs were included in the analysis. Abdominal exercise significantly reduced IRD below the umbilicus compared with abdominal binding (Mean difference [MD] = -0.31, 95% CI: -0.53 to -0.10, p = 0.004) but was ineffective for IRD resolution ≥ 2 cm above the umbilicus (MD = 0.22, 95% CI: -1.43 to 1.88, p = 0.79). Compared with no intervention, abdominal exercise significantly reduced IRD below the umbilicus (MD = -0.31, 95% CI: -0.53 to -0.10, p = 0.004) but was ineffective in IRD resolution ≥ 2 cm above the umbilicus (MD = 0.11, 95% CI: -0.38 to 0.59, p = 0.67). No significant reduction was found in the ODI score (MD = -5.57, 95% CI: -19.31 to 8.17, p = 0.43) and PFDI score (MD = -12.99, 95% CI: -43.49 to 17.51, p = 0.04).

DISCUSSION

Abdominal exercises reduce IRD below the umbilicus more effectively than binding and no intervention, but their effectiveness above the umbilicus is unclear. ODI and PFDI showed no significant improvement. Further research with standardized criteria and diverse population is needed to clarify the efficacy of these treatments for diastasis recti.

Combined effect of intermittent hemostasis and a modified external hemorrhage control device in a lethal swine model

Background

Non-compressible torso hemorrhage (NCTH) presents the ultimate challenge in pre-hospital care. While external hemorrhage control devices (EHCDs) such as the Abdominal Aortic and Junctional Tourniquet (AAJT) and SAM Junctional Tourniquet (SJT) have been invented, the current design and application strategy requires further improvement. Therefore, researchers devised a novel apparatus named Modified EHCD (M-EHCD) and implemented intermittent hemostasis (IH) as a preventive measure against ischemia-reperfusion injury. The objective of this study was to ascertain the combined effect of M-EHCD and IH on the hemostatic effect of NCTH.

Methods

Eighteen swine were randomized to M-EHCD, AAJT or SJT. The NCTH model was established by inducing Class Ⅲ hemorrhagic shock and performing a hemi-transection of common femoral artery (CFA). EHCDs were rapidly fastened since the onset of free bleeding (T0min). The IH strategy was implemented by fully releasing M-EHCD at T40min, T70min and T100min, respectively, whereas AAJT and SJT maintained continuous hemostasis (CH) until T120min. All groups underwent CFA bridging at T110min, and EHCDs were removed at T120min. Reperfusion lasted for 60 min, after which euthanasia was performed. Hemodynamics, intra-vesical pressure (IVP), and blood samples were collected periodically. Histological examinations were also conducted.

Results

M-EHCD demonstrated the fastest application time (M-EHCD: 26.38 ± 6.32s vs. SJT: 30.84 ± 5.62s vs. AAJT: 54.28 ± 5.45s, P < 0.001) and reduced free blood loss (M-EHCD: 17.77 ± 9.85g vs. SJT: 51.80 ± 33.70g vs. AAJT: 115.20 ± 61.36g, P = 0.011) compared to SJT and AAJT. M-EHCD exhibited inhibitory effects on heart rate (M-EHCD: 91.83 ± 31.61bpm vs. AAJT: 129.00 ± 32.32bpm vs. SJT: 135.17 ± 21.24bpm, P = 0.041) and shock index. The device's external pressure was lowest in M-EHCD and highest in SJT (P = 0.001). The resultant increase in IVP were still the lowest in M-EHCD (M-EHCD: -0.07 ± 0.45 mmHg vs. AAJT: 27.04 ± 5.03 mmHg vs. SJT: 5.58 ± 2.55 mmHg, P < 0.001). Furthermore, M-EHCD caused the least colonic injury (M-EHCD: 1.17 ± 0.41 vs. AAJT: 2.17 ± 0.41 vs. SJT: 2.17 ± 0.41, P = 0.001). The removal of M-EHCD showed the slightest impact on pH (P < 0.001), while AAJT group was more susceptible to the lethal triad based on the arterial lactate and thrombelastogram results.

Conclusions

M-EHCD + IH protected the organs and reduced the risk of the lethal triad by decreasing disruptions to IVP, hemodynamics, acid-base equilibrium and coagulation. M-EHCD + IH was superior to the hemostatic safety and efficacy of AAJT/SJT + CH.

Effect of abdominal binder on shoulder pain after laparoscopic gynecologic surgery: A randomized, controlled trial

BACKGROUND

To evaluate the impact of abdominal binder (AB) use on postoperative shoulder pain in patients recovering from laparoscopic gynecologic surgery.

METHODS

This was a prospective randomized study conducted in a tertiary teaching hospital. Overall, 144 patients underwent laparoscopic gynecologic surgery. The postoperative use of an AB for 24 hours was added to the pulmonary recruitment maneuver.

RESULTS

Of 144 consenting patients, 72 patients each were allocated to the AB and control groups, respectively, and 14 patients were excluded. Finally, 130 patients were analyzed, with 68 in the AB group and 62 in the control group. There was no difference in the incidence of postoperative shoulder pain between the 2 groups (55.9% vs 56.5%, P = 1.000). The severity of the worst shoulder pain, measured using a numerical rating scale, did not differ between the 2 groups (Median [interquartile range] 2 [0-5] vs 2 [0-5]; P = .865). The severity of surgical site pain, pain and nausea medications, and the ambulation time were not different in the 2 groups.

CONCLUSION

The use of an AB was not beneficial for postoperative shoulder pain following laparoscopic gynecologic surgery. Surgical site pain, ambulation time, and postoperative nausea and vomiting were not improved with the use of an AB.

The effect of Tubigrip and a rigid belt on rectus abdominus diastasis immediately postpartum: A randomised clinical trial

BACKGROUND

Rectus abdominis (RA) diastasis is a risk factor for abdominal muscle dysfunction and reduced quality of life postpartum. It is thought that supplementary abdominal supports might reduce the diastasis. However, there is limited research assessing the efficacy of abdominal supports/binding.

OBJECTIVE

To determine the effects of Tubigrip and a rigid abdominal belt in reducing RA diastasis in the first eight weeks postpartum.

DESIGN

Randomised clinical trial.

METHODS

62 women undertook ultrasound imaging to measure their RA diastasis prior to and after an eight week intervention wearing either Tubigrip or a rigid abdominal belt. Data analyses involved repeated measures ANOVA and correlational methods.

RESULTS

The RA diastasis reduced by 46% from a mean 4.6 cm-2.5 cm over the eight week intervention period with no significant difference (p > 0.05) across groups. Women wore the Tubigrip for a significantly (p < 0.05) longer number of hours (Median: 278) compared to those in the belt group (Median: 81 h). The length of time that women wore Tubigrip or the belt was not associated with the percentage reduction in the RA diastasis (p > 0.05). There was no significant difference in the diastasis across vaginal and Caesarean section deliveries at baseline. There was a significant difference (p < 0.05) in the percent reduction of the RA diastasis across deliveries post-intervention (vaginal delivery mean: 48% vs C-section: 40%).

CONCLUSION

There was no difference across groups post-intervention in the RA diastasis, and it is questionable whether either support improves upon that associated with natural healing alone.

The Value of Ultrasonic Elastographic Parameters in the Evaluation of Chronic Hepatitis B Liver Fibrosis

Chronic hepatitis B is one of the common chronic infectious diseases in China, which seriously endangers people’s health. Liver fibrosis is a common pathological process of chronic hepatitis B. The routine diagnosis and prediction of the degree of liver fibrosis are of great value and significance to the judgment of liver disease, clinical treatment, and the corresponding late evaluation. However, the traditional detection and treatment methods are often invasive, and the corresponding diagnosis and treatment costs are very high, which makes it difficult for the corresponding patients in clinical and practical applications to accept, and the corresponding liver tissue samples are relatively limited in technology. In this paper, based on ultrasound elastography technology, it will give full play to its advantages of real-time, non-invasive, and repeatable detection, and realize an effective method for non-invasive diagnosis of liver fibrosis. In the practical application, this paper mainly focuses on the study and analysis of the patients with hepatitis B liver fibrosis using the RTE ultrasonic elastic imaging technology. Following this, 120 patients with chronic hepatitis B were selected for the experiment, and a non-invasive diagnostic model of ultrasonic elastic imaging based on a support vector machine was proposed. The experimental results showed that the diagnostic model proposed in this paper improves the diagnostic accuracy by 5% compared with the traditional diagnostic technology, while the corresponding specificity, positive predictive value, and diagnostic advantage are improved. Therefore, as a whole, the ultrasound elastic imaging model proposed in this paper could realize the efficient diagnosis of hepatitis B liver fibrosis and is conducive to the clinical management.

The efficacy of abdominal binders in reducing postoperative pain and distress after cesarean delivery: A meta-analysis of randomized controlled trials

OBJECTIVE

To evaluate the efficacy of abdominal binders in reducing postoperative pain, patient distress and surgical postoperative sequelae after cesarean delivery (CD).

METHODS

A comprehensive search in electronic databases (MEDLINE, EMBASE, and Cochrane Central) was performed up to February 2021. Selection criteria included randomized clinical trials investigating the application or not of abdominal binder after CD. The primary outcome was postoperative pain, measured using the visual analog scale (VAS) pain score. Secondary outcomes were divided into short- and long-term postoperative outcomes, including patient distress, need for additional pain medications, time to mobilization, return to normal daily activities, surgical site infection, fascial dehiscence or incisional hernia, and rectus abdominis diastasis. The summary measures were reported as mean difference with 95 % confidence intervals (CI) using the random effects model of DerSimonian and Laird. An I² (Higgins I²) value of greater than 0% was used to identify heterogeneity.

RESULTS

Four RCTs involving 601 women were included for meta-analysis: 310 (51.6 %) were randomized to the abdominal binder and 291 (48.4 %) to no abdominal binder group. There was no statistically significant difference between the two groups for VAS score either at 24 h (MD -0.97, 95 % CI -2.23 to 0.30; p = 0.13) and at 48 h (MD -0.30, 95 % CI -0.71 to 0.11; p = 0.15). Conversely, there was a significant reduction in postoperative distress (SDS) both at 24 h (MD -2.23, 95 % CI -3.77 to -0.70; p = 0.004) and 48 h (MD -2.37, 95 % CI -3.86 to -0.87; p = 0.002).

CONCLUSION

The present meta-analysis shows that the use of abdominal binders after CD significantly reduces patient distress.

A New Device for Measuring Abdominal Wall Tension and Its Value in Screening Abdominal Infection

OBJECTIVE

This study is the largest clinical study of noninvasive Abdominal wall tension (AWT) measurement with a tensiometer to date. It also initially applies a polynomial regression equation to analyze the correlation between AWT measurement and intravesical pressure (IVP) measurement and remarkably finds interesting changes between different IVP intervals and AWT.

METHODS

Critically ill patients who were treated in the intensive care unit (ICU) of Daping Hospital, Army Medical University, from August 30, 2018, to June 30, 2020, and met the inclusion criteria were prospectively included in this study. The patients were divided into an intra-abdominal hypertension group and a non-intra-abdominal hypertension group and an abdominal infection group and no abdominal infection group. AWT and IVP were measured at 9 points on the abdominal wall on the first day after admission to the ICU. The correlations between AWTs and IVP were analyzed, and the role of AWT in the diagnosis of complications of abdominal infection and the prediction of adverse prognosis were analyzed.

RESULTS

A total of 127 patients were included. The average AWT and IVP were 2.77±0.38 N/mm and 12.31±7.01 mmHg, respectively, on the first day of admission. There was a positive correlation between AWT and IVP (correlation coefficient r = 0.706, p < 0.05). The polynomial regression model was AWT= -1.616×10-3 IVP2 +8.323×10-2 IVP+2.094. The cutoff value of the sensitivity and specificity of AWT for the diagnosis of abdominal infection was 2.57 N/mm. Furthermore, AWT = 2.57 N/mm had the best diagnostic efficiency, which was better than that of IAH and lactate.

CONCLUSION

There was a correlation between AWT and IVP. AWT measurement was helpful in the diagnosis of IAH and abdominal infection complications and can therefore serve as a new method for the clinical diagnosis of IVP and abdominal infection.

The impact of exercise therapy and abdominal binding in the management of diastasis recti abdominis in the early post-partum period: a pilot randomized controlled trial

Purpose: To explore the feasibility of two physiotherapy interventions for the management of diastasis recti abdominis (DrA): abdominal binding and targeting trunk exercises.Methods: A pilot randomized controlled trial (RCT) design was used to compare the effectiveness of exercise therapy and/or abdominal binding to no intervention on thirty-two primiparous women who presented with DrA in the early post-partum period. Feasibility was determined based on study recruitment, compliance, and attrition rates as well as through computation of treatment effect sizes associated with each intervention compared to no intervention. Outcomes included inter-rectus distance measured using ultrasound, body image, pain, urogynecological symptoms, and function measured using questionnaires, and trunk flexion strength and endurance measured using clinical tests.Results: The recruitment rate was 3 participants/month. Intervention adherence rates were >50% and the attrition rate was 16%. After 6 months, positive effects (Cohen's d (d) = 0.2-0.5) on body image were observed in both the abdominal binding alone and combination therapy groups. A positive effect on trunk flexion strength (d = 0.7) was observed in the combination therapy group.Conclusion: The effect sizes suggest that physiotherapy interventions can positively impact body image and trunk flexion strength. While a clinical trial investigating these interventions is feasible, further preliminary investigation is recommended.

Use of Abdominal Binders after a Major Abdominal Surgery: A Randomized Controlled Trial

Objective

To compare the effect of abdominal binder versus no binder after major abdominal surgery and cesarean section on various post-operative recovery parameters.

Materials and methods

This is a randomized controlled trial conducted at the Department of General Surgery and Obstetrics, Civil Hospital, Karachi, Pakistan. All those patients aged ≥18 years having abdominal surgery including elective and emergency abdominal surgery and cesarean sections with American Society of Anesthesiologists Class I-III were included in the study. Randomization was done using the sealed envelope method by the principal investigator. The intervention group wore an abdominal binder postoperatively while the control group did not use it. Mobilization and the pain status of both groups were evaluated on the first, fourth, and seventh days after surgery.

Results

Primary outcome variables were mobility, assessed via 6-minute walk test (6MWT) and postoperative pain, evaluated via visual analogue scale. There was no statistically significant difference in the 6MWT distance before (p = 0.278) and on postoperative day one of the surgery (p = 0.0762). However, the difference was significant on fourth (p < 0.001) and seventh day (p value < 0.001). With regards to the pain status, patients in the binder group reported significantly less postoperative pain on first, fourth, and seventh (p value < 0.001) day compared to the non-binder group.

Conclusion

The use of abdominal binder postoperatively significantly reduced pain and improved mobility in both obstetric and surgery patients.
