Suture type used for perineal injury repair and sexual function: a randomised controlled trial.

ABSTRACT: The type of suture used to repair perineal injury may be associated with this healing process and subsequent sexual function. This study aims to assess whether the suture technique used (continuous or interrupted) has an impact on a woman's sexual function following childbirth. A single-blind randomised clinical trial was conducted with primiparous women who had experienced a perineal injury during childbirth. A computer-generated random number table was applied to allocate women to each group. Data were collected on sociodemographic variables, variables associated with childbirth, and outcomes during the 3 months after childbirth. Mean difference was used to assess the influence of the suture type on outcomes. Multivariate analyses were carried out to adjust for unbalanced variables after randomisation. Seventy women participated in the intervention group (continuous suture) and 64 women in the control group (interrupted suture). The women in the intervention group scored high for sexual desire, adjusted mean difference (aMD)?=?1.8, 95% CI?=?1.1-2.6 (p?

Project description:BackgroundThe technique used in the repair of a perineal injury resulting from childbirth could avoid discomfort and morbidity during the postpartum period. Recent studies show inconsistent results and support the need for new research with the inclusion of new health parameters not yet studied. Therefore, this study aims to evaluate if the suture technique (continuous or interrupted) has an effect on pain and other postpartum problems, incidence of incontinence (urinary and/or fecal), and the restart of sexual relations.MethodsA single-blind randomized clinical trial was conducted in five hospitals in south-east Spain. The participants were primiparous women who had experienced a perineal injury during delivery (second-degree tear or episiotomy). Data was collected on sociodemographic variables, variables associated with pregnancy, labor and delivery, and the postpartum period, and outcomes during the 3 months after delivery: pain, incontinence, and restart of sexual relations. Odds ratios (OR) were calculated by binary logistic regression to assess the influence of the suture type on binary outcomes and t-test used for comparing continuous outcomes. Multivariate analyses (using logistic regression -adjusted (aOR)- and analysis of covariance) were carried out to adjust for unbalanced variables after randomization.ResultsA total of 70 women were included in the intervention group (continuous suture) and 64 in the reference group (interrupted sutures). A negative association was observed (aOR = 0.39; 95% CI = 0.18-0.86) between a continuous suture and the need for analgesia at 24 h postpartum. Pain experienced by the women at 24 h postpartum was assessed as 4.4 ± 0.3 compared with a score of 3.4 ± 0.3 in the group with continuous sutures (p = 0.011). At 15 days postpartum, women in the intervention group experienced less pain (aOR = 0.38; 95% CI = 0.18-0.80) (p = 0.019). Urinary sphincter incontinence was also evaluated at 15 days, with 4.3% (n = 3) of the women in the intervention group presenting with urinary incontinence compared with 18.8% (n = 12) in the control group (aOR = 0.11; 95% CI = 0.03-0.47) (P = 0.003).ConclusionsThe women who had a continuous suture repair showed lower levels of pain from delivery to 3 months after delivery and had a lower incidence of urinary incontinence at 15 days postpartum.Trial registrationClinicalTrials.gov NCT03825211 posted January 31, 2019 (retrospectively registered).

Project description:PurposeTo assess the mechanical properties, tendon resistance to suture cutout, and knot size of a broad variety of high-strength sutures and tapes available for arthroscopic rotator cuff repair.MethodsNine different types of high-strength sutures and tapes for arthroscopic rotator cuff repair were studied: 6 were tapes (FiberTape, Hi-Fi Tape, Permatape, SutureTape, UltraTape, and XBraid TT), and 3 were sutures (Dynacord, FiberWire, and Ultrabraid). First, mechanical tensile testing of suture loops (n = 6) was performed. Second, the suture material was passed through an intact human cadaveric rotator cuff tendon (supraspinatus or infraspinatus), and cyclic as well as load-to-failure testing was performed, 8 times for each suture or tape. Statistical analysis of groups (tapes vs sutures) and between each suture and each tape was performed.ResultsMaterial testing revealed significant differences with superior mechanical properties of tapes compared with sutures regarding load for 3 mm of displacement (201 N vs 84 N, P < .0001), displacement at 200 N (3.6 mm vs 6.6 mm, P < .0001), stiffness (46 N/mm vs 25 N/mm, P < .0001), and ultimate load to failure (509 N vs 288 N, P < .0001). FiberTape showed the highest ultimate load to failure (805.5 ± 36.1 N), the highest load necessary for 3 mm of displacement (376.2 ± 19.1 N), and the lowest displacement at a 200-N load (2 ± 0.1 mm). Permatape had the highest stiffness (58.5 ± 5.3 N/mm). FiberTape had the highest knot height (9.5 ± 1.3 mm) and knot width (3.8 ± 0.7 mm) of a suture loop with 7 square knots. The typical failure mode in the cadaveric study part was tendon cut through.ConclusionsBiomechanical in vitro testing showed that high-strength suture tapes compared with regular high-strength sutures have significantly better mechanical properties in both dry-laboratory testing and human cadaveric rotator cuff tendon pullout testing. FiberTape outperformed the other tapes and the sutures used in this analysis. Nonetheless, differences in tendon testing appeared to be less substantial than in dry-laboratory testing, and FiberTape had the highest knot height and width.Clinical relevanceFiberTape revealed the most favorable biomechanical performance in dry-laboratory and rotator cuff tendon testing. It may provide the best repair strength in vivo; however, it also has the largest knot size.

Project description:OBJECTIVE:Sexuality is an important aspect of human identity and contributes significantly to the quality of life in women as well as in men. Impairment in sexual health after vaginal delivery is a major concern for many women. We aimed to examine the association between degree of perineal tear and sexual function 12 months postpartum. DESIGN:A prospective cohort study SETTING: Four Danish hospitals between July 2015 and January 2019 PARTICIPANTS: A total of 554 primiparous women: 191 with no/labia/first-degree tears, 189 with second-degree tears and 174 with third-degree/fourth-degree tears. Baseline data were obtained 2 weeks postpartum by a questionnaire and a clinical examination. Sexual function was evaluated 12 months postpartum by an electronic questionnaire (Pelvic Organ Prolapse/Urinary Incontinence Sexual Function Questionnaire (PISQ-12)) and a clinical examination. PRIMARY OUTCOME MEASURES:Total PISQ-12 score and dyspareunia RESULTS: Episiotomy was performed in 54 cases and 95 women had an operative vaginal delivery. The proportion of women with dyspareunia was 25%, 38% and 53% of women with no/labia/first-degree, second-degree or third-degree/fourth-degree tears, respectively.Compared with women with no/labia/first-degree tears, women with second-degree or third-degree/fourth-degree tears had a higher risk of dyspareunia (adjusted relative risk (aRR) 2.05; 95%?CI 1.51 to 2.78 and aRR 2.09; 95%?CI 1.55 to 2.81, respectively). Women with third-degree/fourth-degree tears had a higher mean PISQ-12 score (12.2) than women with no/labia/first-degree tears (10.4). CONCLUSIONS:Impairment of sexual health is common among primiparous women after vaginal delivery. At 12 months postpartum, more than half of the women with a third-degree/fourth-degree tear experienced dyspareunia. Women delivering with no/labia/first-degree tears reported the best outcomes overall. Thus, it is important to minimise the extent of perineal trauma and to counsel about sexuality during and after pregnancy.
