The effect of Lavender on pain and healing of episiotomy: A systematic review

Randomized controlled trial of the effectiveness of olive and black seed oil combination on pain intensity and episiotomy wound healing in primiparous women: A study protocol

BACKGROUND

Episiotomy is associated with side effects, such as pain and wound infection. Additionally, discomfort after episiotomy affects the quality of life of both the mother and the baby. Medicinal herbs are one alternative method for the treatment of episiotomy wounds. This study will investigate the effectiveness of the combination of olive and black seed oil on pain intensity and the healing of episiotomy wounds in primiparous women.

METHODS

This randomized clinical trial will be conducted on primiparous women who have had a normal delivery with an episiotomy. There are 3 groups in this study: one group will receive a combination of olive oil and black seed oil, another group will receive olive oil alone, and the use of oils will start 24 hours after delivery. Ten drops will be applied topically 3 times a day for 10 days. The third group (control) will receive only routine care. Data will be collected through a demographic characteristics questionnaire, REEDA (Redness, Edema, Ecchymosis, Discharge, and Approximation) Scale, and Visual Analog Scale. To determine and compare the effects of pharmaceutical interventions on pain intensity and episiotomy wound healing in the groups, an analysis of variance (ANOVA) test with repeated measurements will be used with SPSS version 22.

DISCUSSION

The results of this study will show the effects of a combination of olive and black seed oil, as well as olive oil alone, on pain intensity and episiotomy wound healing in primiparous women. The positive effects observed in this trial with these oils could be valuable for women who have undergone an episiotomy.

Effectiveness of small-angle episiotomy on incisional laceration rate, suturing time, and incisional bleeding in primigravida: A meta-analysis

Objective

To investigate the effect of small-angle lateral perineal incision on postoperative perineal rehabilitation in primiparous women.

Method

The Cochrane Library, PubMed, Embase, CINAHL, CNKI, WanFang, VIP, and the Chinese Biomedical Literature Database were searched for randomized controlled trials (RCTs) on the effect of small-angle episiotomy on postoperative maternal perineal wound rehabilitation in puerpera until April 3, 2022. Two researchers independently performed literature screening, data extraction and evaluation of risk of bias in the included literature, and statistical analysis of the data was performed using RevMan 5.4 and Stata 12.0 software.

Result

A total of 25 RCTs were included, with a total sample of 6,366 cases. Meta-analysis results showed that the use of small-angle episiotomy reduced incisional tearing [OR = 0.32, 95% CI (0.26, 0.39)], shortened incisional suture time [MD = −4.58 min, 95% CI (−6.02, −3.14)] and reduced incisional bleeding [MD = −19.08 mL, 95% CI (−19.53, −18.63)], with statistically significant differences (all p < 0.05). There was no significant difference in the rate of severe laceration between the two groups [OR = 2.32, 95% CI (0.70, 7.70), p > 0.05].

Conclusion

The use of a small-angle episiotomy during vaginal delivery can reduce the incision tear rate without increasing the incidence of severe perineal laceration, while shortening the incisional suturing time and reducing incisional bleeding. It can be used clinically according to birth canal conditions of the maternal, the intrauterine condition of the fetus and maternal needs.

Exploring Iberian Peninsula Lamiaceae as Potential Therapeutic Approaches in Wound Healing

Skin tissue has a crucial role in protecting the human body from external harmful agents, preventing wounds that frequently demand proper healing approaches. The ethnobotanical knowledge of specific regions with further investigation on their medicinal plants has been paramount to create new and effective therapeutical agents, including for dermatological purposes. This review attempts, for the first time, to investigate the traditional applications of Lamiaceae medicinal plants that are already used by local communities in the Iberian Peninsula in wound healing. Henceforward, Iberian ethnobotanical surveys were reviewed, and the information about the traditional wound healing practices of Lamiaceae was comprehensively summarized. Afterwards, the scientific validation of each Lamiaceae species was exhaustively checked. From this, eight out of twenty-nine Lamiaceae medicinal plants were highlighted by their wound-related pharmacological evidence and are in-depth presented in this review. We suggest that future studies should focus on the isolation and identification of the active molecules of these Lamiaceae, followed by robust clinical trials that may confirm the security and effectiveness of such natural-based approaches. This will in turn pave the way for more reliable wound healing treatments.

Natural Herbal Non-Opioid Topical Pain Relievers-Comparison with Traditional Therapy

Pain is the predominant symptom of many clinical diseases and is frequently associated with neurological and musculoskeletal problems. Chronic pain is frequent in the elderly, causing suffering, disability, social isolation, and increased healthcare expenses. Chronic pain medication is often ineffective and has many side effects. Nonsteroidal over-the-counter and prescription drugs are frequently recommended as first-line therapies for pain control; however, long-term safety issues must not be neglected. Herbs and nutritional supplements may be a safer and more effective alternative to nonsteroidal pharmaceuticals for pain management, especially when used long-term. Recently, topical analgesic therapies have gained attention as an innovative approach due to their sufficient efficacy and comparatively fewer systemic side effects and drug-drug interactions. In this paper, we overview the main natural herbal pain relievers, their efficacy and safety, and their potential use as topical agents for pain control. Although herbal-derived medications are not appropriate for providing quick relief for acute pain problems, they could be used as potent alternative remedies in managing chronic persistent pain with minimal side effects.

The effect of lavender on stress in individuals: A systematic review and meta-analysis

BACKGROUND

Lavender is considered as one of the medicinal plants to manage stress. Although many preliminary studies evaluated the effect of lavender on individuals' stress level, to the best of our knowledge, we did not find a study that summarizes the results. Therefore, the present study aimed to estimate the Pooled effect of lavender on the stress level of individuals using systematic review and meta-analysis.

METHOD

A systematic literature review based on PRISMA 2020 was performed on the SID, MagIran, Embase, PubMed, Scopus, Web of Science (WoS) databases, and Google Scholar motor engine using related MeSH/Emtree and ‎Free Text words,‎ including "Lavender*", "Lavandula*", "Stress*", "Stress Disorders, Traumatic", and "Stress, Psychological" with no time limitation until August 2021: We also searched two Iranain free local resourses including MagIran https://www.magiran.com and Scientific Information Database (SID) https://www.sid.ir. The quality assessment of studies was performed using JBI checklist. Heterogeneity among studies was quantified using I² index and Random Effects model was used to combine the data and perform the meta-analysis.

RESULTS

In the initial search, 1520 articles were found. After excluding the irrelevant studies, finally, 21 articles with a sample size of 791 in the intervention group and 804 in the control group were included in the meta-analysis. As a result of combining the studies, stress score after using lavender in the intervention group showed a significant decrease of 0.63 ± 0.13 (95% CI) more than that in the control group (P < 0.001). The results of subgroup analysis demonstrated that the highest standardized mean difference (SMD) before and after the intervention in the intervention group compared to the control group was related to L. angustifolia species with 0.73 ± 0.22, student groups with 2.27 ± 1.34, and diagnostic tool of Perceived Stress Scale (PSS) with 0.82 ± 0.42, indicating that the difference between the groups was statistically significant (P < 0.001).

CONCLUSION

The pooled estimation of this systematic reiew and meta-analysis revealed that lavender significantly reduces individuals' stress. Therefore, it seems that the use of lavender can be considered as a part of a stress management programs, especially in student groups.

Effect of early skin-to-skin contact after vaginal delivery on pain during perineal wound suturing: A randomized controlled trial

AIM

To evaluate whether early skin-to-skin contact at the end of the second stage of labor could relieve perineal wound suture pain.

METHODS

From March 2020 to November 2020, a total of 241 parturients with full-term single fetuses delivered through the vagina and who underwent episiotomy suture (n = 120) or perineal laceration repair (n = 121) in our hospital were included in the study. Parturients were categorized according to whether they received episiotomy suture or perineal laceration repair. They were randomized into an early skin contact group and a traditional neonatal care group. The primary outcome was pain, which was quantified by the Numerical Rating Scale, Visual Analog Scale, Verbal Rating Scale, Faces Pain Scale-Revised. The secondary outcomes were healing of the perineal wound, the maternal cooperation rate and operation time. The confounding factors of severe pain were analyzed.

RESULTS

Early skin-to-skin contact alleviated the pain of perineal laceration repair and episiotomy suture, shortened the operation time of episiotomy suture and improved the cooperation rate of parturients receiving suture. It had no effect on perineal wound healing, operation time, or the cooperation rate of perineal laceration repair. In addition to the operation and early skin contact, the occurrence of high-grade pain was also associated with prepregnancy body mass index, group B streptococcus (GBS) positive, and academic degree.

CONCLUSION

Early skin-to-skin contact at the end of the second stage of labor can alleviate pain and improve the delivery experience of vaginal delivery.

Chemical and Biochemical Characterization of Essential Oils and Their Corresponding Hydrolats from Six Species of the Lamiaceae Family

Many plants belonging to the Lamiaceae family are rich in essential oils (EOs) which are intensively used for aromatherapy, food and beverage flavoring, alternative medicine, cosmetics, and perfumery. Aerial parts of Thymus vulgaris L., Thymus pannonicus All., Lavandula angustifolia L., Lavandula x intermedia, Origanum vulgare L., and Origanum vulgare var. aureum L. were subjected to hydrodistillation, and both resulting fractions were analyzed. The purpose of this study was to determine the chemical composition, antioxidant activity, and total phenolic content of six essential oils and their corresponding hydrolats (HDs) through GC-MS and spectrophotometric analyses. Overall, 161 compounds were identified, some found exclusively in essential oils and others in hydrolats, making them individual products with specific end purposes. The total phenolic content was the highest for the Thymus vulgaris L. EOs (3022 ± mg GAE L-1), because of its high phenolic oxygenated monoterpenes content (thymol and carvacrol) and the smallest for the Lavandula angustifolia L. EOs (258.31 ± 44.29 mg GAE L-1), while hydrolats varied from 183.85 ± 0.22 mg GAE L-1 for Thymus vulgaris L. HD and 7.73 mg GAE L-1 for Thymus pannonicus All. HD. Significant antioxidant effects determined through DPPH• and ABTS•+ assays were also observed in samples with higher hydrophilic compounds. The highest antioxidant activity was determined for Thymus vulgaris L. EO and its corresponding HD. Although EOs are the principal traded economic product, HDs represent a valuable by-product that could still present intense antiseptic activities, similar to their corresponding EOs (thyme and oregano), or have multiple aromatherapy, cosmetics, and household applications (lavender and lavandin).

Effectiveness of lavender inhalation aromatherapy on pain level and vital signs in children with burns: a randomized controlled trial

BACKGROUND

Burns are a source of pain, which cannot be fully treated with medications.

OBJECTIVES

This study aims is to test the effectiveness of lavender oil inhalation aromatherapy applied before dressing change on vital signs and pain levels of children with burns.

DESIGN

This randomized controlled study was held between May 2018 and May 2019. A total of 108 children who met the inclusion criteria were studied in three groups: Lavender-15 Group inhaled lavender oil for 15 min before dressing (n:36), Lavender-60 Group inhaled lavender oil for 60 min before dressing (n:36), and Control Group inhaled jojoba (placebo) oil for 15 min before dressing (n:36). Baseline pain levels and vital signs of the children were measured before inhalation. Pain levels and vital signs of the children were re-measured at the 1st and 30th minutes after dressing.

RESULTS

There was no significant difference between the groups in terms of pain levels (p = 0.750) and vital signs before dressing. In post-dressing measurements, the number of respiration (after 1 min p = 0.000, after 30 min p = 0.000), heart rate (after 1 min p = 0.000, after 30 min p = 0.000), mean arterial blood pressure (after 1 min p = 0.010, after 30 min p = 0.000) and pain levels (after 1 min p = 0.000, after 30 min p = 0.000) were lower in the Lavender groups compared to the placebo group.

DISCUSSION

The result of this research reveals that inhalation aromatherapy which applied before dressing in children with burns affects the reduction of pain levels and stabilization of vital signs.

The effect of the Verbascum Thapsus on episiotomy wound healing in nulliparous women: a randomized controlled trial

Background

The pain and discomfort caused by episiotomy affect the quality of life of the mothers, so rapid and complete repair of the episiotomy is very important. Due to the effective ingredients of Verbascum Thapsus, it has been used since ancient times to treat wounds. Therefore, this study aimed to evaluate the effect of Verbascum Thapsus on episiotomy wound healing.

Methods

The study was designed as a randomized, double-blind, controlled clinical trial. Ninety-three primiparous women who were referred to Fatemeh Zahra Hospital in Saveh in 2015 were randomly divided into two groups of intervention (Verbascum Thapsus) and control (placebo). Both groups covered the episiotomy wound twice a day for 10 days with 2 cm of prescribed creams. Wound healing was assessed using the REEDA scale before the intervention and on days 1,3 and 10 after the intervention.

Results

Before the intervention, there was no statistically significant difference in terms of demographic characteristics, obstetrics, and REEDA scores between the two groups (p < 0.05). The mean scores of REEDA on days 1 and 3 in the intervention group were better than the control group but were not statistically significant. However, on the tenth day after the intervention, the mean scores of REEDA were significantly better in the Verbascum group than the placebo (p = 0.01).

Conclusions

According to the results of this study, it seems that Verbascum Thapsus is effective in repairing episiotomy wounds. The researchers hope that the results of this study can provide clinical evidence for the use of this herbal medicine in the wound healing process.

Trial registration

This study was registered in the Iranian Registry of Clinical Trials (IRCT) with the code “IRCT201404073106N15” on 02/12/2015.

The effect of music and skin contact with the newborn on pain and anxiety during episiotomy repair in primiparous women: A double-blind randomized controlled study

OBJECTIVE

To show that music medicine and skin contact with the newborns can reduce pain and anxiety during episiotomy repair.

DESIGN

Double-blind randomized controlled trial SETTING: The study was conducted between April and July 2020 at the private Medipol Nisa Hospital.

PARTICIPANTS

A total of 150 primiparous pregnant women over 20 years of age who underwent vaginal delivery with episiotomy INTERVENTIONS: Participants were randomized into the music medicine, skin contact with the newborn, and control groups (with no treatment). After episiotomy repair (with the designated treatment or no treatment), the State Trait Anxiety Inventory and Visual Analog Scale were used to assess anxiety and pain, respectively.

MAIN OUTCOME MEASURES

Pain and anxiety experienced after episiotomy repair in the treatment and control groups.

RESULTS

Women in both treatment groups (music medicine and skin-to-skin contact) had significantly lower anxiety and pain levels than those in the control group. In particular, music medicine significantly reduced pain in comparison to skin contact with the newborn (VAS 2 3.92 ± 1.46 vs. 5.42 ± 1.73, respectively, VAS 3 2.64 ± 1.63 vs. 5.14 ± 1.77, respectively, VAS 4 1.38 ± 1.46 vs. 4.14 ± 2.04, respectively, p < 0.05). Thus, music medicine is more effective than skin-to-skin contact in reducing the pain experienced during episiotomy repair, but both treatments were equally effective in reducing anxiety (35.30 ± 6.47 vs. 36.82 ± 9.71 vs. 49.22 ± 16.95, respectively, p < 0.05).

CONCLUSION

Both of these nonpharmacological treatments can be used along with analgesics and anxiolytics for the treatment of pain and anxiety during episiotomy repair.
