Non-pharmacological labor pain relive methods: utilization and associated factors among midwives and maternity nurses in Najran, Saudi Arabia.

BACKGROUND: Traditionally, pharmacological pain relief methods have been the most acceptable option for controlling labor pain, accompanied by numerous adverse consequences. Non-pharmacological labor pain relive methods can reduce labor pain while maintaining an effective and satisfying delivery experience and delaying the use of pharmacological methods. This study explores the utilization of non-pharmacological labor pain relive methods and its associated factors among midwives and maternity nurses. METHODS: A cross-sectional research was conducted in Maternal and Children Hospital/Najran, Saudi Arabia, from April to May 2023 and incorporated a convenience sample of 164 midwives and maternity nurses. The data was collected using a self-reported questionnaire composed of five sections; basic data, facility-related factors, non-pharmacological labor pain relive utilization and attitude scales, and knowledge quiz. A logistic regression was used to determine the associated factors with non-pharmacological labor pain relive utilization. RESULTS: The results revealed that 68.3% of participants utilized non-pharmacological labor pain relive methods. The midwives and maternity nurses helped the parturient to tolerate labor pain by applying the non-pharmacological labor pain relive methods, including; positioning (55.5%), breathing exercises (53.7%), comfortable and relaxing environment (52.4%), therapeutic communication (47%), positive reinforcement (40.9%), relaxation (40.2%), and therapeutic touch (31%). In addition, working unit, providers-patient ratio, working hours, non-pharmacological labor pain relive training, years of experience, and non-pharmacological labor pain relive attitude were significant determinants of non-pharmacological labor pain relive utilization (P < 0.05). CONCLUSIONS: High non-pharmacological labor pain relive utilization was significantly associated with nurses' older age and higher education, working in the delivery room, lower nurse-patient ratio, lower working hours, in-services training, increased years of experience, and positive attitude. The study sheds light on the importance of handling the pre-mentioned factors to enhance non-pharmacological labor pain relive utilization.

The impact of l-arginine supplementation on the enteral phase of experimental Trichinella spiralis infection in treated and untreated mice.

The role of nitric oxide (NO) in the immunopathological response during Trichinella spiralis (T. spiralis) infection remains controversial. The amino acid, l-arginine is a NO precursor commonly used by athletes and bodybuilders as a protein supplement. As to our knowledge, there are no published studies which have tested the effect of l-arginine on the intestinal phase of experimental trichinellosis. The present work aims to investigate the effect of l-arginine on the enteral phase of experimental T. spiralis infection in albendazole-treated and untreated mice. Forty BALB/C mice infected orally with T. spiralis larvae were divided into 4 groups as follows: Group A were infected and untreated (control) mice, Group B received albendazole alone, Group C received l-arginine alone, and Group D received both l-arginine and albendazole. Compared to the control group, l-arginine supplementation showed; a significant increase in the intestinal adult worm burden, a significantly high inducible NO synthase (iNOS) expression, elevated immune markers; tumor necrosis factor-α (TNF-α) and interferon-γ (IFN-γ), and enhanced apoptosis. Albendazole treated-group had a significant reduction in the adult worm number (90.9%), while combined albendazole-arginine regimen showed a lower percentage of worm reduction (72.7%). During the enteral phase of T. spiralis infection, l-arginine supplementation should be taken cautiously, as it may modulate the proinflammatory immune response and subsequently affect the outcome of the infection and/or treatment.
