Comparison the effect of valerian and gabapentin on RLS and sleep quality in hemodialysis patients: A randomized clinical trial

INTRODUCTION

This study aimed to compare the effect of valerian and gabapentin on restless legs syndrome (RLS) and sleep quality in HD patients.

METHODS

In this cross over clinical trial study, 40 HD patients allocated into a valerian and gabapentin group. In the first phase of the study, Group A received valerian and Group B received gabapentin 1 h before bedtime for 1 month. In the second phase, the two groups' treatment regimen was swapped. After a 1-month washout period, the same process was repeated on the crossover groups.

RESULTS

After the first phase, the mean score of RLS was lower in the gabapentin group. But there was no statistically significant difference between the two groups in terms of sleep quality score before and after the first and second interventions.

CONCLUSION

Gabapentin is more effective than valerian in improving RLS, but both are equally effective in improving sleep quality.

Identification of strategies for collaboration of medical librarians with family physicians in advancing the goals of the family physician program based on experts’ viewpoints

Objectives: The present study was carried out with the aim of identifying ways of collaboration of medical librarians with family physicians in advancing the goals of the family physician program based on the views of experts. Methods: This research was qualitative content analysis. The statistical population included experts in the fields of family physicians. Sampling method was targeted and in order to identify qualified people, snowball sampling was used as well. The data collection tool was semi-structured interview, and the researchers exploited thematic analysis in the data analysis. To determine the validity and reliability, the Lincoln and Guba method was used based on four criteria of credibility, transferability, conformability and dependability. Results: Regarding the common areas of medical librarians and family physicians, four concepts were extracted including helping physicians in scientific and professional mastering, upgrading research methodology, upgrading information literacy, and the content of information resources for patient training. Moreover, 4 concepts were identified: appropriate policy-making, education suitability, participation in clinical research, and promotion of the quality of patient training in addition to 6 components of interaction strategies. Conclusion: Strategies for the interaction of medical librarians with family physicians can become practical in areas such as proper policy-making, suitability of education, participation in clinical research, and the improvement of the quality of patient training.

Intrathecal Meperidine Plus Lidocaine for Prevention of Shivering during Cesarean Section

Background

Shivering related to spinal anesthesia may interfere with monitoring and is uncomfortable. The aim of the present study was to investigate low-dose intrathecal meperidine for the prevention of shivering after induction of spinal anesthesia in parturients with cesarean section.

Methods

This was a prospective randomized, double-blind, placebo-controlled trial including 100 parturients, of American Society of Anesthesiologists (ASA) physical status I or II, scheduled for elective cesarean section under spinal anesthesia who were randomly assigned to a meperidine (0.2 mg/kg) plus hyperbaric lidocaine (5%, 75 mg, n = 50; group M) group or a placebo plus hyperbaric lidocaine (5%, 75 mg, n = 50; group L) group. Demographic and surgical data, adverse events, and the mean intensity for each parturient were assessed during the entire study period by a blinded observer.

Results

There were no significant differences between the two study groups regarding the demographic and surgical data (P > 0.05). The incidence of shivering during the entire study period significantly decreased in the group of parturients who received intrathecal meperidine (P = 0.04). There were no significant differences in nausea and vomiting between the two groups.

Conclusions

Low-dose intrathecal meperidine (10 mg) is safe and effective in reducing the incidence and severity of shivering associated with spinal anesthesia in parturients with cesarean section.
