A Comparison of the Effects of Chlorhexidine and Sodium Bicarbonate Mouthwashes on COVID-19-Related Symptoms.

Background: Some studies have reported that mouthwashes can decrease the viral load in the mouth, but there is not much information about the effectiveness of mouthwashes on coronavirus disease 2019 (COVID-19). This study was conducted to compare the impact of using two types of mouthwash, chlorhexidine and sodium bicarbonate, on COVID-19 symptoms and infection. Materials and Methods: The present three-group, double-blind clinical trial examined 116 operating room nurses and anesthesia personnel of certain hospitals of Isfahan University of Medical Sciences, Isfahan, Iran. The participants were randomly assigned to three groups: intervention group 1 (chlorhexidine mouthwash), intervention group 2 (sodium bicarbonate mouthwash), and the control group (placebo). Mouthwash was used twice a day (morning and night) for 2 weeks. The participants were monitored in terms of COVID-19-related symptoms for 4 weeks, from the first day of mouthwash use. Results: Fisher's exact test indicated a significant difference between the chlorhexidine and control groups in terms of the onset of COVID-19-related symptoms (p = 0.02). There was no significant difference in the symptoms of COVID-19 between the groups, but the groups were significantly different in terms of all symptoms at a 4-week interval (p = 0.04). Furthermore, headache was less observed in the chlorhexidine (p = 0.007) and sodium bicarbonate (p = 0.03) groups compared to the control group. Conclusions: The use of 0.2% chlorhexidine mouthwash can decrease the onset of COVID-19-related symptoms in health-care workers. In addition, this mouthwash can partially reduce the symptoms of this disease in comparison to the control and sodium bicarbonate groups.

Nurses' viewpoints on factors affecting ostomy care: A qualitative content analysis.

AIMS: Ostomy plays an important role in management of medical conditions, especially postoperative status of colorectal and bladder cancers. Nurses who have the highest contact level with these patients, face many situations while providing care and need to acquire adequate knowledge and practice responding to patients' needs. The aim of this study was to explore the lived experiences of nurses in caring of abdominal ostomy patients. DESIGN: A qualitative content analysis study. METHODS: In this qualitative content analysis study, 17 participants were selected using purposeful sampling method and data were collected through in-depth and semi-structured interviews. Data analysis was done using conventional content analysis method. RESULTS: Analysis of the findings led to the emergence of 78 sub-subcategories, 20 subcategories and seven main themes, including 'Inefficient educational system', 'Nurse Characteristics', 'Workplace challenges', 'Nature of ostomy care', ' Counseling and preparation of patients for surgery', 'Acquaintance with ostomy complications', and 'Proper planning of patient education'. Results showed that nurses in surgical wards provide non-special ostomy care due to lack of sufficient knowledge and skills and absence of up-to-date and local clinical guidelines which is vital to provide evidence-based scientific care and avoid unfounded and arbitrary care.

Effect of Rectal Midazolam on Pain, Stress, and Cooperation of Patient during Urodynamic Test in Women: A Randomized Clinical Trial.

PURPOSE:  The urodynamic study is an invasive test, and causes pain and stress in the patient. We have investigated the effect of rectal midazolam sedation on the pain, stress, and cooperation of women performing urodynamic study.  Materials and Methods: At the present randomized clinical trial (RCT) from January to July of 2021 a total of 84 women were prospectively randomized to undergo urodynamic study with or without sedation. The primary outcome of interest was experienced pain during urodynamic study. In the intervention group, after monitoring baseline vital signs (heart rate, blood pressure, O2 saturation), sedation was done with rectal midazolam at a dose of 0.3 mg/kg (maximum 15 mg). Completing the procedure, after recovery from sedation patients were asked to fill a self-assessed visual analog pain scale (VAS, 0-10), 5-point visual stress scale (1-5) and, patient collaboration level during urodynamic study was evaluated by nurse with a researcher-made tool (0-3). In the control group test was performed in routine practice with no sedation. Baseline vital signs measured pre and intra-procedural time, as well as their experienced pain, stress, and cooperation levels were recorded.  Results: 84 female cases were evaluated. In terms of comparison of changes in pre and intra-test physiologic parameters, results showed that there were no significant differences between the two groups for all physiologic parameters: SBP, DBP, PR, SpO2. Analysis of the pain score showed that it was lower in the intervention group, and there was a significant difference in pain score between the two groups (P =.024). While the stress and corporation scores were not reported statistically significant (P=.388 and P=.955, respectively). CONCLUSION:   Sedation with rectal midazolam in adult women before UDS is safe and effective in reducing pain but is not effective in reducing stress and increasing cooperation. The amount of pain based on the visual analog pain scale is mild and although this method is safe, its use routinely is not recommended.

Labial Cellulitis and Suprapubic Urine Leakage after Midurethral Sling: A Rare Presentation of Unrecognized Bladder Neck Perforation.

Retropubic midurethral sling (MUS) is safe and effective surgery used for the treatment of stress urinary incontinence in women. Bladder neck perforation is a rare intraoperative complication. If this complication missed in intraoperative cystoscopy may have serious morbidity. A 52-year-old woman underwent a retropubic MUS. She presented with early and unusual symptoms such as suprapubic and labial cellulitis and urine leakage through the suprapubic incision 1 week after surgery which was due to a missed bladder neck perforation during surgery. In cystoscopy after MUS revealed mesh traversing the bladder neck and it was removed. The missed bladder perforation may have early and unusual symptoms and cystoscopy must be done more carefully and obsessively in patients with risk factors.
