Treatments of uremic pruritus: A systematic review.

Till now many treatments attempted to relieve uremic pruritus (UP) though none of them are definite treatment. In this study, we gathered all studies conducted on UP treatment since 2000-2016. We conducted a systematic review by searching the electronic databases (PubMed, Scopus, and Google scholar). Patients were with chronic kidney disease who complained of UP. Clinical trials and pilot studies in English and Persian which were done on patients with ESRD who complained of itching between 2000 till 2016 were gathered. A total of 166 articles were collected. After excluding articles 41 articles were remaining. Then UP treatments classified into two main groups: Medical (chemical and herbal medicine) and non-medical. Most studies measured UP by VAS scoring system in which patients described the severity. This scoring system is individual dependent. There are lots of studies on UP treatment though there are lots of controversies in studies. Finding a definite cure for this unpleasant symptom can improve patients' quality of life. Conducting further studies for each treatment on larger population is essential to improve quality of life among the end stage renal disease patients.

Effect of chamomile aromatherapy with and without oxygen on pain of women in post cesarean section with spinal anesthesia: A randomized clinical trial.

Background: Pain is the most common side effect in cesarean section with spinal anesthesia. It seems that oxygen therapy and chamomile aromatherapy may diminish pain. The present study was conducted to examine and compare the effect of chamomile aromatherapy with and without oxygen on the severity of pain of women following cesarean section surgery with spinal anesthesia. Methods: The present randomized clinical trial study was carried out on 136 women undergoing cesarean section surgery with spinal anesthesia at Imam Sajad Hospital, Yasuj, Iran in 2020. The eligible women were assigned into four 34-member groups including oxygen therapy plus aromatherapy, oxygen therapy, aromatherapy, and control via block randomization. Each of these interventions were performed 6, 6.30 and 7 h post operation. In the first intervention group, one drop of chamomile essential oil with distilled water was poured into a small nebulizer using a simple mask connected to 6 L of oxygen. The second intervention group received oxygen without chamomile aromatherapy at similar times, and the third intervention group received chamomile aromatherapy without oxygen. The control group received only routine interventions. The instrument used in the research was visual analog scale which was completed by the researcher 6, 12, 18 h after cesarean section. The data were analyzed by the SPSS software version 20. Results: There was a significant difference in the intensity of pain of patients between the various groups of study following the interventions (P < 0.001). Pain intensity reduced significantly in the group receiving combined intervention of chamomile aromatherapy plus oxygen compared to the other three groups. Moreover, the pain intensity diminished more in the groups undergoing each of these interventions alone as compared to the control group (P < 0.05). Conclusions: The combined intervention of chamomile aromatherapy with oxygen was more effective than each of the chamomile aromatherapy and oxygen interventions alone in reducing the pain of cesarean section patients though each intervention alone was still effective in lowering pain post-operation.

Comparing intensity of pain due to intravenous injection of sodium thiopental, propofol, diazepam, and etomidate during induction of general anesthesia.

Aim: The aim of the present study was to compare the pain intensity due to intravenous injection of sodium thiopental, propofol, diazepam, and etomidate during the induction of general anesthesia. Methods: This was a non-controlled quasi-experimental double-blinded study performed on eligible patients referred to the operating room of Shahid Beheshti Hospital in Yasouj. A total of 200 patients were randomly selected by convenience sampling and based on a table of random numbers generated on a computer. They were then randomly divided into four intervention groups based on random blocks (sodium thiopental, propofol, etomidate, and diazepam). Finally, the collected data were analyzed using descriptive as well as analytical statistical tests such as Chi-square, analysis of covariance (ANCOVA), and Bonferroni post hoc test were analyzed in SPSS ver. 24. Results: The results of the present study showed that the diazepam group experienced the highest pain intensity (8.42) compared to other groups, which was statistically significant (P = 0.001). Also, the sodium thiopental group experienced the highest pain (6.92) after the diazepam group, which was also statistically significant as compared to the other remaining two groups (P = 0.001). Propofol and etomidate groups experienced the lowest pain intensity (3.30 and 3.26, respectively). Conclusion: The present study revealed that the use of diazepam and sodium thiopental as anesthetic drugs was generally associated with greater pain intensity during injection and less hemodynamic stability. The results of the present study indicated that propofol and etomidate are preferred over diazepam and sodium thiopental in abdominal and gastrointestinal surgeries, considering their less pain intensity and fewer hemodynamic changes.

Role of vitamin D in oxidative stress modulation in end-stage renal disease patients: A double-blind randomized clinical trial.

INTRODUCTION: Oxidative stress is considered as important actor in uremia-associated morbidity and mortality in hemodialysis (HD) patients. We aimed to evaluate the role of vitamin D supplementation on oxidative stress parameters in this group. METHODS: This double-blind randomized clinical trial was conducted on HD patients who were randomly allocated into intervention (n = 40) or control groups (n = 38) for 10 weeks. Blood samples were taken before and at the end of the trial to measure serum 25-hydroxyvitamin D (25(OH)D), malondialdehyde (MDA), glutathione peroxidase (GPx), catalase (CAT), and superoxide dismutase (SOD). Data were analyzed using SPSS, and P value <0.05 was considered to be statistically significant. FINDINGS: Out of the 78 patients with a mean age of 44.7 ± 13.0 years, 55.1% were men. At the commencement of the study, there was no difference with respect to serum 25(OH)D levels in our groups (P = 0.575), but during the study it was significantly elevated in the intervention group (18.1 ± 9.1 vs. 31.7 ± 12.9, P < 0.0001). Serum antioxidative enzymes activity (GPx, CAT, and SOD) had significantly increased after vitamin D supplementation in the intervention group (P < 0.05). Furthermore, MDA levels was significantly reduced only in the intervention group (31.7 ± 18.0 vs. 24.7 ± 7.7, P = 0.018). DISCUSSION: Regular consumption of vitamin D can increase the GPx, CAT, SOD, and reduce the MDA plasma levels in HD patients. Since no adverse effects of vitamin D supplementation was reported by the patients; hence, it can be prescribed for HD patients.

Comparison of Duration of Spinal Anesthesia with Lidocaine or Lidocaine plus Epinephrine between Addicts and Non-addicts.

BACKGROUND: Duration of spinal anesthesia depends on the type of anesthetic agent, dosage and additive materials such as epinephrine, ephedrine and opioid. We compared the duration of spinal anesthesia with lidocaine 5% with or without epinephrine in addict and non-addict patients undergoing inferior limb fracture surgery. METHODS: This single blinded randomized clinical trial was performed on 201 males (height ranged 150-180 cm) who referred to the Shahid Bahonar Hospital of Kerman for the inferior limb fracture. Their physical class was matched to the American association standard class 1 and 2, and they were appropriate candidates for the spinal anesthesia. The addict or non-addict groups were each divided into two subgroups. 75 mg of 5% lidocaine was prescribed for one subgroup, and the other subgroup received 75 mg of 5% lidocaine plus 0.2 mg epinephrine. The level of primary anesthesia was elevated to T6. Duration of returning to the 4 primary sensory levels was measured since baseline. FINDINGS: A significant increase in the duration of anesthesia level in both addict and non-addict patients receiving lidocaine plus epinephrine was observed compared to the subgroups receiving lidocaine alone (P < 0.01). Duration of decrease in sensory level in addict subgroups receiving lidocaine or lidocaine plus epinephrine was lower compared to non-addict patients (P < 0.001). In addict subgroup receiving lidocaine alone, a significant decrease was observed in the time needed for decrease in sensory level (P < 0.01). CONCLUSION: According to the results of this study, regardless of the anesthetic agent being used, duration of spinal anesthesia was shorter in addict patients compared to non-addict ones. Addition of epinephrine to lidocaine 5% increased the duration of spinal anesthesia in both addict and non-addict patients.
