Urinary system stones are the third most common disease of urinary system following urinary infection and prostate pathology. Extracorporeal shockwave lithotripsy (ESWL) is one of the methods used to treat Urolithiasis where shockwaves are transmitted through skin and body organs and crush the stones into small pieces. This is a painful procedure which usually requires analgesics. Each analgesic drug has its own advantages and disadvantages. The present research seeks to study the effectiveness of using diclofenac suppository in order to control pain and reduce need for venous drugs during ESWL procedure. This is a double blind clinical trial. 158 patients resorting to Shahid Hasheminezhad Specialized Center for ESWL were randomly selected to take part in this projects with due consideration of inclusion criteria. The patients were equally divided into the S (diclofenac suppository) and A (placebo) groups. 2 diclofenac suppositories were used in the S group 20 minutes prior to beginning ESWL. Then, ESWL was carried out in supine position using fluoroscopic conduction with standard method. The present research has studied pain scale of patients, operator’s and patient’s satisfaction during the operation and patient’s hemodynamic parameters in three phases prior to, during, and after ESWL. SPSS v.17 was used to study the data and Chi-Square Tests and Repeated Measure ANOVA were used to analyze the results. The level of significance in the present research was set to P-value < 0.05.A review of pain scales across both groups showed that using diclofenac suppository has a significant influence in reducing the pain scale and, hence, need for venous drugs (P-value < 0.05). No significant difference was observed between the two groups in terms of heart beat and blood pressure changes in various times (P-value > 0.05). The results also report different satisfaction levels for patients and operators across the two groups (diclofenac suppository and placebo) (P-value < 0.05). Higher satisfaction levels were observed among both patients and operators in the group receiving diclofenac suppository. A general look at the data yields the conclusion that receiving pain killers (diclofenac suppository) before starting ESWL plays a more efficient role in reducing pain scales of patients and enhancing operators’ satisfaction..
Background: The identification of different factors affecting anesthesia and physiological changes during anesthesia can be effective in improving the quality of anesthesia. Midazolam is a benzodiazepine that has been used for many years for sedation under anesthesia. Stress is also an important factor affecting memory and other physiological changes, such as blood pressure and heart rate. Objectives: his study aimed to investigate the effects of stress on retrograde and anterograde amnesia among patients undergoing general anesthesia. Methods: This multi-center, parallel, stratified, randomized controlled trial was performed on patients undergoing non-emergency abdominal laparotomy. The patients were divided into high- and low-stress groups according to the Amsterdam Preoperative Anxiety and Information Scale. Then, both groups were randomly divided into three subgroups receiving 0, 0.02, or 0.04 mg/kg of midazolam. Recall cards were shown to patients at 4 minutes, 2 minutes, and immediately before injection to determine retrograde amnesia and at 2 minutes, 4 minutes, and 6 minutes after injection to determine anterograde amnesia. Hemodynamic changes were recorded during intubation. The chi-square and multiple regression tests were used to analyze the data. Results: Midazolam injection was associated with the development of anterograde amnesia in all groups (P < 0.05); however, it had no effect on the development of retrograde amnesia (P < 0.05). Midazolam could decrease the systolic and diastolic blood pressure and heart rate during intubation (P < 0.05). Stress also caused retrograde amnesia in patients (P < 0.05); nevertheless, it had no effect on anterograde amnesia (P > 0.05). Stress and midazolam injection could not affect the oxygen levels during intubation. Conclusions: The results showed that midazolam injection could induce anterograde amnesia, hypotension, and heart rate; nonetheless, it had no effect on retrograde amnesia. Stress was associated with retrograde amnesia and increased heart rate; however, it was not associated with anterograde amnesia.
Evaluation the predictive value of perioperative Plasma B-type natriuretic peptide level in arterial switch operation. Plasma B-type natriuretic peptide level was measured before and and 24 hours after surgery in 29 patients with arterial switch operation. We evaluated 29 patients (22 male,76%,7 female 24%) with mean age 67.93±84.09 days (range 6 days to 14months).The mean of BNP level before surgery was 7989.96±9691.94 and increased after surgery to 22391.35±11898.67 and difference between two groups was significant (P=0.003).In linear regression test the BNP did not correlate with sex(r=0.33, P=0.085) and age(r=0.14,P=0.45). Furthermore, BNP did not correlate with duration of mechanical ventilation (r=0.132,P=0.53) , ICU stay (r=0.137,P=0.52) and with lactate level (r=0.41,P=0.054)after operation. During the study 4 patients(13.8%) died and the mean of BNP 24h after operation among them was 35000.00±00.00.using chai-square and fisher exact test the correlation between BNP and death was significant(P=0.001). We implied that BNP level increased 24 hours after arterial switch operation, moreover we denoted it correlated well with the death rate and an increase in B-type natriuretic peptide 24 hours after surgery predicts poor postoperative outcome. However it did not correlate with duration of mechanical ventilation ,ICU stay and lactate level in this patients.
Severe infection with COVID-19 disease can be associated with respiratory failure, kidney disorders, and in more advanced stages, organ failure and death. Unfortunately, there is currently no definitive cure for this disease, and damage to the immune system caused by inflammatory storms leads to widespread and varied complications that make an early diagnosis of the disease difficult. Therefore, eliminating or inhibiting the production of factors involved in inflammatory storms can be effective in improving the clinical condition of patients. According to specialized studies on the role of hemoperfusion in inhibiting advanced levels of COVID-19 disease, the present study was performed to investigate the use of hemoperfusion as a potential treatment option for this disease.
Background: Despite the high acceptability of the extracorporeal shock wave lithotripsy (ESWL) procedure in the treatment of urinary stones at all ages, it is necessary to use a variety of analgesic drugs during the procedure, especially among children. Objectives: We aimed to evaluate the effect of dexmedetomidine-ketamine (DK) and midazolam-ketamine (MK) compounds in the sedation of children (2-6 years old) undergoing ESWL. Methods: This randomized, double-blind clinical trial was performed on children aged 2 to 6 years with renal stones undergoing ESWL. The participants were randomly assigned to the DK and MK regimen groups (dexmedetomidine, 0.05 mcg/kg within 10 minutes infusion; midazolam, 0.05 mg/kg within 3 minutes infusion; ketamine, 0.5 mg/kg bolus injection). The patients were assessed with respect to sedation degree, post-procedure hemodynamic status, recovery time and awakening, and operator satisfaction. Results: Recovery time was significantly shorter in the DK group than in the MK group. Also, the DK regimen was more analgesic than the MK regimen; therefore, the need to repeat ketamine administration was less. There was no difference between the 2 methods in terms of cooperation at the time of separation of children from their parents, patient cooperation during the procedure, average verbal response time and average cooperation time after entering recovery, and operator satisfaction with the operation. No side effects were observed in the 2 groups. Conclusions: Ketamine with dexmedetomidine is associated with greater analgesia and shorter recovery time; however, sedation time was longer (insignificant) in ketamine with midazolam than in ketamine with dexmedetomidine. Thus, ketamine with dexmedetomidine is more preferred.
