ABSTRACT
Background: The management of preoperative anxiety in pediatric patients, as well as its implications, has remained challenging for anesthesiologists. In this study, we compared the safety and efficacy of intranasal dexmedetomidine, midazolam, and ketamine as surgical premedication in children. Methods: This double-blinded randomized clinical trial was conducted at two tertiary hospitals in January 2014, on 90 children aged between 2-7 years old. The participants' American Society of Anesthesiologists (ASA) physical status was I or II, and they were scheduled for elective unilateral inguinal herniorrhaphy. Using the block randomization method, the patients were randomly assigned to three groups, each receiving intranasal dexmedetomidine (2 µg/Kg), midazolam (0.2 mg/Kg), and ketamine (8 mg/Kg) 60 min before induction of anesthesia. Anxiety and sedation state were evaluated before drug administration, and then every 10 min for the next 50 min. Parental separation anxiety, mask acceptance, postoperative agitation, pain, nausea, and vomiting were also recorded and compared between these groups. All the statistical analyses were performed using SPSS software (version 21.0). P<0.05 was considered statistically significant. Results: Ketamine indicated the strongest sedative effect 10, 20, and 30 min after administration of premedication (P<0.001, P=0.03, P=0.01, respectively). However, dexmedetomidine was more effective than other drugs after 40 and 50 min (P<0.001). Other variables indicated no statistically significant difference. Conclusion: In case of emergencies, intranasal ketamine, with the shortest time of action, could be administered. Intranasal dexmedetomidine, which was revealed to be the most potent drug in this study, could be administrated 40-50 min before elective pediatric surgeries.Trial registration number: IRCT2013081614372N1.

Background: The effectiveness of continuous wound infiltration (CWI) as a postoperative pain-control technique has been shown in many surgical procedures. This study investigates the effect of CWI of local anesthetic on postoperative pain control in intertrochanteric fracture patients undergoing hip nailing surgery. Methods: In this randomized clinical trial, 48 patients who were scheduled for hip nailing surgery were randomly assigned to receive (n = 24) or not receive (n = 24) bupivacaine infusion through a catheter inside the surgical wound, postoperatively. Pain intensity (NRS), required dose of morphine, and drug-related complications within 24 hours of the intervention were assessed and compared. Results: Pain intensity was significantly lower in the bupivacaine group both during the recovery room stay and in the ward in the first 24 hours after the procedure (P < 0.001). In the recovery room, the control group patients had a higher morphine consumption compared to the bupivacaine group (P < 0.001) and requested it earlier than the bupivacaine group (60 (45-60) vs. 360 (195-480) minutes) (P < 0.001). In the ward, all control group patients used the PCA morphine pump, while only 54% of the bupivacaine group self-administered morphine through the pump, with a significantly lower total morphine consumption (1 (0-2) vs. 10 (5-14) mg, P < 0.001). None of the patients in the bupivacaine group required additional morphine, while 37.5% of the control requested additional morphine (P=0.002). Altogether, the control group had a higher total morphine consumption compared to the bupivacaine group in the first 24 hours (10.5 (6-15.5) vs. 1 (0-2) mg, P < 0.001). Conclusion: CWI of bupivacaine helps better pain reduction during the early postoperative hours while it reduces opioid consumption, minimizes nausea and vomiting, and improves patient satisfaction.

OBJECTIVES: Numerous studies have been conducted to investigate the effects of preoperative hyponatremia on survival after liver transplantation. The variable findings underscore the necessity for performing a systematic review to elucidate the potential effects of preoperative hyponatremia. MATERIALS AND METHODS: We searched PubMed, Scopus, Web of Science, Science Direct, Cochrane Library, and reference lists of articles for observational cohort studies that reported association between preopera-tive hyponatremia and survival after liver transplant in adults regardless of publication year. We used the random-effect model to pool the extracted data for meta-analysis. RESULTS: Meta-analyses of mean difference in serum sodium levels showed that nonsurviving recipients had 2.58 mEq/L lower preoperative serum sodium levels than surviving recipients (0.02; 95% CI, .33-4.83). Two observational methods were used to assess survival after liver transplant of patients with preoperative hyponatremia. According to meta-analyses, no dif-ference in survival was shown between recipients with and without preoperative hyponatremia (sodium> 130 mEq/L) (≤1 month : 0.69 [95% CI, 0.9-1.07], 3-month survival: 0.54 [95% CI, 0.95-1.02]). Second, when we compared posttransplant survival of recipients with preoperative hypo-natremia versus those with normal serum sodium levels (sodium = 130-145 mEq/L), we found that recipients with preoperative hyponatremia had lower survival after liver transplant than those with normal preoperative serum sodium levels. CONCLUSIONS: Liver transplant recipients with preop-erative hyponatremia probably have shorter survival posttransplant than those with normal preoperative serum sodium level.

OBJECTIVES: The purpose of this study was to determine the therapeutic effect of the Punica granatum (PG) flower on recurrent aphthous stomatitis in comparison with corticosteroid therapy. MATERIALS AND METHODS: This cross-over randomized clinical trial was conducted on the patients who had been referred to Shiraz Dental School for their RAS in 2021. All the participants used both P. granatum flower tablets and Triadent a month apart for wash-out time and all compared themselves. In the experimental group, 30 patients received pomegranate flower tablets, three tablets daily, for 6 days. In the control group, oral paste Triadent has been prescribed three times a day for 6 days. The visual analog scale (VAS) and the size of RAS were evaluated on Days 0-6. Data were analyzed by SPSS version 21. The Wilcoxon test was used. RESULTS: The mean age of participants was 27.8 ± 14.77 years old. In this study, 15 patients (50%) were men and 15 patients (50%) were women. The mean value of VAS after using prescribed treatment in both evaluated groups on all days was significantly different such that the VAS values were lower for PG flower tablets than Triadent (p value < 0.05). The size of oral lesions in participants who used PG flower tablets was significantly less than those who used Triadent on all evaluation days (p value < 0.05) except on Day 1 (p value = 0.29). The descending slope of VAS from Days 1 to 6 for both Triadent and PG flower tablet users was significant and noticeable. (p value < 0.05). CONCLUSION: According to the result of this study, both P. granatum flower tablet and Triadent are useful in reducing the size, period of healing, and VAS of patients with RAS, but the PG flower tablet is more effective.

Background: There have been few studies on the effect of Kegel exercises on the treatment of functional constipation in children. Hence, the present study investigated the add-on role of Kegel exercises in children with functional constipation. Methods: This clinical trial was conducted on children with functional constipation, according to Rome IV, who were referred to the pediatric department of Imam Reza Clinic (Shiraz, Iran) in 2022. The sample consisted of 64 children who were randomly assigned to either the intervention or the control groups. In the control group, a pediatrician administered conventional therapy, including diet training, defecation training, and polyethylene glycol (PEG) syrup (0.7 g/Kg daily). In the treatment group, in addition to conventional therapy, a pediatrician taught Kegel exercises to the child both verbally and in writing in the presence of their parents. To investigate the effectiveness of the intervention, frequency of defecation, defecation time, assistance used for defecation, incomplete emptying, unsuccessful defecation, abdominal pain, and painful defecation were selected as the outcomes. Independent sample t test was used for continuous variables. Categorical variables were reported as frequency and percentages. To examine the difference in categorical outcome variables, Wilcoxon (pre and post), Chi square, and Fisher exact tests were used. Data were analyzed using SPSS software version 21. P<0.05 were considered statistically significant. Results: Twenty-seven (88.4%) patients in the Kegel exercise group reported a defecation time of less than 5 min, while only 12 (37.5%) patients in the control group reached this time, and this difference was statistically significant (P=0.001). Moreover, patients in the treatment group showed significant improvements in terms of incomplete emptying of stool, unsuccessful defecation, abdominal pain, and painless defecation (P=0.001, P=0.001, P=0.001, P=0.037, respectively). After intervention, the use of laxatives, digits, or enemas to assist defecation was not significantly different between the groups (P=0.659). Conclusion: Kegel exercise was an effective adjunctive treatment for pediatric functional constipation.Trial Registration Number: IRCT20230424057984N1.

BACKGROUND: Despite the beneficial effects, RBC transfusion can be associated with infectious and non-infectious complications in critically ill patients. OBJECTIVES: Investigate current RBC transfusion practices and their effect on the clinical outcomes of patients in intensive care units (ICUs). DESIGN: Retrospective observational study. SETTING: Three mixed medical-surgical adult ICUs of a large academic tertiary hospital. PATIENTS AND METHODS: From March 2018 to February 2020, all adult patients admitted to medical or surgical ICU. Patients who received one or more RBC transfusions during the first month of ICU admission were included in the "transfusion" group, while the remaining patients were assigned to the "non-transfusion" group. MAIN OUTCOME MEASURES: Mortality and length of ICU and hospital stay. SAMPLE SIZE: 2159 patients. RESULTS: Of 594 patients who recieved transfusions, 27% of patients received red blood cell (RBC) products. The mean pre-transfusion hemoglobin (Hb) level was 8.05 (1.46) g/dL. There was a significant relationship between higher APACHE II scores and ICU mortality in patients with Hb levels of 7-9 g/dL (OR adjusted=1.05). Also, ICU mortality was associated with age (OR adjusted=1.03), APACHE II score (OR adjusted=1.08), and RBC transfusion (OR adjusted=2.01) in those whose Hb levels were >9 (g/dl). CONCLUSION: RBC transfusion was associated with an approximately doubled risk of ICU mortality in patients with Hb>9 g/dL. High APACHE II score and age increase the chance of death in the ICU by 8% and 3%, respectively. Hence, ICU physicians should consider a lower Hb threshold for RBC transfusion, and efforts must be made to optimize RBC transfusion practices. LIMITATIONS: Single-center and retrospective study.

Background: Even though a few years have passed since the coronavirus disease 2019 (COVID-19) outbreak, information regarding certain aspects of the disease, such as post-infection immunity, is still quite limited. This study aimed to evaluate post-infection protection and COVID-19 features among healthcare workers (HCWs), during three successive surges, as well as the rate of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) reinfection, reactivation, re-positivity, and severity. Methods: This cross-sectional population-level observational study was conducted from 20 April 2020 to 18 February 2021. The study population included all HCWs in public or private hospitals in Fars Province, Southern Iran. The infection rate was computed as the number of individuals with positive polymerase chain reaction (PCR) tests divided by the total number of person-days at risk. The re-infection was evaluated after 90 days. Results: A total of 30,546 PCR tests were performed among HCWs, of which 13,749 (61.94% of total HCWs) were positive. Considering the applied 90-day threshold, there were 44 (31.2%) cases of reactivation and relapse, and 97 (68.8% of infected and 1.81% of total HCWs) cases of reinfection among 141 (2.64%) diagnosed cases who experienced a second episode of COVID-19. There was no significant difference in symptoms (P=0.65) or the necessity for ICU admission (P=0.25). The estimated protection against repeated infection after a previous SARS-CoV-2 infection was 94.8% (95% CI=93.6-95.7). Conclusion: SARS-CoV-2 re-positivity, relapse, and reinfection were rare in the HCW population. After the first episode of infection, an estimated 94.8% protection against recurring infections was achieved.

PURPOSE: Prolonged mechanical ventilation (MV) subjects multiple trauma patients to ventilator-induced diaphragmatic dysfunction. There is limited evidence on the predictive role of diaphragm ultrasound (DUS) for weaning success in multiple trauma patients. Therefore, we evaluated Ultrasound of the diaphragm as a valuable indicator of weaning outcomes, in trauma patients. MATERIAL AND METHODS: This prospective cohort study included 50 trauma patients from September 2018 to February 2019. DUS was performed twice: upon ICU admission and the first weaning attempt. The diagnostic accuracy of indexes was evaluated by ROC curves. RESULTS: The study included patients with a mean age of 35.4 ± 17.37, and 78% being male. The median injury severity score was 75 (42-75). The failure group exhibited significantly lower right diaphragmatic excursion (DE) compared to the success group (P = 0.006). In addition, the failure group experienced a significant decrease in both right and left DE from admission to the first attempt of weaning from MV (P < 0.001). Both groups showed a significant decrease in inspiratory and expiratory thickness on both sides during weaning from MV compared to the admission time (P < 0.001). The findings from the ROC analysis indicated that the Rapid shallow breathing index (RSBI) (Sensitivity = 91.67, Specificity = 100), respiratory rate (RR)/DE (Right: Sensitivity = 87.5, Specificity = 92.31), and RR/TF (Thickening Fraction) (Right: Sensitivity = 83.33, Specificity = 80.77) demonstrated high sensitivity and specificity in predicting weaning outcome. CONCLUSION: In the context of patients with multiple trauma, employing DUC and assessing diaphragmatic excursion, thickness, RR/DE index, RR/TF index, and RSBI can aid in determining successful ventilator weaning.

OBJECTIVES: This study aimed to compare the efficacy of labetalol and lidocaine in tympanoplasty surgery, specifically evaluating their impact on hemodynamic changes and perioperative outcomes. METHODS: A randomized controlled trial was conducted with 64 patients scheduled for tympanoplasty. Patients were randomly assigned to receive either 0.5-2â¯mg/min labetalol or 1.5â¯mg/kg/h lidocaine 1% to achieve controlled hypotension during surgery. The efficacy of the drugs was assessed by comparing the Mean Arterial Pressure (MAP), surgeon's satisfaction, time to target MAP, bleeding volume, postoperative pain scores, the need for analgesic medication in recovery, sedation, and other additional parameters. RESULTS: The hemodynamic parameters showed a similar trend over time in both the labetalol and lidocaine groups. The median bleeding volume in the labetalol group (10 cc) was lower than that in the lidocaine group (30 cc), although this difference was not statistically significant (pâ¯=â¯0.11). Similarly, surgeon's satisfaction level, pain intensity, and sedation level in the recovery room did not show statistically significant differences between the two groups (pâ¯>â¯0.05). The duration of surgery, recovery stay, and extubation time also did not significantly differ between the groups. Both medications took approximately the same time (20â¯min) to reach the target MAP and exhibited comparable hemodynamic responses (pâ¯>â¯0.05). CONCLUSION: Both labetalol and lidocaine effectively achieved controlled hypotension during tympanoplasty surgery, thereby improving surgical conditions. The choice of medication should be based on individual patient characteristics and the anesthesiologist's judgment. LEVEL OF EVIDENCE: II.

OBJECTIVE: Nausea and vomiting after surgery are the most common complications. Therefore, we performed this study to compare the effect of ondansetron and haloperidol on nausea and vomiting after laparoscopic cholecystectomy. PATIENTS AND METHODS: In this randomized clinical trial, 60 patients candidates for elective laparoscopic cholecystectomy were allocated to haloperidol (0.05 mg/kg, n = 30) and ondansetron (0.15 mg/kg, n = 30) groups. An Ocular Analog Scale was used to assess postoperative nausea and vomiting. Every 15 minutes in the recovery room, heart rate and blood pressure were measured up to 6 hours after surgery. In addition, patient satisfaction was assessed postoperatively. RESULTS: Haloperidol and ondansetron have the same effect on postoperative nausea and vomiting in the recovery room and ward. It was found that the trend of Visual Analog Scale variable changes in the recovery room was similar in the haloperidol and ondansetron group ( P = 0.58); it was also true for the ward ( P = 0.79). Comparing the length of stay in a recovery room in the 2 groups was not statistically significant ( P = 0.19). In addition, the 2 groups did not differ in satisfaction postoperatively ( P = 0.82). CONCLUSION: Haloperidol and ondansetron had an equal effect on reducing nausea and vomiting in the recovery room and ward after laparoscopic cholecystectomy. Patient satisfaction and length of stay in the recovery room did not differ between groups.

INTRODUCTION: The management of postoperative pain, particularly in younger children, presents a challenge due to their limited ability to articulate the intensity of pain, lower pain threshold, and restricted availability of approved analgesics for pediatric use. Peripheral nerve blocks may be favored over neuraxial blocks because they allow quicker mobilization after surgery. OBJECTIVE: The present study aims to investigate the potential impact of adding dexmedetomidine to a local anesthetic (bupivacaine) on the analgesic efficacy in dorsal penile nerve block in hypospadias repair surgery. METHOD: In this prospective double-blinded clinical trial, 50 children aged between 6 months and 6 years old undergoing hypospadias repair surgery participated. Analgesia was administered through a dorsal penile nerve block (DPNB) at the end of surgery. Participants were divided into two groups; one received bupivacaine alone, and the other received dexmedetomidine and bupivacaine in DPNB. Pain and sedation levels were assessed with FLACC score and MOAA/S score, respectively, at 0,1,2 and 4 h after surgery. Vital signs and adverse effects were also recorded, including hemodynamic changes, nausea, and vomiting. RESULT: There was no statistically significant difference in demographic variables. As illustrated in Figure, the median of FLACC score in group BD was significantly lower compared to group B at every measured time point. MOAA/S score was significantly lower in group BD than in group B (p < 0.001), indicating a higher sedation level. None of the participants in either group experienced any adverse effect except for vomiting, which was not statistically significant (8 % in group B vs. 4 % in group BD, p > 0.999). DISCUSSION: Several studies have documented the supplementary analgesic properties of dexmedetomidine when used in conjunction with local anesthetic during various surgical procedures and nerve blocks. The present study provides evidence for the additional analgesic efficacy of dexmedetomidine and bupivacaine in the context of dorsal penile nerve block during hypospadias repair surgery while not yielding any significant adverse outcomes. Although the patients in our study were monitored for 4 h in the postanesthesia care unit (PACU), conducting a more comprehensive assessment of patients is advisable. CONCLUSION: The findings of our study indicate that incorporating dexmedetomidine alongside bupivacaine in dorsal penile nerve block during hypospadias repair surgery may lead to enhanced management of postoperative pain. The lack of adverse effects implies it may be a potentially safe supplementary pain reliever for surgical procedures.

Background: Several adjuvants, added to local anesthetics, were suggested to induce an ideal regional block with high-quality analgesia. The purpose of this study was to evaluate the particular blocking properties of low-dose bupivacaine in combination with meperidine and fentanyl in spinal anesthesia during Cesarean sections. Methods: A randomized, double-blind clinical trial was conducted at Hafez Hospital affiliated with Shiraz University of Medical Sciences (Shiraz, Iran) from February 2015 to February 2016. A total of 120 pregnant women, who underwent spinal anesthesia during elective Cesarean section were enrolled in the study. Based on block-wise randomization, the patients were randomly assigned to three groups, namely "B" group received 2 mL bupivacaine 0.5% (10 mg), "BM" group received 8 mg bupivacaine and 10 mg meperidine, and "BF" group received 8 mg bupivacaine and 15 µg fentanyl intrathecally. The block onset, the duration of analgesia, and the time of discharge from the post-anesthesia care unit (PACU) were all assessed. Data were analyzed using SPSS software version 21, and P<0.05 were considered statistically significant. Results: The mean duration of motor blocks in the B group (150 min) were significantly higher than the BM (102 min) and BF (105 min) groups (P<0.0001). In both the BM and BF groups, the duration of sensory and motor blocks was the same. The length of stay in the PACU was significantly longer in the B group (P<0.001) than the BM and BF groups. When meperidine or fentanyl was added to bupivacaine, the duration of the analgesia lengthened (P<0.001). Conclusion: Intrathecal low-dose spinal anesthesia induced by bupivacaine (8 mg) in combination with meperidine and/or fentanyl for Cesarean section increased maternal hemodynamic stability, while ensuring effective anesthetic conditions, extending effective analgesia, and reducing the length of stay in PACU.Trial Registration Number: IRCT2015013119470N14.

Background and Goal: Laryngeal mask airway (LMA), a supraglottic device for airway management and ventilation, is used both in emergencies, out of the operating room, and in the operating room during general anesthesia. This study aims to compare the success rate and complications of the classic insertion method (with a semi-inflated cuff) and another technique using the index and middle fingers of the second hand to prevent retroversion of the mask tip (alternative method). Methods and Materials: In total, 288 patients scheduled for short-time ophthalmologic elective surgeries under general anesthesia were randomly allocated to two groups for LMA placement; group C, classical method (with semi-inflated cuff), and group A, alternative method. Difficulty in placement, insertion duration, and the number of attempts were studied. Assessment of pharyngolaryngeal complications (blinded assessor) was made at the time of LMA removal. Findings: The success rate of LMA insertion in the classic group with first, second, and third attempts were 86.3%, 93.5%, and 94.2%, respectively, whereas in the alternative group these values in the first and second attempts were 98.6% and 100%, respectively, and there was no need for the third attempt. Insertion time was not significantly different. There was no meaningful difference between the rate of the bloody streak on the mask (P = 0.37) and the incidence of sore throat (P = 0.048) in the two groups of the study. Conclusion: This newly introduced technique can be considered as an alternative method when a difficult insertion situation is suspected or the classic technique of insertion has failed.
ABSTRACT
Childhood dyslipidemia is considered a major worldwide health issue. Identification of children with dyslipidemia is notably essential for healthcare providers in establishing and releasing recommendations for the management and prevention of future CVD. In the present study, we provided reference values for the lipid profile from Kawar (a city in the south of Iran) cohort of healthy children and adolescents aged 9-18 years. 472 subjects (234 girls and 238 boys) contributed to the current prospective cohort study using a systematic random sample stratified by age. Fasting lipid levels were measured by enzymatic reagents. Dual-energyX-ray absorptiometry (DEXA) was used to evaluate puberty based on the Tanner stages. LMS Chart Maker and Excel software were used to construct the gender-specific reference plots showing the 3, 10, 25, 50, 75, 90, and 97th percentiles of BMI, cholesterol, TG, HDL, TC, LDL, and non-HDL. The outcomes revealed that concentrations of TC, LDL, and non-HDL were drastically greater in girls as compared to boys. TG increased with age in both genders, while HDL, TC, LDL, and non-HDL declined. We also observed that puberty was associated with higher lipid values in boys and girls except for TG in boys. Our study prepared age- and sex-specific reference intervals for the lipid profile in Iranian children and adolescents. Converted to age and gender percentiles, these reference intervals are expected to serve as an effective and consistent tool for doctors to identify dyslipidemia among children and adolescents.
ABSTRACT
BACKGROUND: The prevalence of resistant hospital infections in the intensive care unit (ICU) increases mortality and antibiotic resistance. COVID-19 pandemic may have unintended impact on nosocomial infections (NI) and the prevalence of resistant microorganism. METHODOLOGY: The present non-interventional study was performed by a pre and a post survey each lasting 8 months before (March-October 2019) and after (March-October 2020) the onset of COVID-19 pandemic in three ICU's, not allocated to COVID-19 patients, in Nemazee Hospital, Shiraz, Iran. The rates of the following nosocomial infections were compared at pre- and post-pandemic period: ventilator associated pneumonia (VAP), central line associated blood stream infection (CLABSI), catheter-associated urinary tract infections (CAUTI) and incidence of multiple drug resistance (MDR) pathogens. RESULTS: Pre-pandemic and pandemic incidence of VAP was 23.5 and 17.2 cases per 1000 device-days, respectively; an absolute decrease of 27%. The main reason for the decrease in the rate of VAP during the pandemic was a significant decrease in the rate of VAP caused by Acinetobacter baumannii; from 39 to 17% in total VAP episodes. The rate of VAP associated with other microorganisms remained relatively unchanged from 14.2 cases in pre-pandemic period to 14.3 cases per 1000 MV-days during the pandemic (P = 0.801). Pre-pandemic incidence of CLABSI was 7.3 cases and, in pandemic period, was 6.5 cases per 1000 device-days (IRR = 0.88, 95% CI 0.43-1.73, P = 0.703). Pre-pandemic incidence of CAUTI was 2 and in pandemic period, was 1.4 cases per 1000 device-days (IRR = 0.70, 95% CI 0.22-1.98, P = 0.469). CONCLUSION: The results of the present study showed a decrease in the incidence of VAP in critically ill non-COVID-19 patients during the pandemic compared to before the pandemic, especially regarding Acinetobacter baumannii.

AIMS: In this study, we aimed to appraise the effects of interrupting (discontinuing) vs. continuing Angiotensin receptor blockers (ARBs) and Angiotensin-Converting Enzyme Inhibitors (ACEIs) on the hemodynamic changes of patients during and after cataract surgery. METHODS AND MATERIALS: Patients aged 40-70 years, American society of anesthesiologist (ASA) class II, taking ACEI/ARB medications, who were admitted to Khalili hospital (Shiraz, South of Iran) for cataract surgery, were enrolled in the study. Patients were randomly divided into two groups for continuing or withdrawing the use of ACEI/ARBs. Group 1 included the patients who continued ACEI/ARB administration, and group 2 included those who discontinued them before surgery. In the operating room, relevant demographic information was collected in addition to the data on patients' basic clinical status, including heart rate and blood pressure, before induction of anesthesia, during, and after that. The collected data were analyzed using SPSS 21, and p-values < 0.05 were considered statistically significant. RESULTS: Any significant differences were not revealed in demographic variables (age, sex, diabetes, hypertension, Myocardial infarction, Smoking, and duration of drug therapy) between the two groups. Time effect was significant (p<0.001) for systolic blood pressure, diastolic blood pressure, and heart rate, and interaction between time*group was not significant (p = 0.431, p = 0.566, and p = 0.355) for systolic blood pressure, diastolic blood pressure, and heart rate. However, the group effect wasn't significant (p=0.701, p=0.663, and p=0.669) for systolic blood pressure, diastolic blood pressure, and heart rate. CONCLUSION: It seems that in some minor surgeries, such as cataract surgery, withdrawal or continuation of ACEIs/ARBs have no significant effect on the hypotension and heart rate of patients during orafter an operation.

BACKGROUND: Management of anticoagulant therapy in COVID-19 patients is critical. Low-molecular-weight heparin (LMWH) thromboprophylaxis is already recommended, and anti-Factor Xa (anti-FXa) monitoring has been used to titrate LMWH doses. METHODS: Through a cross-sectional study, we evaluated anti-FXa activity in patients admitted to the ICU, receiving intermediate dose (30, 40, 50 mg, subcutaneously [SC], twice daily) or therapeutic dose (1 mg/kg, SC, Q12h) of enoxaparin to find whether the patients in these two groups achieved anti-FXa levels in the accepted thromboprophylaxis range. RESULTS: The occurrence of deep vein thrombosis was 26% in the therapeutic-dose group and 17% in the intermediate-dose group. D-dimer values were nearly 3.5-fold higher in those who received a therapeutic dose of anticoagulants than in those who received intermediate-dose thromboprophylaxis. Patients in the therapeutic-dose group had significantly higher IL-6 levels (p ≤ 0.001). More than one-third of the patients in the therapeutic-dose group (n = 8; 42.18%) and approximately half of the patients in the intermediate-dose group (n = 12; 52.2%) achieved the target range level of anti-FXa. Patients who received therapeutic doses were more likely to have anti-FXa levels above the expected range (47.4 vs 13% in the intermediate-dose group; p < 0.05). CONCLUSION: Therapeutic dose of enoxaparin in critically ill COVID-19-infected patients did not reduce the incidence of thromboembolic events and, on the other hand, may predispose these patients to increased risk of bleeding by increasing anti-FXa activity above the desired level. Administration of intermediate-dose thromboprophylaxis is suggested to achieve anti-FXa levels in the accepted thromboprophylaxis range.

Background: The erector spinae plane (ESP) block is a novel approach to minimizing postoperative pain. We investigated the efficacy and side effects of the ultrasonography-guided bilateral ESP block in reducing pain in the first 24 hours after lumbar laminectomy. Materials and Methods: We conducted a single-blind (statistical analyst and those responsible for recording patient information postoperation were unaware of the study groups) randomized clinical trial on 50 patients aged 18 to 65 with American Society of Anesthesiology (ASA) class I or II physical status scheduled for lumbar laminectomy surgery at Shahid Chamran Hospital, Shiraz, Iran. Patients were randomly allocated to the ESP block (26 participants) or control (24 participants) group. A bilateral ESP block was administered to patients in the first group before general anesthesia, which was provided identically to both groups. The postoperative time to the first request of analgesia, pain score, total opioid use, side effects, and patient satisfaction were compared between the groups. Results: Compared with the control group, patients in the ESP block group had significantly more postoperative pain relief in the first hour and until 24 hours (P < 0.05). The total opioid consumption was lower in the ESP block group (P < 0.001). However, the ESP block led to a higher rate of urinary retention (P = 0.008). Conclusion: The bilateral ESP block effectively reduces postoperative pain following lumbar laminectomy, minimizing the need for narcotics. Further research is needed to delineate ways to reduce urinary retention as its main complication. This trial is registered with IRCT20100127003213N6.
