Context:
Diabetes is one of the most common causes of neuropathy. Morbidity and mortality increase in patients suffering from diabetic polyneuropathy and are experienced by approximately 10 to 54% of diabetic patients. Severe pain, loss of sensation, increased risk of ulceration, andevenamputationare the complications of diabetic neuropathy. Intradermal injection of botulinum toxin type-A (BTX-A) is a relatively novel method for the treatment of painful diabetic neuropathy. This method is becoming popular considering its acceptable and long-lasting pain control and minimal systemic side effects.
MethodsThis narrative systematic review aimed to evaluate the effectiveness of intradermal BTX-A injection on painful diabetic neuropathy. The queried databases included PubMed, EMBASE, Cochrane Central Register of Controlled Trials (CENTRAL), ClinicalTrials.gov,Web of Science, Scopus, and Google Scholar. The final search was performed in February 2022, and no time limits were set for the search. All the relevant clinical trials were included. The inclusion criteria and search strategy were set as follows: type of study: randomized clinical trial (RCT) or other types of interventional studies; publication date: all published studies until February 22, 2022; sample size: no restrictions; outcomes: effect on diabetic neuropathy pain; quality: earning a minimum acceptable score based on critical appraisal; and language: English. The searches and article screening were performed by two independent reviewers to minimize the possibility of bias. In case of disagreement about a study, the comments of an expert (as a third person) were used to resolve the ambiguity.
ResultsIn a review of 4 RCTs and 1 case-control study on the effectiveness of BTX-A in reducing the pain of diabetic neuropathy, 273 patients were evaluated in total. The lowest and highest number of subjects was 18 and 141. The sex distribution included 43.22% men and 56.77% women, all of whom were 47.8 to 74.8 years old. Three studies were conducted in Iran, Taiwan, and Egypt. The results of this reviewshowedsignificantimprovementin pain reduction, e.g., basedonthe visual analog scale (VAS)andNeuropathic Pain Scale (NPS). A few studies evaluated sleep and psychosocial complications, and their results indicated a statistically significant improvement in the Pittsburgh Sleep Quality Index (PSQI) and the physical subscale of the 36-Item Short Form Survey (SF-36).
ConclusionsThe results of this systematic review demonstrated that intradermal injection of BTX-A causes significant and long-term (up to 12 weeks) improvement in diabetic neuropathy pain. The improvement in sleep and mental or physical functions was not consistent, and no conclusive result could be reached.

Pregnant women’s knowledge about labor analgesia and the acceptance rate of this method are still undesirable in developing countries.
ObjectivesThis study aimed to examine pregnant women’s knowledge, attitude, and acceptance of painless labor.
MethodsThe present observational study was conducted in a referral university hospital in Northern Iran from September 2022 to April 2023. Eligible women were interviewed; the data were analyzed in SPSS v. 22 and expressed in numbers and percentages. A P-value < 0.05 was considered significant.
ResultsThe data from 369 eligible women with an average age of 30.39 ± 5.42 years were analyzed. Of these women, 7.6% had minimal information about labor analgesia, and 92.4% declared they were almost aware of the procedure. Only 6 women (1.8%) believed that the anesthesiologists were responsible for performing labor analgesia, while 218 (63.9%) considered it the duty of obstetricians-gynecologists. Besides, 294 women (86.2%) requested this method, and 259 (76%) were ready to pay for it. Moreover, 166(48.7%) had no fear of the procedure. Nonpharmacologic methods were the first choice for 164 (48.1%), while Entonox was the last choice for 26 (7.6%). A significant association was observed between maternal level of education and willingness to pay for painless delivery (P = 0.006), knowledge of who performs it (P = 0.015), requesting a painless delivery (P = 0.0001), options related to the preferred method for painless delivery (P = 0.001), and being ready to pay for a painless delivery service (P = 0.0001).
ConclusionsDespite the poor maternal knowledge regarding the process of painless labor, the majority of the women requested the method and were ready to pay for it. These promising findings encourage the application of practical strategies to remove barriers.

Unwanted postoperative hypothermia is an unpleasant event that can cause various complications.
ObjectivesAs this serious complication and its provoking causes have not been investigated sufficiently, this study was designed and conducted to determine the prevalence of hypothermia and its associated factors in the post-anesthesia care unit after elective surgery.
MethodsFour hundred patients undergoing elective surgeries were enrolled in the present cross-sectional research after termination of surgery and at the time of arrival at the post-anesthesia care unit of Poursina Public University Hospital. The tympanic membrane temperature was measured and recorded at the time of arrival at the post-anesthesia care unit and every 30 minutes after arrival. The required data were collected in a researcher-made checklist and analyzed after entering the SPSS software version 25.
ResultsConsidering the 5% error, it can be said that the prevalence of hypothermia in patients undergoing elective surgery ranges from 20 to 28% at the time of arrival at the post-anesthesia care unit and 18.5 to 26% 30 minutes after arrival.
ConclusionsMore than a quarter of patients experienced hypothermia following elective surgery. Therefore, appropriate treatment and control measures are necessary to manage this complication, particularly in patients with predisposing risk factors and comorbidities.

Spinal anesthesia (SA) for the surgical management of chronic anal fissures is favored by surgeons as it provides an early return to daily activities; however, the agents applied for SA to achieve the best outcomes with minimized adverse effects are a matter of debate.
ObjectivesThis study aimed to assess the utility of Marcaine versus meperidine for SA induction of anoderm surgery.
MethodsThis randomized clinical trial (RCT) was conducted on 138 patients with chronic anal fissures who were candidates for surgical management in 2020. The patients were randomly assigned to two groups of SA using 2.5 mL of hyperbaric Marcaine 0.5% (n=69) or 1mg/kgof meperidine (n=69). Pain severity (measured via Numerical Rating Scale (NRS)), anal sphincter tonemanometry (measured at baseline and the end of the sphincterotomy), and drug-related adverse effects were compared between the groups.
ResultsBoth agents led to significant pain relief within 24 hours after SA (P < 0.05); nevertheless, pain severity was remarkably lower in meperidine-treated patients in different measurements performed during the first 24 hours after SA (P < 0.05). The sphincteric tone significantly decreased in both groups (P < 0.001), while the postoperative tone was significantly less in the Marcaine-treated patients (65.22 ± 3.02 versus 46.04 ± 1.97, P < 0.001). The two groups did not differ regarding the adverse effects (P > 0.05).
ConclusionsMeperidine for SA in anal fissure surgical management was relatively superior to Marcaine, as postoperative pain control was remarkably better achieved with meperidine. However, anal sphincter tone reached a normal range in Marcaine-treated cases, and the average tone in those anesthetized with meperidine was slightly above the normal limits.

Depression is a prevalent mental disorder affecting more than 300 million people of all ages globally. Despite being the first-line treatment for depression, antidepressant medications are only effective for 60% - 70% of patients. Electroconvulsive therapy (ECT) is an effective treatment for severe cases, although it can result in short-term side effects.
ObjectivesThis study aimed to compare the effectiveness of remifentanil, dexmedetomidine, and metoral as premedications for ECT in patients with major depressive disorder (MDD).
MethodsIn this prospective double-blinded randomized controlled clinical trial, a total of 120 MDD patients aged 18 - 60 were included. They were randomly assigned to receive remifentanil, dexmedetomidine, or metoral in combination with thiopental before ECT. Hemodynamic responses (mean arterial blood pressure, pulse rate, arterial blood oxygen saturation), seizure duration, recovery time, agitation scores, and patient satisfaction scores (reverse coded) were measured and compared.
ResultsDexmedetomidineexhibited superiorhemodynamiccontrol with lowermeanarterial blood pressure (P< 0.001)andpulse rate (P < 0.001) than remifentanil and metoral. Patients receiving dexmedetomidine or remifentanil showed reduced agitation (P < 0.001) and better satisfaction than the metoral group (P < 0.001). Remifentanil displayed intermediate outcomes, while metoral exhibited the least favorable results. Seizure duration was not significantly different between the dexmedetomidine and remifentanil groups (P = 0.843).
ConclusionsDexmedetomidine is considered the most satisfactory group due to the better control of blood pressure, heart rate, and agitation and better patient satisfaction despite the longer recovery time.

Perioperative pain management strategies in the elderly undergoing hip arthroplasty need special and safe preemptive care.
ObjectivesThe primary aim of this study was to compare the analgesic effects of preemptive ultrasound-guided pericapsular nerve group (PENG) block and lumbar erector spinae plane block (L-ESPB) in the elderly undergoing hip arthroplasty. The time to the first postoperative rescue analgesiawasmeasured. The secondaryaimwasto assess the ease of spinal positioning (EOSP), onset of sensory block, block performance time, and patient satisfaction.
MethodsBefore positioning for spinal anesthesia, 69 elderly patients undergoing hip arthroplasty were randomized into three groups (n = 23 per group). The first intervention group received ultrasound-guided PENG block with 20 mL bupivacaine 0.25%; the second intervention group received ultrasound-guided L-ESPB using the same dose of bupivacaine. In the control group, patients received spinal anesthesia without any block.
ResultsThe time to first postoperative rescue analgesic (morphine) was significantly prolonged in the PENG group (13.3 ± 3.5 h) compared to the L-ESPB (9.5 ± 2.3 h) and control (2.6 ± 0.4 h) groups. The EOSP score was significantly higher in the PENG group compared to the L-ESPB and control groups (P < 0.001). The block performance time and oneset of the sensory block were significantly shorter in the PENG group compared to the L-ESPB group. The highest patient satisfaction scores were observed in the PENG group.
ConclusionsPreemptive pericapsular nerve group block postponed the need for postoperative analgesia and eased spinal positioning compared to L-ESPB in the elderly undergoing hip arthroplasty.

The pain experienced following supratentorial brain surgery is usually defined as moderate to severe. Therefore, pain-management approaches, including narcotics, are an integral part of treatment regimens that cause respiratory complications or seizures, and reducing this pain level and increasing patient satisfaction is vital.
MethodsThis randomized, double-blind clinical trial study to evaluate the pain level and satisfaction in patients undergoing surgery for supratentorial brain neoplasms was performed on two groups with a sample size of 50 patients. In group I, after removal of the brain lesion (at the beginning of dura closure), 400 mg of ibuprofen solution was infused intravenously over 30 minutes. In group II, morphine 0.07 mg/kg intravenously with 1000 mg paracetamol was infused over 30 minutes. After injecting ibuprofen and paracetamol morphine, the patient's pain level and satisfaction with the process were checked.
ResultsPatients' satisfaction score in the first 6 hours in the ibuprofen group was 1.67 ± 0.72, and in the other group was 2.27 ± 0.7, which was statistically different (P-value = 0.029). The mean of VAS in the first, second, third, and fourth hours was not statistically different. In the comparative analysis of the laboratory indicators of platelet function analysis in the two groups, none of the measured items had a significant difference between the two groups in the three measurement periods (P > 0.05).
ConclusionsAdministration of ibuprofen led to pain relief and patient satisfaction comparable to morphine and paracetamol, and after the surgery for supratentorial brain tumors, ibuprofen did not affect the patients’ blood clotting functions.

Peripheral nerve blocks (PNBs) are used in multiple surgical fields to provide a high level of regional pain relief with a favorable adverse effect profile. PNBs aim to decrease overall perioperative pain and lower systemic analgesic requirements. Short-acting anesthetic agents are commonly given as single-injection PNBs for pain relief, typically lasting less than 24 hours. Liposomal bupivacaine is a newer anesthetic formulation lasting up to 72 hours as a single-injection PNB and may allow patients to recover postoperatively with a lower need for opioid analgesics.
ObjectivesThis study investigates peri- and postoperative pain and opioid use in patients receiving a long-acting brachial plexus PNB for hand surgery.
MethodsA retrospective review of patients who underwent a long-acting PNB using liposomal bupivacaine in the brachial plexus for minor hand operations was performed between July 2020 and May 2023 in Florida, USA. Patients were administered a ten-question survey regarding perioperative pain levels, post-operative symptoms, patient satisfaction, postoperative opioid use, and postoperative non-opioid analgesics.
ResultsOne hundred three patients, including 21 males and 82 females with an average age of 68.3 ± 15.8 years, completed a survey (34.2% response rate). Patients reported a considerable reduction in pain from 7.9 ± 2.2 out of ten before the PNB to 1.6 ± 1.8 in the perioperative period, 4.3 ± 2.7 in postoperative days zero to three, and 3.8 ± 2.4 in postoperative days four and five. Nerve block effects lasted a mean of 2.2 ± 2.0 days and patients reported a high level of satisfaction regarding their pain management plan with a score of 9.4 ± 1.4 out of ten. 20.4% of patients were prescribed opioids and 41.7% used NSAIDs postoperatively.
ConclusionsLiposomal bupivacaine PNBs effectively reduced peri- and postoperative pain with pain relief lasting 2.2 ± 2.0 days. Patients were highly satisfied with their pain management and there was a low rate of postoperative opioid prescription. Given these results, long-acting PNBs have the potential to significantly improve patient satisfaction, reduce anesthesia use, and reduce postoperative opioid prescription.

Healthcare workers must wear masks throughout their shifts, especially those in operating rooms for long periods.
ObjectivesThis study evaluated the effects of wearing N95 masks on blood and cerebral oxygen saturation levels for three hours.
MethodsThe present case-control study enrolled 20 operating room workers wearing N95 masks. Their blood oxygen saturation (SaO2), end-tidal carbon dioxide partial pressure (PETCO2), and right- and left-sided cerebral oxygenation (rSO2) were measured in the beginning (0 h) and after wearing N95 masks for one and three hours.
ResultsWearing a mask affected PETCO2, rSO2, and pulse rate and caused fatigue and lightheadedness in some cases. The participants' mean PETCO2 increased significantly, from 32 mmHg before putting on a mask to 38 mmHg after wearing it for three hours (P < 0.05). No significant change was observed in the participants' mean rSO2, though changes in their rSO2 levels were recorded (P > 0.05).
ConclusionsWe showed evidence of changes in different physiology parameters due to using masks for 1 to 3 h. Notably, wearing an N95 mask increased end-tidal carbon dioxide partial pressure and decreased cerebral oxygen saturation in individual cases, not all cases.
