Ultrasound and nerve stimulator guidance lumbar transforaminal epidural block for the treatment of patients with lumbosacral radicular pain.

Transforaminal epidural block (TEB) is a widely accepted technique and minimally invasive procedure for the treatment of lumbosacral radicular pain. This study aimed to evaluate the accuracy, efficacy, and safety of ultrasound and nerve stimulator guidance lumbar transforaminal epidural block (UNTEB) for the patients with unilateral lower lumbar radicular pain. The accuracy of this method was evaluated by fluoroscopy. Using UNTEB via axial and the in-plane approach technique was performed in 42 segments of 25 patients who presented with lumbosacral radicular pain to lower extremities. The contrast medium was injected to evaluate the needle tip at the intervertebral foramen under fluoroscopic guidance. The numerical rating scale was used to assess pain before and after treatment. The success ratio of UNTEB in L3/L4 level was 100%, in L4/L5 was 95.4% and in L5/S1 was 100%. The numerical rating scale (NRS) for lumbosacral radicular pain improved from a mean from 7.8 to 2.8 1 day after procedure (p = 0.01) and from a mean from 7.8 to 2.4 1 week after UNTEB (p = 0.01). None of our subjects experienced any complications during and after the procedure. UNTEB with fluoroscopic validation is an accurate, effective, and safe method for short-term pain relief of the patients with unilateral lumbosacral radicular pain.

Comparing topical administration of lidocaine alone and in combination with alfentanil in children undergoing bronchoscopy.

INTRODUCTION: Airway surgery and endoscopy in pediatric patients are always associated with challenges in anesthesia management. Deep anesthesia is required for preventing patient bucking during the procedure but patient breath should be maintained; in this regard, a combination of general and topical anesthesia can be beneficial. There is also evidence of the peripheral effects of opioids. The main objective of this study is to compare using lidocaine topically alone and combined with alfentanil opioids with respect to the central effects of opioids. METHODS: In this study, 40 ASA class I and II children, aged 1-6 years, who were candidates for flexible diagnostic bronchoscopy were divided into two groups through block randomization using the random number table after obtaining parents' consent in complete health conditions. In this clinical trial, for collecting the data a special data collection form was used at the bedside of patients undergoing bronchoscopy at Pediatric Medical Center in 2017. Data including demographic information (age, weight, gender), duration of anesthesia, blood pressure before and after drug administration, duration of bronchoscopy, and recovery time were recorded in a form. FINDINGS: In terms of demographic variables, there were not any significant differences between the two studied groups, indicating that the groups were matched and randomized appropriately. Although there were not any significant differences between the two groups of using lidocaine alone and in combination with alfentanil in other variables, in the recovery time a significant difference was observed between the two groups, with a mean of 13.05 min in the lidocaine group and 18.75 min in the lidocaine combined with alfentanil group. CONCLUSION: Topical administration of opioid with lidocaine through bronchoscopy had no impact on blood pressure, heart rate, anesthesia duration, and the frequency of perioperative complications.

Comparison of the Laryngoscopic View using Macintosh and Miller Blades in Children Less than Four Years Old.

This study aimed to compare Miller and Macintosh laryngoscopes in zero to 4-year-old children. A total of 72 children with a score of I and II, according to the American Society of Anesthesiologists (ASA) physical status classification, who were candidates for elective surgery with general anesthesia and tracheal intubation were enrolled in the study. The children were divided into two equal groups (36 persons) according to used laryngoscope: Miller laryngoscope (group 1) and Macintosh laryngoscope (group 2). Observations and all laryngoscopies were performed by a single experienced anesthesiologist. Heart rate, systolic blood pressure, non-invasive arterial blood pressure, and hemoglobin saturation were measured and recorded. The number of endotracheal intubation attempts and complications were also recorded for both groups. In terms of gender, the first group consisted of 88.9% boys and 11.1% girls, and the second group consisted of 66.6% boys and 33.3% girls (p-value=0.05). The mean age was 16.7 months in the first group and 17.7 months in the second group (p-value=0.5). The mean weight of the children was 16988.5 g and 16300 g in the Miller and Macintosh groups, respectively (p-value=0.9). Regarding the Cormack-Lehane classification system, 5 patients were classified as grade 1 (13.9%), 14 patients as grade 2 (38.9%), 15 patients as grade 3 (41.7%), and 2 patients as grade 4 (5.6%) in the Macintosh group. In contrast, in the Miller group, 5 patients were classified as grade 1 (13.9%), 27 patients as grade 2 (75%), and 4 patients as grade 3 (11.1%) (p-value=0.004). These results can provide more data about the tracheal intubation method with the Macintosh and Miller laryngoscopes, the ease of intubation, and the best laryngoscopic view with each blade.

Anesthetic Management in a Child With Niemann-Pick Disease.

Niemann-Pick is a lipid storage disease that results from a lysosomal enzyme deficiency (sphingomyelinase). It has different presentations, and it may affect various organs such as the central nervous system, kidney, liver, and spleen. Due to the complexity of the disease, careful perianesthetic management is necessary in order to reduce the risks and sequels. As there is little evidence available in the literature regarding the anesthetic implications of such patients, in this case report we describe the anesthetic management of a two-year-old female with Niemann-Pick disease.

Ketamine or atropine: which one better prevents oculocardiac reflex during eye surgery? A prospective randomized clinical trial.

Profound bradycardia during eye surgery is a potentially serious event. In clinical practice oculo-cardiac reflex (OCR) is most often encountered during squint surgery. The objective of this study was to assess the occurrence of OCR and prove the effect of ketamine as an induction drug and anticholinergic premedication (atropine) to prevent OCR. This study comprised 90 patients (aged 4-10 years) operated for squint surgery under general anesthesia. Patients were divided into three groups. Using block randomization, each patient enrolled in one of the three groups based on organized random table prepared by statistician. Group K received ketamine as an induction drug, Group A was premedicated with intravenous injection of atropine and Group C did not receive any premedication. Patients were monitored during operation for any bradycardia or dysrhythmias. The observed data showed occurrence of 63% OCR in Group C as compared to 43% in group A and only 20% in Group K. Current study showed that induction with ketamine in the patients of squint surgery under general anesthesia definitely obtunds OCR and prevents any untoward effects of dysrhythmias during eye surgery.
