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.

Orofaciodigital syndrome type II (Mohr syndrome): a case report.

BACKGROUND: Orofacial digital syndrome is a rare genetic disorder with oral cavity, facial and digits anomalies. Orofacial digital syndrome type II, also called the "Mohr syndrome" is a very rare subtype that has been reported scarcely in Asia especially in Japanese patients. CASE PRESENTATION: The case is an Iranian 5-year old girl who had been admitted for orthopedic surgery. She surprisingly had pre and postaxial polydactyly of all the four limbs concurrent with syndromic face and most of the features of Orofaciodigital syndrome type II. CONCLUSION: Mohr syndrome, anesthesia and surgical considerations are discussed in this case report. It is recommended to consider these considerations and the possibility of OFDS in every child with pre and postaxial polydactyly of the four limbs and to try to distinguish type II from other types of ODFS.

Endotracheal intubation in patients with difficult airway: using laryngeal mask airway with bougie versus video laryngoscopy.

Airway management is essential for safe anesthesia and endotracheal intubation is the most important procedure by which critically ill patients can be better managed, especially if done quickly and successfully. This study aimed to compare the techniques of intubation through laryngeal mask airway (LMA) using a bougie versus video laryngoscopy (VL) regarding to intubation success and the quality of intubation indices in patients with difficult airways. This randomized clinical trial was performed on 96 patients aged 16-76 years with Mallampati class 3 or 4 who underwent elective surgery. Once the demographics were recorded, patients were randomly divided into two groups and the first group intubated with VL, and the second group intubated through laryngeal mask using a bougie. Then vital signs, arterial oxygen saturation, the time required for successful intubation, and ease of intubation were recorded. Here t-tests, chi-square, Fisher exact tests, and analysis of variance for repeated measurement were used to analyze the data in SPSS software. The overall success rates of intubation in VL and LMA groups were 46 (96%) and 44 (92%), respectively. The mean duration of intubation for the LMA and VL groups was 18.70 ± 6.73 and 14.21 ± 4.14 seconds, respectively (P < 0.001). Moreover, visual analogue scale score for pain in throat was significantly lower in VL group than LMA (1.65 ± 0.76 vs. 1.33 ± 0.52). Moreover, easy intubation in bougie group was 50%, while the easy intubation in VL was 73% (P = 0.023). In addition, incidence of cough was 31% in the LMA with bougie group and 9% in VL group (P = 0.005). The VL technique is an easier method and has a shorter intubation time than LMA using bougie, and causes a lower incidence of coughing, laryngospasm in patients that need intubation. Moreover, cough and discomfort in the throat tend to be less in VL, and the LMA could be used as replacement of VL in hard situations.

Comparing the analgesic effect of intranasal with intravenous ketamine in isolated orthopedic trauma: A randomized clinical trial.

OBJECTIVES: Ketamine is commonly used in anesthetic and sedation before surgical procedures and acts as an analgesic in smaller doses. The aim of this study was to assess the effects of intranasal (IN) ketamine in patients with moderate to severe limb trauma (visual analog scale (VAS) > 60 mm). METHODS: In a triple-blind randomized controlled clinical trial; 154 patients with isolated orthopedic trauma and visual analog scale (VAS) ≥60 mm were included on the basis of inclusion and exclusion criteria. Patients were divided into two groups of ketamine-IN (0.4 mg/kg IN ketamine and an equal volume of placebo saline intravenously (IV)) and ketamine-IV (0.2 mg/kg ketamine IV with 0.5 ml saline IN) on the basis of balanced block randomization method. At 5, 10, 20, and 30 min, patients were assessed for VAS measurement and adverse events. Repeated measure ANOVA, independent t-test and chi square test were employed. The level of statistical significance was considered to be less than 0.05. RESULTS: Mean VAS in IN ketamine and IV group at minute 30 was 31.50 ± 13.40 and 29.35 ± 11.73, respectively. At minute 30, 31 patients (20.39%) required a low-dose of morphine as rescue analgesia (P = 0.427). The results showed that mean change score of VAS (difference of time 0 and time 30) in IN ketamine and IV ketamine VAS were 43.8 (95% confidence interval: 41.1-46.5) and 46.4 (95% confidence interval: 42.8-50.1) and there is no difference between two groups in case of score change of VAS (P = 0.245). Adverse events in nasal and intravenous ketamine in both groups were mild and transient. CONCLUSION: IN ketamine is associated with few side effects and appropriate analgesic effects in isolated orthopedic trauma patients, and it may be used in cases where there is no need for venipuncture of peripheral vessels, especially in crowded EDs.
