BACKGROUND In search of an optimal drug for I-gel insertion, in our study, we have compared two group of drugs dexmedetomidine with propofol and fentanyl with propofol.
Objectives:To compare the effects of prophylactic ketamine and dexmedetomidine on postoperative bladder catheter-related discomfort/pain in patients undergoing cystoscopy.Methods:This prospective study was conducted on 75 American Society of Anesthesiologists (ASA) I-II patients between 18-75 years of age and undergoing cystoscopy between November 2011 and June 2012 at Hacettepe University Hospital, Ankara, Turkey. Patients were randomly assigned to one of the 3 groups to receive 1 µ/kg dexmedetomidine, 250 µ/kg intravenous ketamine, or normal saline. All patients were questioned regarding probe-related discomfort, patient satisfaction, and pain at the end of the operation 0 (t0) and 15 (t1), 60 (t2), 120 (t3), and 360 (t4) minutes postoperatively. Evaluations were performed in person at the post-anesthesia care unit, or in ambulatory surgery rooms, or by phone calls.Results:Pain incidence in the dexmedetomidine and ketamine groups (p=0.042) was significantly lower than that in the control group (p=0.044). The sedation scores recorded at t0 in the dexmedetomidine and ketamine groups (p=0.004) were significantly higher than that of the control group (p=0.017). Patient groups were similar regarding the rate of hallucinations experienced at t1, no patients experienced hallucinations at t2, t3, or t4. Significantly more patients experienced hallucinations at t0 in the ketamine group than in the dexmedetomidine group (p=0.034) and the control group (p=0.005).Conclusion:Dexmedetomidine and ketamine had similar analgesic effects in preventing catheter-related pain; however, dexmedetomidine had a more acceptable side effect profile. To identify the optimal doses of dexmedetomidine and ketamine, more large-scale interventional studies are needed.
INTRODUCTION: Cleft lip/palate (CLCP) patients might need postoperative care in Intensive Care Unit (ICU) due to several reasons like difficult airway management, associated abnormalities and perioperative respiratory complications. Our aim was to evaluate the factors associated with difficult airway and need for postoperative ICU follow-up in CLCP patients operated in our institution. METHODS: CLCP patients followed in ICU after surgery between 2005-2013 were retrospectively reviewed. RESULTS: Twenty patients were included to the study. Ten had CLCP together, ten had isolated cleft palate. Difficult intubation was seen in 8 patients. Difficult mask ventilation was seen only in one patient with 22q11 deletion. All patients with difficult intubation had micrognathia. Nasal fiberoptic bronchoscopy was more commonly used in patients with difficult intubation. There was a statistically significant relationship between the presence of any systemic disease and difficult intubation. Main reasons for ICU follow-up were the need for close monitoring and airway related problems. DISCUSSION AND CONCLUSION: Difficult airway is a frequent problem in CLCP patients even in the absence of a diagnosed syndrome. Patients with difficult airway or risk of postoperative airway obstruction could be better followed in ICU during early postoperative period for rapid diagnosis and treatment of possible complications by experienced staff.
BackgroundIntra-articular local anaesthetics are widely used for providing postoperative analgesia and decreasing the need for opioids. Procaine has proven positive effects in carpal tunnel syndrome and chondromalacia patella. However, the effect of procaine on articular cartilage has not yet been studied. The aim of this study was to evaluate the effects of intra-articular procaine injection on the articular cartilage and the synovium.MethodsTwenty adult Sprague-Dawley rats were enrolled in the study. After providing anaesthesia and aseptic conditions, 0.25 ml of 10% procaine was injected to the right knee joint, and 0.25 ml of normal saline (as control group) was injected to the left knee joint. Knee joint samples were obtained from four rats in each group after appropriate euthanasia on days 1, 2, 7, 14 and 21. The histological sections of the articular and periarticular regions and the synovium were evaluated by two histologists, and inflammatory changes were graded according to a five-point scale in a blinded manner. The apoptosis of chondrocytes was determined by the caspase-3 indirect immunoperoxidase method.ResultsThere were no significant differences in inflammation between procaine and saline groups at any of the time intervals. Slight inflammatory infiltration due to injection was seen in both groups on the 1st day. Haemorrhage was observed in both groups at days 1 and 2, and the difference between groups was not found to be significant. No significant difference was detected in the percentage of apoptotic chondrocytes between groups at any of the time intervals.ConclusionsInjection of procaine seems safe to use intra-articularly based on this in vivo study on rat knee cartilage. However, further studies investigating both the analgesic and histopathological effects of procaine on damaged articular cartilage and synovium models are needed.
Patients diagnosed with abdominal pain related to mitochondrial neurogastrointestinal encephalopathy (MNGIE) may benefit from splanchnic nerve blockade. MNGIE, varying in age of onset and rate of progression, is caused by loss of function mutation in thymidine phosphorylase gene. Gastrointestinal dysmotility, pseudo-obstruction and demyelinating sensorimotor peripheral neuropathy (stocking-glove sensory loss, absent tendon reflexes, distal limb weakness, and wasting) are the most prominent manifestations. Patients usually die in early adulthood (mean 37.6 years; range 26-58 years). We report a case of an 18-year-old patient with MNGIE. Our patient's abdominal pain was relieved after splanchnic nerve blockade.
Background: Foreign body aspiration (FBA) is a serious life-threatening condition in childhood. ''Baby-led weaning (BLW)'' is a popular method in which the babies are encouraged to self-feed to gain oral motor abilities. The role of BLW in FBA is controversial. A retrospective study was performed to evaluate the results of FBA in infants (<1 year of age) and its relation to the feeding method. Materials and Methods: Children who underwent bronchoscopy for FBA for the past 10 years were included. Infants (<1 year of age) were evaluated for age, gender, clinical findings, and the results of bronchoscopy. The type of feeding, including self-feeding or caregiver-assisted feeding, was noted. Results: The medical records of 826 patients who underwent bronchoscopy were evaluated. FBA was noted in 50.2% (n = 417) of cases. Only 9.07% (n = 75) of patients were <1 year of age and 67% (n = 50) of them had a foreign body according to the bronchoscopy. The mean age was 9 months (5-12 months) and 36% of them were male. When the feeding characteristics of patients were surveyed, 80% of cases aspirated when self-feeding and 14% aspirated during caregiver-assisted feeding. Conclusions: Self-feeding to promote oral motor function may cause FBA in infants. Emergent bronchoscopy is more common in infants and reveals the aspiration of foods that cannot be consumed safely in this age group.
ObjectivesThe age-based Cole formula has been employed for the estimation of endotracheal tube (ETT) size due to its ease of use, but may not appropriately consider growth rates among children. Child growth is assessed by calculating the body surface area (BSA). The association between the outer diameter of an appropriate uncuffed-endotrachealtube (ETT-OD) and the BSA values of patients at 24–96 months of age was our primary outcome.MethodsCole formula, BSA, age, height, weight and ultrasound measurement of subglottic-transverse-diameter were evaluated for correlations with correct uncuffed ETT-OD. The Cole formula, BSA, and ultrasound measurements were analyzed for estimation rates in all patients and age subgroups. The maximum allowed error for the estimation of ETT-OD was ≤0.3 mm. Patients’ tracheas were intubated with tubes chosen by Cole formula and correct ETT-OD values were determined using leak test. ETT exchange rates were recorded.ResultsOne-hundred twenty-seven patients were analyzed for the determination of estimation rates. Thirteen patients aged ≥72 months were intubated with cuffed ETT-OD of 8.4 mm and were accepted to need uncuffed ETT-OD >8.4 mm in order to be included in estimation rates, but excluded from correlations for size analysis. One-hundred fourteen patients were analyzed for correlations between correct ETT-OD (determined by the leak test) and outcome parameters. Cole formula, ultrasonography, and BSA had similar correct estimation rates. All three parameters had higher underestimation rates as age increased.Conclusion.The Cole formula, BSA, and ultrasonography had similar estimation rates in patients aged ≥24 to ≤96 months. BSA had a correct estimation rate of 40.2% and may not be reliable in clinical practice to predict uncuffedETT-size.
Background: The commonly preferred right internal jugular vein was investigated in terms of its dimensions, the relationship between its dimensions and anthropometric measures, and the outcomes of its cannulation in infants. Data regarding its position with respect to the carotid artery indicated anatomical variation. Aim: The aim of this study was to share our observations pertaining to the anatomy and position of the right internal jugular vein with respect to carotid artery using ultrasound and our experience with ultrasound-guided right internal jugular vein access in neonates and small infants. Materials and methods: A total of 25 neonates and small infants (<4000 g) undergoing ultrasound-guided central venous cannulation via right internal jugular vein within a 6-month period were included. Ultrasound-guided anatomical evaluation of the vein was used to obtain the transverse and anteroposterior diameters, the depth from skin and the position with respect to the carotid artery. Real-time ultrasound-guided central cannulation success rates and complication rates were also obtained. The patients were divided into two groups with respect to their weight in order to compare both the position and the dimensions of right internal jugular vein and cannulation performance in infants weighing <2500 g and ⩾2500 g. Results: The position was lateral to the carotid artery in 84% of all infants and similar in both groups. The first-attempt success rates of cannulation were similar (70% vs 73.3%) in both groups, with an overall success rate of 88%. Conclusion: Right internal jugular vein revealed a varying position with respect to carotid artery with a higher rate of lateral position. The presence of such anatomical variation requires ultrasonographic evaluation prior to interventions and real-time guidance during interventions involving right internal jugular vein.
