Anesthesia for a Child with Congenital Long QT Syndrome, a Case Report and Literature Review.

Long QT syndrome is an inherited disorder of the heart's electrical activity that may also be associated with malignant arrhythmia and cause sudden death. In addition to this inherited condition, several commonly used anesthetic drugs can prolong the QT interval. We present here a 17-month-old male patient who underwent general anesthesia for a cochlear implant. No cardiac arrhythmia was observed in the patient, whose muscle relaxant effect was reversed using sugammadex. The application of intravenous anesthetics was preferred to maintain anesthesia for this patient and was safely applied.

Analgesic efficacy of ultrasound guided paravertebral block in percutaneous nephrolithotomy patients: a randomized controlled clinical study.

BACKGROUND: Paravertabral blocks (PVB) are in use to adequately manage pain arising from a variety of operations on the thorax, abdomen or pelvis. PVB is straightforward, efficacious in operations performed. This study was undertaken to evaluate how efficacious ultrasound-guided thoracic paravertebral block is when used in patients undergoing percutaneous nephrolithotomy (PCN). METHODS: A total of 44 patients, falling in categories I to III of the American Society of Anesthesiologists, and aged between 18 and 65 years, who were scheduled for PCN, were randomly distributed into two groups. The anaesthetic intervention group (PVB) contained 22 individuals, who were injected at level T8-T9 with 20 mL 0.25% bupivacaine as a single administration. In the control group C, also containing 22 individuals, the intervention was not carried out. The groups were compared after PCN in terms of opioid use, pain score, opioid adverse effects profile and the need for supplemental analgesia. RESULTS: Visual analogue scale pain scores whilst at rest or moving were lower at the level of statistical significance in the PVB group compared to controls at 2 and 4 h post-surgery. At 6 and 8 h post-surgery, the control group had a lower VAS score when moving, and this result reached statistical significance (p < 0.05). The controls used more opioid relief than the PVB group and had lower scores for satisfaction (p < 0.05). CONCLUSION: Ultrasound-guided PVB using bupivacaine and an in-plane technique provides effective analgesia in PNL. It is associated with high scores on patient satisfaction and minimal complications.

Anesthetic management of a patient with Bardet-Biedl syndrome undergoing renal transplantation: A case report.

INTRODUCTION: Bardet-Biedl syndrome, which compromises airway management and the cardiovascular and renal systems, is a rare ciliopathic syndrome characterized by multisystem involvement and varying genetic etiologies and clinical manifestations. PATIENT CONCERNS: A 13-year-old female patient had a history of chronic renal failure, hypothyroidism, mental retardation, hypogonadotropic hypogonadism, obesity, and retinitis pigmentosa and was undergoing 4-hour hemodialysis 3 days a week. DIAGNOSIS: We diagnosed Bardet-Biedl syndrome based on the results of genetic tests. INTERVENTIONS: We performed renal transplantation under general anesthesia while considering the perioperative risks of airway obstruction and hypothermia. OUTCOMES: Multidisciplinary preoperative evaluation is crucial to avoid perioperative complications. The risk of an obstructed airway should be considered. Hypothyroidism is a rare consequence of Bardet-Biedl syndrome. Rocuronium and sugammadex are safe for anesthetic management during renal transplantation to address Bardet-Biedl syndrome. CONCLUSION: Safe anesthetic management can be achieved with the rigorous preoperative assessment of perioperative complications.

Evaluation of the systemic antiinflammatory effects of levosimendan in an experimental blunt thoracic trauma model.

BACKGROUND: Blunt thoracic injury often leads to pulmonary contusion and the development of acute respiratory distress syndrome, which carries a high risk of morbidity and mortality, originating from the local and systemic inflammatory states. This study aimed to investigate the local and systemic antiinflammatory effects of levosimendan in rat models of blunt chest trauma. METHODS: A total of 32 Wistar albino rats were randomly assigned to one of the following four groups: control, sham, low-dose levosimendan (LDL) (5 µg/kg loading dose for 10 min and 0.05 µg/kg/min intravenous infusion), and high-dose levosimendan (HDL) (10 µg/kg loading dose for 10 min and 0.1 µg/kg/min intravenous infusion). Blunt chest trauma was induced, and after 6 h, the contused pulmonary tissues were histopathologically and immunohistopathologically evaluated, serum TNF-α, IL-1ß, IL-6, and NO levels were biochemically evaluated. RESULTS: The mean arterial pressure was low throughout the experiment in the LDL and HDL groups, with no statistically difference between the groups. Levosimendan reduced the alveolar congestion and hemorrhage, which developed after inducing trauma. Neutrophil infiltration to the damaged pulmonary tissue was also reduced in both the LDL and HDL groups. In rats in which pulmonary contusion (PC) was observed, increased activation of nuclear factor kappa B was observed in the pulmonary tissue, and levosimendan did not reduce this activation. Both high and low doses of levosimendan reduced serum IL-1ß levels, and high doses of levosimendan reduced IL-6 and NO levels. TNF-α levels were not reduced. CONCLUSION: In conclusion, the results showed that in a rat model of PC, the experimental agent levosimendan could reduce neutrophil cell infiltration to damaged pulmonary tissues and the systemic expressions of some cytokines (IL-1ß, IL-6, and NO), thereby partially reducing and/or correcting pulmonary damage. Systemic inflammatory response that occurs after trauma could also be reduced.

Preoperative and post-operative sleep quality evaluation in rotator cuff tear patients.

PURPOSE: The aim of this study was to examine the potential relationship between subjective sleep quality and degree of pain in patients with rotator cuff repair. METHODS: Thirty-one patients who underwent rotator cuff repair prospectively completed the Pittsburgh Sleep Quality Index, the Western Ontario Rotator Cuff Index, and the Constant and Murley shoulder scores before surgery and at 6 months after surgery. Preoperative demographic, clinical, and radiologic parameters were also evaluated. RESULTS: The study analysed 31 patients with a median age of 61 years. There was a significant difference preoperatively versus post-operatively in terms of all PSQI global scores and subdivisions (p < 0.001). A statistically significant improvement was determined by the Western Ontario Rotator Cuff Scale and the Constant and Murley shoulder scores (p Ë‚ 0.001). CONCLUSION: Sleep disorders are commonly seen in patients with rotator cuff tear, and after repair, there is an increase in the quality of sleep with a parallel improvement in shoulder functions. However, no statistically significant correlation was determined between arthroscopic procedures and the size of the tear and sleep quality. It is suggested that rotator cuff tear repair improves the quality of sleep and the quality of life. LEVEL OF EVIDENCE: IV.

Risk Factors for Colistin-Associated Acute Kidney Injury: A Multicenter Study from Turkey.

The aim of this study was to investigate the incidence of acute kidney injury (AKI) and risk factors due to colistin use in patients infected with multidrug-resistant pathogens. This multicenter, retrospective, observational study was conducted in Turkey, at 5 different research and university hospitals. Cox regression analyses were performed, to determine independent predictors of AKI. From April 2012 to July 2014, a total of 216 patients aged between 18-94 years, treated with colistimethate sodium (CMS) were included in the study. The mean age of the patients was 60.3 ± 20.1 years. The overall incidence of AKI was 34.3% (74/216) at any time during treatment. Concomitant use of loop diuretics, baseline creatinine level, and CMS dosage were independently associated with AKI. According to our results, patients with higher baseline creatinine levels, or patients who had to use concomitant loop diuretics may need to be monitored more closely, and dose adjustment should be done promptly. More comprehensive studies are, however, still needed to evaluate the efficacy of low-dose colistin since higher doses tend to increase the risk of AKI.

Unexpected difficult airway with hypogonadotropic hypogonadism.

BACKGROUND: A critical aspect of safe general anesthesia is providing adequate ventilation and oxygenation. Failed endotracheal intubation and inadequate ventilation with insufficient oxygenation may lead to serious complications, even death. Anesthesiologists rarely encounter unexpected difficult airway problems in daily routine. Management of an unexpectedly difficult airway consists of laryngeal mask ventilation, gum-elastic bougie and video laryngoscopy-assisted intubation. Gum-elastic bougie is the easiest and cheapest tool used in case of an unexpected difficult intubation occurring in the operating room. CASE: A 53-year-old male patient with hypogonadotropic hypogonadism presented as an unexpected difficult intubation after the induction of anesthesia. No pathological finding or predictor of difficult intubation was present. In addition, bag-mask ventilation was poor and inadequate. The patient was finally successfully intubated with a gum-elastic bougie. CONCLUSION: A difficult airway has been described in patients with a variety of endocrine disorders, including pituitary diseases, but not with hypogonadism. There may be an unrevealed relationship between hypogonadism and difficult airway. Gum-elastic bougie is still the most attainable and effective tool in the operation room in this situation.

The efficacy of intravenous paracetamol versus tramadol for postoperative analgesia after adenotonsillectomy in children.

STUDY OBJECTIVE: To evaluate the efficacy and the quality of recovery with intravenous (IV) paracetamol versus tramadol for postoperative analgesia after adenotonsillectomy in children. DESIGN: Prospective, randomized, double-blinded clinical trial. SETTING: Operating room and Postanesthesia Care Unit (PACU) of a university-affiliated hospital. PATIENTS: 64 ASA physical status I and II children, aged 6 to 16 years, scheduled for adenotonsillectomy. INTERVENTIONS: All patients were premedicated with oral midazolam 0.5 mg/kg 30 minutes before surgery. Patients were randomized to two groups following induction of general anesthesia. The paracetamol group (n = 32) received 15 mg/kg of IV paracetamol and the tramadol group (n = 32) received 1.0 mg/kg of IV tramadol. MEASUREMENTS: Modified Hannallah pain scores, emergence agitation, Aldrete scores, sedation scores, time to first administration of analgesic, heart rate, and mean arterial blood pressure were recorded for each patient. Data were recorded every 5 minutes for the first 30 minutes and every 10 minutes for the remaining 30 minutes in the PACU, then at 2, 3, 4, 5, 6, 8, 12, and 24 hours in the ward. The frequency of postoperative nausea and vomiting also was noted. Satisfaction of parents and nurses was determined on a 4-point scale at the end of the study. MAIN RESULTS: No significant demographic differences between groups were noted. No statistically significant difference was found in postoperative pain scores in either group. Agitation scores, Aldrete scores, sedation scores, and number of patients who received rescue analgesia and time to administration of rescue analgesia were similar in both groups. CONCLUSIONS: The IV formulation of paracetamol was associated with similar analgesic properties and early recovery to that of IV tramadol after adenotonsillectomy in children.
