Sindrome di Brugada: durante anestesia generale il paziente è a rischio di sviluppare aritmie maligne?
The surgical patient with Brugada syndrome: a four-case clinical experience.
Brugada syndrome is characterized by a distinctive electrocardiographic pattern (right bundle branch block and ST segment elevation in precordial leads) and a high risk of cardiac arrest for malignant dysrhythmia. The genetic basis is a molecular defect of the cardiac sodium channel and the pattern of inheritance is autosomal dominant. Many factors during general anesthesia (medications, bradycardia, temperature changes) could precipitate malignant dysrhythmia in these patients. Because criteria to identify the surgical patient at high risk for developing malignant dysrhythmia are lacking, we can only speculate about the available studies on nonsurgical patients. We describe four patients during general anesthesia and propose intraoperative and postoperative monitoring (the first 36 h). ©2005 by the International Anesthesia Research Society
Robotic Assisted Surgery in Pediatric Gynecology: Promising Innovation in Mini Invasive Surgical Procedures
Robotic Assisted Surgery in Pediatric Gynecology: Promising Innovation in Mini Invasive Surgical Procedures
Study Objective: Robotic assisted surgery is not yet widely applied in the pediatric field. We report our initial experience regarding the feasibility, safety, benefits, and limitations of robot-assisted surgery in pediatric gynecological patients. Design: Descriptive, retrospective report of experience with pediatric gynecological patients over a period of 12 months. Setting: Department of Pediatric Surgery, IRCCS Policlinico San Matteo Foundation. Participants: Children and adolescents, with a surgical diagnosis of ovarian and/or tubal lesions. Main Outcome Measures: Robot assembly time and operative time, days of hospitalization, time to cessation of pain medication, complication rate, conversion rate to laparoscopic procedure and trocar insertion strategy. Results: Six children and adolescents (2.4-15 yrs), weighing 12-55 kg, underwent robotic assisted surgery for adnexal pathologies: 2 for ovarian cystectomy, 2 for oophorectomy, 1 for right oophorectomy and left salpingo-oophorectomy for gonadal disgenesis, 1 for exploration for suspected pelvic malformation. Mean operative time was 117.5 \ub1 34.9 minutes. Conversion to laparatomy was not necessary in any of the cases. No intra- or postoperative complications occurred. Conclusion: Initial results indicate that robotic assisted surgery is safely applicable in the pediatric gynecological population, although it is still premature to conclude that it provides better clinical outcomes than traditional laparoscopic surgery. Randomized, prospective, comparative studies will help characterize the advantages and disadvantages of this new technology in pediatric patients
Isolated colon ischemia with norovirus infection in preterm babies: a case series
Introduction. Norovirus infection with necrotizing enterocolitis has so far been reported as a specific tropism of the small bowel in premature newborns. Case presentation. Three cases of premature newborns presenting with extensive isolated colonic ischemia due to norovirus infection are reported.Patient 1 was a Caucasian girl with a gestational age of 29+2 weeks. She had sudden onset of abdominal distension on the 30th day of life. Radiological signs of colonic pneumatosis were present 48 hours before perforation and stool analysis was positive for norovirus. On the 34th day, free air was detected on plain abdominal X-ray. At laparotomy, stenosis, necrosis and perforations involved the whole colon. The patient underwent ileostomy. A large colon resection and ileosigmoid anastomosis were done 3 months later.Patient 2 was a Caucasian boy with a gestational age of 28+3 weeks. On the 19th day, bloody stools with abdominal distension appeared. Stool analysis resulted positive for norovirus. A plain abdominal X-ray showed distended bowel loops. Antibiotic treatment was started. On the 32nd day due to the progressive deterioration of clinical conditions and the appearance of colic pneumatosis, a laparotomy was performed. Severe damage of the transverse colon and multiple areas of necrosis were found. Terminal ileostomy was performed. Six months later surgery consisted of mid-transverse colon resection as far as the splenic flexure, colocolic anastomosis and closure of ileostomy.Patient 3 was a Caucasian boy with a gestational age of 30 weeks. On the 44th day bloody-mucous stools appeared and stool analysis was positive for norovirus infection. Even with institution of antibiotic therapy clinical abdominal radiologic signs of colonic pneumatosis of the upper right quadrant were found. At the 70th day an explorative laparotomy showed dilated bowel loops and stenotic right colon and ileostomy was mandatory. Partial colectomy was later necessary and ileocolic anastomosis was performed. Conclusion: We hypothesize that norovirus infection may be responsible for severe, distinctive colonic lesions, even in premature newborn infants
Pediatric laparoscopy and adaptive oxygenation and hemodynamic changes
Adaptive changes in oxygenation and hemodynamics are evaluated during pediatric laparoscopy. The children underwent laparoscopy (LAP Group, n=20) or open surgery (Open Group, n=10). Regional cerebral (rScO2) and peripheral oxygen saturation (SpO2), heart rate (HR), diastolic (DP) and systolic pressure (SP) were monitored at different intervals: basal (T0); anesthesia induction (T1); CO2PP insufflation (T2); surgery (T3); CO2PP cessation (T4); before extubation (T5). At T1, in both the LAP and Open groups significant changes in rScO2, DP and SP were recorded compared with T0; a decrease in SatO2 was also observed at T5. In the LAP group, at T2, changes in HR related to CO2PP pressure and in DP and SP related to IAP were noted; at T4, a SP change associated with CO2PP desufflation was recorded. Open group, at T3 and T5 showed lower rScO2 values compared with T1. Pneuperitoneum and anesthesia are influent to induce hemodynamics changes during laparoscopy
Five millimetre-instruments in paediatric robotic surgery: Advantages and shortcomings
The study was designed to assess the utility and controversies surrounding the usage of 5-mm instruments in paediatric robotic surgery. Adequate, delicate instruments for surgery in very narrow spaces are still lacking
Post-Operative Benefits of Animal-Assisted Therapy in Pediatric Surgery: A Randomised Study
<div><p>Background</p><p>Interest in animal-assisted therapy has been fuelled by studies supporting the many health benefits. The purpose of this study was to better understand the impact of an animal-assisted therapy program on children response to stress and pain in the immediate post-surgical period.</p><p>Patients and Methods</p><p>Forty children (3–17 years) were enrolled in the randomised open-label, controlled, pilot study. Patients were randomly assigned to the animal-assisted therapy-group (n = 20, who underwent a 20 min session with an animal-assisted therapy dog, after surgery) or the standard-group (n = 20, standard postoperative care). The study variables were determined in each patient, independently of the assigned group, by a researcher unblinded to the patient’s group. The outcomes of the study were to define the neurological, cardiovascular and endocrinological impact of animal-assisted therapy in response to stress and pain. Electroencephalogram activity, heart rate, blood pressure, oxygen saturation, cerebral prefrontal oxygenation, salivary cortisol levels and the faces pain scale were considered as outcome measures.</p><p>Results</p><p>After entrance of the dog faster electroencephalogram diffuse beta-activity (> 14 Hz) was reported in all children of the animal-assisted therapy group; in the standard-group no beta-activity was recorded (100% vs 0%, p<0.001). During observation, some differences in the time profile between groups were observed for heart rate (test for interaction p = 0.018), oxygen saturation (test for interaction p = 0.06) and cerebral oxygenation (test for interaction p = 0.09). Systolic and diastolic blood pressure were influenced by animal-assisted therapy, though a higher variability in diastolic pressure was observed. Salivary cortisol levels did not show different behaviours over time between groups (p=0.70). Lower pain perception was noted in the animal-assisted group in comparison with the standard-group (p = 0.01).</p><p>Conclusion</p><p>Animal-assisted therapy facilitated rapid recovery in vigilance and activity after anaesthesia, modified pain perception and induced emotional prefrontal responses. An adaptative cardiovascular response was also present.</p><p>Trial Registration</p><p>ClinicalTrials.gov <a href="https://clinicaltrials.gov" target="_blank">NCT02284100</a></p></div
