RESUMO

INTRODUCTION: Enhanced clinical outcomes in the Paediatric Intensive Care Unit following standardisation of analgesia and sedation practice are reported. Little is known about the impact of standardisation of analgesia and sedation practice including incorporation of a validated distress assessment instrument on infants post cardiac surgery, a subset of whom have Trisomy 21. This study investigated whether the parallel introduction of nurse-led analgesia and sedation guidelines including regular distress assessment would impact on morphine administered to infants post cardiac surgery, and whether any differences observed would be amplified within the Trisomy 21 population. METHODOLOGY: A retrospective single centre before/after study design was used. Patients aged between 44 weeks postconceptual age and one year old who had open cardiothoracic surgery were included. RESULTS: 61 patients before and 64 patients after the intervention were included. After the intervention, a reduction in the amount of morphine administered was not evident, while greater use of adjuvant sedatives and analgesics was observed. Patients with Trisomy 21 had a shorter duration of mechanical ventilation after the change in practice. CONCLUSION: The findings from this study affirm the importance of the nurses' role in managing prescribed analgesia and sedation supported by best available evidence. A continued education and awareness focus on analgesia and sedation management in the pursuit of best patient care is imperative.

RESUMO

BACKGROUND: Measurement of forearm blood pressure (BP) in pediatric patients during general anesthesia is periodically employed despite a lack of evidence for this practice. Upper arm BP measurement may be impossible to perform for either patient or surgical reasons, and the forearm has theoretical benefits over the lower leg when an alternate site is required. We hypothesize that forearm BP measurement provides an accurate and reliable alternative to the upper arm. Published adult data do not support this hypothesis, and the little pediatric data published contain methodological shortcomings. METHODS: A dedicated, externally calibrated noninvasive oscillometer was used to compare BP measurements in the upper arm and ipsilateral forearm of pediatric patients undergoing general anesthesia prior to application of a surgical stimulus. Both upper arm BP and ipsilateral forearm BP were sequentially measured 20 seconds apart on 3 separate occasions with an appropriately sized cuff. The systolic, diastolic, and mean blood pressures were recorded under steady-state conditions. RESULTS: Thirty-five elective surgical patients aged 1 to 10 years were studied. The bias (±limits of agreement) for forearm minus upper arm blood pressures were as follows: mean BP -1.3 mm Hg (±7.2), diastolic BP -3.3 (±5.3), and systolic BP +3.2 mm Hg (±8.3). Differences greater than ±5 mm Hg occurred in 59% (systolic BP), 42% (diastolic BP), and 46% (mean BP) of all observations and greater than ±10 mm Hg in 17% (systolic BP), 8.6% (diastolic BP), and 15% (mean BP). CONCLUSION: The differences within mean ±1.96 standard deviations reside considerably outside the clinically accepted tolerance of ±5 mm Hg. Thus, the forearm may not be used interchangeably with upper limb BP readings in anesthetized healthy children. Future use of the forearm for BP measurement requires a validated anthropomorphically appropriate forearm cuff.

RESUMO

OBJECTIVE: To compare the pharmacodynamics and pharmacokinetics of IV morphine after cardiac surgery in two groups of children-those with and without Down syndrome. DESIGN: Prospective, single-center observational trial. SETTING: PICU in a university-affiliated pediatric teaching hospital. PATIENTS: Twenty-one children with Down syndrome and 17 without, 3-36 months old, scheduled for cardiac surgery with cardiopulmonary bypass. INTERVENTIONS: A loading dose of morphine (100 µg/kg) was administered after coming off bypass; thereafter, morphine infusion was commenced at 40 µg/kg/hr. During intensive care, nurses regularly assessed pain and discomfort with validated observational instruments (COMFORT-Behavior scale and Numeric Rating Scale-for pain). These scores guided analgesic and sedative treatment. Plasma samples were obtained for pharmacokinetic analysis. MEASUREMENTS AND MAIN RESULTS: Median COMFORT-Behavior and Numeric Rating Scale scores were not statistically significantly different between the two groups. The median morphine infusion rate during the first 24 hours after surgery was 31.3 µg/kg/hr (interquartile range, 23.4-36.4) in the Down syndrome group versus 31.7 µg/kg/hr (interquartile range, 25.1-36.1) in the control group (p = 1.00). Population pharmacokinetic analysis revealed no statistically significant differences in any of the pharmacokinetic variables of morphine between the children with and without Down syndrome. CONCLUSIONS: This prospective trial showed that there are no differences in pharmacokinetics or pharmacodynamics between children with and without Down syndrome if pain and distress management is titrated to effect based on outcomes of validated assessment instruments. We have no evidence to adjust morphine dosing after cardiac surgery in children with Down syndrome.

RESUMO

Background and Aim. Spiral enteroscopy (SE) is a new small bowel endoscopic technique. Our aim is to review the diagnostic and therapeutic yield, safety of SE, and the predictive role of prior capsule endoscopy (CE) at an academic center. Methods. A retrospective review of patients undergoing SE after prior CE between 2008 and 2013 was performed. Capsule location index (CLI) was defined as the fraction of total small bowel transit time when the lesion was seen on CE. Results. A total of 174 SEs were performed: antegrade (147) and retrograde (27). Abnormalities on SE were detected in 65% patients. The procedure was safe in patients with surgically altered bowel anatomy (n = 12). The diagnostic yield of antegrade SE decreased with increasing CLI range. The diagnostic yield of retrograde SE decreased on decreasing CLI range. A CLI cutoff of 0.6 was derived that determined the initial route of SE. Vascular ectasias seen on CE were detected in 83% cases on SE; p < 0.01. Conclusions. SE is safe with a high diagnostic and therapeutic yield. CLI is predictive of the success of SE and determines the best route of SE. The type of small bowel pathology targeted by SE may affect its utility and yield.

RESUMO

Conventional algorithms for diagnosis and treatment of gastrointestinal bleeding (GIB) in patients with nonpulsatile ventricular assist devices (VADs) may take days to perform while patients require transfusions. We developed a new algorithm based on deep overtube-assisted enteroscopy (DOAE) to facilitate a rapid diagnosis and treatment. From 2004 to 2012, 84 patients who underwent VAD placement in our institution, were evaluated for episodes of GIB. Our new algorithm for the management of GIB using DOAE was evaluated by dividing the episodes into three groups: group A (traditional management without enteroscopy), group B (traditional management with enteroscopy performed >24 hours after presentation), and group C (new management algorithm with enteroscopy performed <24 hours after presentation). Gastrointestinal bleeding was observed in 14 (17%) of our study patients for a total of 45 individual episodes of which 28 met our criteria for subanalysis. Forty-one (84%) lesions were confined to the upper gastrointestinal tract with more than 91% of these lesions being arteriovenous malformations. Average number of transfusions in groups A, B, and C were 4.1, 6.3, and 1.3, respectively (p = 0.001). The number of days to treatment was significantly shorter in group C than group B (0.4 vs. 5.3 days, p = 0.0002). Our new algorithm for the management of GIB using DOAE targets the most common locations of bleeding found in this patient population. When performed early, DOAE has the potential to decrease the need for transfusions and allow for an early diagnosis of GIB in VAD recipients.

RESUMO

We describe the presentation of bilateral pneumothoraces with pulmonary oedema following an elective tracheostomy. A 69-year-old man underwent panendoscopy following primary chemoradiotherapy for locally invasive vocal cord carcinoma. A tracheostomy was performed for upper airway oedema and necrosis. Postoperatively, acute airway obstruction with profound desaturation developed. Tracheostomy tube suctioning dislodged an airway clot with clinical improvement and restoration of bilateral breath sounds. A chest X-ray subsequently demonstrated bilateral pneumothoraces with marked pulmonary oedema. Management, including chest drain insertion, resulted in stabilisation and subsequent full recovery. This case highlights the potential for more than one cause of life-threatening complication following tracheostomy. The importance of considering multiple pathologies in the setting of severe hypoxia and to institute prompt management is emphasised.

RESUMO

A six week old infant underwent ventricular septal defect and atrial septal defect closure. Preoperative echocardiography showed evidence of pulmonary hypertension. The post operative course was complicated failure to wean from ventilatory and inotropic support. Echocardiography showed severe left ventricular (LV) dysfunction and suggested some fistulous drainage of the left coronary artery into the right pulmonary artery; this anomalous drainage of the left coronary artery into the right pulmonary artery (ALCAPA) was confirmed with coronary angiogram. Re-implantation of the left coronary artery into the aorta was performed. Extra-corporeal membrane oxygenation (ECMO) was required to allow time for ventricular recovery. Supports were weaned gradually, with concurrent evidence of LV recovery and the child was discharged on postoperative day 30. ALCAPA is rare and typically presents at 8 weeks of age with symptoms of heart failure, as pulmonary pressure falls leading to myocardial ischaemia due to myocardial hypoperfusion with relatively desaturated blood. In our case the pulmonary hypertension and left to right shunt preoperatively were protective, maintaining forward flow of relatively oxygenated blood. While protective to the myocardium this made the preoperative diagnosis of ALCAPA difficult, as there was no flow reversal on Doppler echocardiography. Closure of the septal defects meant this protective effect was lost, with subsequent severe myocardial ischaemia and heart failure. This case highlights the diagnostic challenges of ALCAPA, the 'protective' effects of pulmonary hypertension with ALCAPA, and the importance of early cardiac catheterization in the setting of unexplained failure to wean post cardiac surgery.

RESUMO

OBJECTIVE: To compare neurally adjusted ventilatory assist ventilation with pressure-support ventilation. DESIGN: Prospective, crossover comparison study. SETTING: Tertiary care pediatric and neonatal intensive care unit. PATIENTS: Sixteen ventilated infants and children: mean age = 9.7 months (range = 2 days-4 yrs) and mean weight = 6.2 kg (range = 2.4-13.7kg). INTERVENTIONS: A modified nasogastric tube was inserted and correct positioning was confirmed. Patients were ventilated in pressure-support mode with a pneumatic trigger for a 30-min period and then in neurally adjusted ventilatory assist mode for up to 4 hrs. MEASUREMENTS AND MAIN RESULTS: Data collected for comparison included activating trigger (neural vs. pneumatic), peak and mean airway pressures, expired minute and tidal volumes, heart rate, respiratory rate, pulse oximetry, end-tidal CO2 and arterial blood gases. Synchrony was improved in neurally adjusted ventilatory assist mode with 65% (+/-21%) of breaths triggered neurally vs. 35% pneumatically (p < .001) and 85% (+/-8%) of breaths cycled-off neurally vs. 15% pneumatically (p = .0001). The peak airway pressure in neurally adjusted ventilatory assist mode was significantly lower than in pressure-support mode with a 28% decrease in pressure after 30 mins (p = .003) and 32% decrease after 3 hrs (p < .001). Mean airway pressure was reduced by 11% at 30 mins (p = .13) and 9% at 3 hrs (p = .31) in neurally adjusted ventilatory assist mode although this did not reach statistical significance. Patient hemodynamics and gas exchange remained stable for the study period. No adverse patient events or device effects were noted. CONCLUSIONS: In a neonatal and pediatric intensive care unit population, ventilation in neurally adjusted ventilatory assist mode was associated with improved patient-ventilator synchrony and lower peak airway pressure when compared with pressure-support ventilation with a pneumatic trigger. Ventilating patients in this new mode seem to be safe and well tolerated.

RESUMO

OBJECTIVE: To investigate the long-term health-related quality of life (HRQOL) outcomes for patients requiring at least 28 days of pediatric intensive care. DESIGN: Retrospective cohort and prospective follow-up study. SETTING: A 21-bed pediatric intensive care unit (PICU) in a university-affiliated, tertiary referral pediatric hospital. PATIENTS: One hundred ninety-three patients who spent 28 days or longer in the PICU between January 1, 1997 and December 31, 2004. INTERVENTIONS: Quality of life was measured using the Pediatric Quality of Life Inventory (Peds QL 4.0) parent-proxy version at 2 to 10 yrs after discharge. The PedsQL 4.0 is a modular measure of HRQOL, which is reliable in children aged 2 to 18 yrs. It generates a total score and physical, emotional, social, school, and psychosocial subscores. MEASUREMENTS AND MAIN RESULTS: Of the 193 patients, 41 died during their PICU admission and 27 died between PICU discharge and follow-up. Quality of life questionnaires were posted to parents of 108 of the 125 survivors and 70 were returned completed. Forty children (57.1%) had scores indicating a normal quality of life, whereas 30 (42.9%) had scores indicating impaired HRQOL. Of these, 14 (20%) had scores indicating poor quality of life with ongoing disabling health problems requiring hospitalization or the equivalent. CONCLUSIONS: Our results indicate that, while long PICU stay is associated with significant mortality, the long-term HRQOL is normal for the majority of surviving children.

RESUMO

BACKGROUND: Tonsillectomy is a common pediatric surgical procedure resulting in significant postoperative pain. There is ongoing controversy as to the most satisfactory analgesic regimen. Nonsteroidal antiinflammatory drugs (NSAIDs) are an alternative to opioids in this setting. NSAID use in tonsillectomy has been shown to be opioid sparing in the recovery period and to have similar analgesic effects to opioids in pediatric patients. Because of their nonspecific action on the enzyme cyclo-oxygenase there is potential for increased bleeding which has led many practitioners to avoid NSAIDs completely in this patient population potentially resulting in suboptimal pain control. Our aim in this study was to assess the effect of preoperatively administered diclofenac on the blood clot strength in children undergoing (adeno-) tonsillectomy. METHODS: Twenty patients undergoing (adeno-) tonsillectomy were recruited into this prospective observational study. All patients received 2 mg.kg(-1) of diclofenac rectally immediately preoperatively. Blood was taken for thromboelastograph analysis pre-diclofenac and 1 and 4 h post-diclofenac administration. RESULTS: There was a statistically significant increase in maximal clot strength (MA) at 1 and 4 h after diclofenac. Similarly there was a statistically significant reduction in time to initial fibrin formation (R time) post-diclofenac. There was no primary or secondary hemorrhage. CONCLUSIONS: Diclofenac when given preoperatively does not adversely affect clot strength in the immediate postoperative period when the risk of primary hemorrhage is greatest.

RESUMO

BACKGROUND: Nonsteroidal anti-inflammatory drugs (NSAIDs) are commonly used as perioperative analgesics. Many are currently used off label. Diclofenac is currently licensed for use in children over 1 year of age for the treatment of juvenile rheumatoid arthritis, while ibuprofen is licensed for use in children weighing over 7 kg. The dose and interval in children is currently extrapolated from adult studies, as the pharmacokinetic (PK) and pharmacodynamic (PD) data are lacking in infants. METHODS: A postal questionnaire was sent to members of the Association of Paediatric Anaesthetist of Great Britain and Ireland seeking to clarify members' prescribing patterns of NSAIDs, especially in infants. Information regarding the choice of NSAIDS, route of administration, lower age limit, dose interval, dose and practice in two specific perioperative contexts (adenotonsillectomy and open heart surgery) was sought. RESULTS: The response rate was 80%. NSAIDs are used by 86% of responders in infants. Diclofenac is most commonly used intraoperatively (78%); while ibuprofen (73%) was used more frequently postoperatively. NSAIDs are used by 21% of respondents in ICU. Commonest routes of administration were oral (81%) and rectal (80%), rarely intravenously (9%). The commonest dose for diclofena is 1 mg x kg(-1) (59%); the dosing schedule employed being 8 hourly in 53% of cases. NSAIDs are used by 57% of responders as part of their analgesic regime for adenotonsillectomies. CONCLUSION: Members of the Association of Paediatric Anaesthetists of Great Britain and Ireland commonly prescribe NSAIDs in infants. This is despite the dearth of PK and PD data in this age group.

RESUMO

The ovarian surface epithelium (OSE) is a single layer of flattened or cuboidal cells covering the ovary. Ninety percent of all human ovarian malignancies arise from this layer of cells. Incessant ovulation, hyperovulation induced by infertility treatment, and hormone replacement therapy have been suggested as risk factors for ovarian cancer. In this study, two groups of rats, with and without surgically induced injury to the ovary, were treated with 17beta-estradiol, pregnant mare's serum gonadotropin (PMSG), human chorionic gonadotropin (hCG), or the combination PMSG/hCG, and the proliferative response of the OSE cells was measured using bromodeoxyuridne (BrdU) and (3)H-thymidine. All hormones, alone or in combination with ovarian surgery, were found to increase significantly the rate of proliferation of the rat OSE. These data demonstrate that hormones associated with infertility treatments and hormone replacement therapy, as well as injury- or ovulation-induced rupture of the ovarian surface, stimulate the rat OSE, and hence could have a role in the development of ovarian cancer via proliferation-associated mutagenesis, or alternatively, by promoting the rapid selection of OSE cells with accumulated mutations.

RESUMO

Argon plasma coagulation (APC) is based on the principle of ionized argon creating a conductive plasma between an activating electrode and a tissue surface. To date, its use in tonsillectomy has not been extensively examined. The purpose of this randomized controlled trial was to assess the clinical efficacy of APC as a tool for this common surgical procedure. Forty patients were randomized into two groups--treatment A (conventional tonsillectomy, n = 20) and treatment B (APC tonsillectomy, n = 20). Trial end-points included a) operative time, b) intra-operative blood loss, and c) objective assessment of post-operative pain, by completion of a visual analogue pain score chart, over a two-week period. Thirty-one patients were available for analysis. There was a statistically significant reduction in the intra-operative blood loss with treatment B (p = 0.02). There was no statistical difference between both groups for the other outcome measures. First clinical experience with this treatment modality shows that it is an attractive alternative to conventional tonsillectomy and may offer possible benefits.
