Clonidine as an adjuvant in the management of acute poisoning by anticholinesterase pesticides.

Anticholinesterase pesticides are widely used in agriculture and domestic settings throughout the world, and they are responsible for great morbidity and mortality. In Egypt and other developing countries, there is a pressing need for new affordable antidotes to treat anticholinesterase pesticide poisoning. Hence, this study was conducted to evaluate the safety and effectiveness of moderate doses of clonidine in the management of adult patients with acute anticholinesterase pesticide poisoning. This study was an open-label, phase II pilot clinical trial. Sixty patients with acute anticholinesterase pesticide poisoning gave consent to participate in the study. They were divided into 2 equal groups, with 30 patients in each group. Group I received clonidine plus the routine treatment, while group II received only the routine treatment. Patients were subjected to full history taking, and their vital and clinical data were recorded. Serum cholinesterase levels and routine laboratory investigations were measured. The different outcomes of the patients were assessed. The baseline characteristics of both groups were similar. Thirteen (43.3%) patients developed significant hypotension during clonidine treatment. The clinical outcomes (including mortality, need for assisted ventilation, length of hospital stay, and total doses of atropine) showed no significant differences between the two groups. The use of clonidine in acute anticholinesterase pesticide poisoning may be associated with a high incidence of hypotension requiring intervention. The clinical outcomes may not significantly improve in clonidine-treated patients.

The rate of preterm birth in the United States is affected by the method of gestational age assignment

The objective of the study was to examine the rate of preterm birth in the United States using 2 different methods of gestational age assignment and determine which method more closely correlates with the known morbidities associated with preterm birth. Using National Center for Health Statistics data from 2012 United States birth certificates, we computed the rate of preterm birth defined as a birth at 36 or fewer completed weeks with gestational age assigned using the obstetric estimate as specified in the revised birth certificate. This rate was then compared with the rate when gestational age is calculated using the last menstrual period alone. The rates of neonatal morbidities associated with preterm birth were examined for each method of assigning gestational age. The rate of preterm birth was 9.7% when the obstetric estimate is used to calculate gestational age, which is significantly different from the rate of 11.5% when gestational age is calculated using the last menstrual period alone. In addition, the neonates identified as preterm by obstetric estimate were more likely to qualify as low birthweight (54% vs 42%; P < .001) and suffer morbidities such as need for assisted ventilation and surfactant use than those identified with the last menstrual period alone. That is to say obstetric estimate is more sensitive and specific for preterm birth by all available markers of prematurity. The preterm birth rate is 9.7% vs 11.5% and more closely correlates with adverse neonatal outcomes associated with preterm birth when gestational age is assigned using the obstetric estimate. This method of gestational age assignment is currently used by most industrialized nations and should be considered for future reporting of US outcomes.

The Association of Vitamin D Status with Acute Respiratory Morbidity in Preterm Infants

To assess the association between serum 25-hydroxyvitamin D (25OHD) levels and outcomes in preterm infants (<32 weeks gestation). Serum 25OHD was measured in mothers and their infants within 24 hours of birth, before the start of enteral vitamin D supplementation, and at discharge from the neonatal intensive care unit. We evaluated the associations between vitamin D status and various early preterm outcomes. Ninety-four preterm infants and their mothers were included; 92% of the infants had a 25OHD level≤50 nmol/L (20 ng/mL), and 64% had a 25OHD level<30 nmol/L (12 ng/mL). A low 25OHD level (<30 nmol/L) in preterm infants at birth was associated with increased oxygen requirement (P=.008), increased duration of intermittent positive-pressure ventilation during resuscitation at delivery (P=.032), and greater need for assisted ventilation (P=.013). We observed a high prevalence of low 25OHD (<30 nmol/L), and found an association between vitamin D status and acute respiratory morbidity in preterm infants after birth.

Levetiracetam versus phenytoin in management of status epilepticus

The purpose of this study was to compare safety and efficacy of intravenous (IV) levetiracetam (LEV) with IV phenytoin (PHT) in management of status epilepticus (SE). The second-line treatment of SE is limited to a few drugs available in an IV formulation such as PHT, fosphenytoin and valproate. The relative lack of serious side effects and favourable pharmacokinetics of LEV made it a promising option in management of SE. Randomized trials comparing relative efficacy of second-line agents are remarkably lacking. In this study, consecutive patients of SE (n=44) were randomized to receive either IV PHT (20mg/kg) or IV LEV (20mg/kg). The primary end point was successful clinical termination of seizure activity within 30min after the beginning of the drug infusion. Secondary end points included recurrence of seizures within 24hours, drug related adverse effects, neurological outcome at discharge, need for ventilatory assistance, and mortality during hospitalization. Both LEV and PHT were equally effective with regard to primary and secondary outcome measures. PHT achieved control of SE in 15 (68.2%) patients compared to LEV in 13 (59.1%; p=0.53). Both the groups showed comparable results with respect to recurrence of seizures within 24hours (p=0.34), outcome at discharge as assessed by functional independence measure (p=0.68), need of ventilatory assistance (p=0.47) and death (p=1). From this study it can be concluded that LEV may be an attractive and effective alternative to PHT in management of SE.

Evaluation of serum troponin I in patients with acute exacerbations of chronic obstructive pulmonary disease

Abstract Introduction Chronic obstructive pulmonary disease is a common, preventable, and treatable disease. Troponin I is a component of the contractile proteins present in all muscles. The amino acid sequence of cardiac troponin I (cTnI) contains a section that is unique to cardiac muscle. Aim The aim of the study was to evaluate the incidence of cTnI elevation in patients with acute exacerbation of chronic obstructive pulmonary diseases (AECOPDs) and study the possible association of the level of cTnI with the severity of AECOPD, need for assisted ventilation, and length of hospital stay. Patients and methods This study was performed on 30 patients with AECOPD admitted to the Chest Department and Respiratory ICU at Benha University Hospital. On admission, all patients were subjected to full medical history taking and full clinical examination. We examined the patients for signs and symptoms of right ventricular (RV) failure. Echocardiography was performed for every patient. Serum troponin I levels (upon admission and 24 h later) were evaluated. Results The study showed 21 (70%) of 30 patients with positive troponin I versus nine (30%) with negative troponin I. There was a nonsignificant statistical difference among all studied AECOPD patients as regards smoking habits, as 89% of troponin I-negative patients were smokers versus 81% of troponin I-positive patients. When assessed on the basis of pulmonary function tests, 75% of troponin I-negative patients were found to be in moderate stage, 53% of troponin I-positive patients were in severe stage, and 33% of troponin I-positive patients were in very severe stage. There was a significant statistical difference in troponin elevation as regards pulmonary hypertension (71% of cTnI-positive patients vs. 11% of cTnI-negative patients), RV strain (90% of cTnI-positive patients vs. 33% of cTnI-negative patients), and tricuspid regurge (52% of cTnI-positive patients) but a nonsignificant difference as regards left ventricular dysfunction among all studied AECOPD patients. Conclusion cTnI in AECOPD patients is mostly positive in tachypneic, tachycardiac, hypoxemic, and hypercapnic patients with more severe pulmonary hypertension and RV dysfunction. Positive cTnI in AECOPD patients may suggest exacerbation severity, the need for mechanical ventilation (MV), and longer duration of hospitalization.

Medical intensive care unit consults occurring within 48 hours of admission: A prospective study

RationaleCritical care consults requested shortly after admission could represent a triage error. This consult process has not been adequately assessed, and data are retrospective relying on discharge diagnoses. ObjectivesThe aims of this study were to identify reasons for medical Intensive care unit (MICU) consultations within 48 hours of admission and to detect differences between those accepted and those denied MICU admission. MethodsData were prospectively collected including demographics, reason for consultation, Acute Physiology and Chronic Health Evaluation II score, Elixhauser comorbidity measure, functional status, need for assisted ventilation or vasopressor, presence of do-not-resuscitate (DNR) order, and whether a DNR order was obtained after MICU consultation. ResultsNinety-four percent of patients consulted were not initially evaluated in the emergency department, half of whom were accepted. Respiratory failure, sepsis, and alcohol withdrawal were the most frequent reasons for MICU transfers. Factors predicting MICU admission included respiratory illness, better baseline functional status, and less comorbidity, whereas DNR predicted rejection. We did not find differences in hospital mortality; but hospital length of stay was longer. ConclusionsProspective examination of the consult process suggests that disease progression rather than triage error accounted for most unplanned transfers. Functional status and comorbidity predicted MICU admission rather than illness severity. Goals of care were not being discussed adequately. We did not detect differences in mortality although hospital length of stay was increased.

Post-resuscitation care for neonates receiving positive pressure ventilation at birth.

To investigate if postresuscitation care (PRC) is indicated for all infants ≥35 weeks' gestation who receive positive pressure ventilation (PPV) at birth, explore the aspects of this care and the factors most predictive of it. Our hospital admits any infant who requires PPV at birth to special (intermediate/intensive) neonatal care unit (SNCU) for observation for at least 6 hours. All infants ≥35 weeks' gestation born between 1994 and 2013, who received PPV at birth, were reviewed. We examined perinatal factors that could predict the need for PRC after short (<1 minute) and prolonged (≥1 minute) PPV, admission course, neonatal morbidities, and the aspects of care given. Among 87 464 infants born, 3658 (4.2%) had PPV at birth with 3305 (90%) admitted for PRC. Of those, 1558 (42.6%) were in the short PPV group and 2100 (57.4%) in the prolonged PPV group. Approximately 59% of infants who received short PPV stayed in the SNCU for ≥1 day. Infants who received prolonged PPV were more likely to have morbidities and require special neonatal care. Multiple logistic regression analysis revealed the risk factors of placental abruption, assisted delivery, small-for-dates, gestational age <37 weeks, low 5-minute Apgar score, and need for intubation at birth to be independent predictors for SNCU stay ≥1 day and need for assisted ventilation, central lines, and parenteral nutrition. Our data support the need for PRC even for infants receiving short PPV at birth.

Neonatal morbidity in early-term newborns

Abstract Introduction In the last decades neonatal morbidity has increased significantly. The birth of children from 37 to 38 weeks of gestation, a period called early term, has significantly increased in the past twenty years or so, parallel to the increase in induced deliveries and the caesarean rate. Patients and method Retrospective cohorts’ population study, which included those babies born between 37 and 41 weeks of gestation in the period 1992–2011 (n = 35.539). This population was divided into two cohorts, early-term newborn (RNTP) of 37–38 weeks (n = 11,318), and full-term newborn (RNTC), of 39–41 weeks of gestation (n = 24,221). The rates of caesarean section, neonatal unit admission, respiratory morbidity, apnea, need for assisted ventilation, hyperbilirubinemia requiring phototherapy, hypoglycemia, seizures, hypoxic-ischaemia encephalopathy, need for parenteral nutrition and early sepsis were all reviewed. Results There was a progressive increase in the number of caesarean sections throughout the period studied (from 30.9% to 40.3%). The caesarean section rate was higher in RNTP than in the RNTC (38.3% vs. 31.3%, P Conclusions In our environment there is a significant number of RNTP, which have a significantly higher morbidity than newborns RNTC registered. After individualising each case, it is essential not to end a pregnancy before 39 weeks of gestation, except for maternal, placental or foetal conditions indicating that continuing the pregnancy may increase the risk for the foetus and/or the mother.

Background: Apnea of prematurity (AOP) is one of the most common respiratory disorder in the NICU. Methylxanthine derivatives have been administered to decrease the frequency of apneic episodes and prevent the need for assisted ventilation. AIMS: To compare the efficacy and adverse effects of caffeine and aminophylline in the management of AOP. Settings & design: It is a non-inferiority, randomized control trial in the NICU of tertiary care hospital. MATERIAL & METHODS: All intramural preterm neonates diagnosed as having AOP and satisfying the predefined inclusion criteria were randomized to receive either intravenous caffeine (n=20) or intravenous aminophylline (n=20) as per standard dosage and schedule. Neonates whose apnea episodes were not controlled by the assigned drugs were subsequently subjected to CPAP/mechanical ventilation. Apnea frequency was calculated to assess and compare efficacy of the either drug. Requirement and response to CPAP/mechanical ventilation was observed and adverse reactions to the either drug noted in each case. Statistical analysis: It was carried out by chi-square test & independent t-test. P value 50% reduction in apnea frequency was observed with the use of caffeine or aminophylline at the end of Day 5 of management. There was no significant difference (P >0.05) in the apnea frequency between the two groups on days 0, 1 and 5. Requirement and response of CPAP/mechanical ventilation was similar (P>0.05) with the use of either drug. Adverse effects like feeding intolerance and vomiting were more frequently associated with aminophylline as compared to caffeine. CONCLUSION: Intravenous caffeine was as efficacious as intravenous aminophylline in management of AOP and associated with relatively less adverse effects.

Effect of Intensive Atropine Doses (Rapid Incremental Loading and Titration) for Management of Organophosphorus Pesticide Poisoning: a Case Series

Background:Acute poisoning with organophosphorus (OP) pesticides is a common method of suicide and entails considerable mortality in Bangladesh. The objective of this study was to evaluate the effects and outcomes of a protocol for treatment of OP poisoning that included titrated incremental atropine as loading dose and slow infusion for maintenance. Methods:In this prospective descriptive case series, definitive OP poisoned patients were enrolled in an adult medicine unit of Dhaka Medical College Hospital from April 2006 to April 2007. Clinical examinations were done as soon as the patient entered the ward. Patient’s demographics, comorbid conditions and the occurrence of specific clinical outcomes including death, need for assisted ventilation and clinical complications were recorded. The patients were treated according to the protocol. Results: A total of 56 patients were enrolled over the study period. The median age of the study population was 22.5 years. Most patients were men (67.8%). The most common clinical presentation was miosis (58.9%). In total, 11 patients died (19.6%). Intermediate syndrome developed in 12 patients (21.4%) and 6 of them died. Assisted ventilation was required in 16 cases (28.5). Patients with diastolic blood pressure ≤ 70 mmHg and/or GCS ≤ 10 were significantly less likely to survive (P = 0.02, 0.006, respectively). Moreover, early respiratory failure (P < 0.001) and the need for assisted ventilation (P < 0.001) were significantly higher among deceased cases. The mortality rate in this study was similar to previous studies. The frequency of atropine toxicity in the present study (1.8%) was considerably lower than conventional regimen used in previous studies. Conclusion:Using the new protocol, lower rate of atropine toxicity developed in victims. Hence, the new protocol appears to be safer and its effectiveness should be further evaluated in case control studies in Bangladesh. How to cite this article: Ahmed AS, Basher A, Amin MR, Faiz MA.

Morbilidad neonatal en los recién nacidos a término precoz

IntroductionIn the last decades has increased significantly The birth of children from 37 to 38 weeks of gestation, a period called early term, has significantly increased in the past twenty years or so, parallel to the increase in induced deliveries and the cesarean rate. Patients and methodRetrospective cohorts population study, which included those babies born between 37 and 41 weeks of gestation in the period 1992-2011 (n=35.539). This population was divided into two cohorts, early term newborn (RNTP) of 37-38 weeks (n=11,318), and full term newborn (RNTC), of 39-41 weeks of gestation (n=24,221). The rates of cesarean section, neonatal unit admission, respiratory morbidity, apnea and need for assisted ventilation, hyperbilirubinemia requiring phototherapy, hypoglycemia, seizures, hypoxic-ischemia encephalopathy, need for parenteral nutrition and early sepsis were all reviewed. ResultsThere was a progressive increase in the number of caesarean sections throughout the period studied (from 30.9% to 40.3%). The cesarean section rate was higher in RNTP than in the RNTC (38.3% vs 31.3%, P<.0001). On comparing the two groups, significant differences were found in the rate of admission to neonatal unit, 9.1% vs 3.5% (P<.0001); respiratory morbidity (hyaline membrane 0.14% vs 0.007% [P<.0001], transient tachypnea 1.71% vs 0.45% [P<.0001], mechanical ventilation 0.2% vs 0.07% [P<.009], continuous positive airway pressure 0.11% vs 0.01% [P<.0001]), phototherapy 0.29% vs 0.07% (P<.0001), hypoglycemia 0.54% vs 0.11% (P<.0001), parenteral nutrition 0.16% vs 0.04% (P<.0001). There were no significant differences in the rate of early sepsis, pneumothorax, aspiration syndromes, seizures and hypoxic-ischemic encephalopathy. ConclusionsIn our environment, there is a significant number of RNTP, which have a significantly higher morbidity than newborns RNTC registered. After individualizing each case, it is essential not end a pregnancy before 39 weeks of gestation, except for maternal, placental or fetal conditions indicating that continuing the pregnancy may increase the risk for the fetus and/or the mother.

A prospective study of in-hospital mortality and discharge outcome in spontaneous intracerebral hemorrhage

Intracerebral hemorrhage (ICH) is associated with high mortality and morbidity. Various clinical and imaging predictors of mortality have been observed in previous studies. To study factors associated with in-hospital mortality in patients with ICH and observe the disability status of patients [assessed by modified Rankin scale (mRS)] at the time of discharge. Prospective observational study. All consecutive patients with acute hypertensive ICH admitted during the study period were enrolled. Data recorded included: Demographics, clinical, biochemical and cranial computed tomography (CT) findings. Primary outcome was defined as either death or survival within the hospital. mRS was used to assess outcome at discharge. Of the total 214 patients with ICH (193 supratentorial and 21 infratentorial), 70 (32.7%) patients died during the hospital stay. On bivariate analysis, low Glasgow Coma Scale (GCS) score, ventilatory assistance, higher hematoma volume, midline shift, hydrocephalus and intraventricular hematoma (IVH) were associated with mortality. ICH grading scale (ICH-GS) and ICH scores were higher in patients who died (P < 0.0001). Ninety-five (44.6%) patients underwent a neurosurgical intervention; 66 (45.8%) patients among the survivors compared with 29 (41.4%) among those who died (P = 0.54, Odds Ratio (OR) 0.83, 95% Confidence Interval (CI) 0.46-1.48). Independent predictors of mortality included a higher baseline hematoma volume ( P = 0.04 OR 1.01, 95% CI 1.00-1.02), lower GCS ( P = 0.01 OR 2.57, 95%CI 1.25-5.29), intraventricular extension of hematoma ( P = 0.007 OR 2.66, 95% CI 1.26-5.56) and ventilatory requirement (P < 0.0001 OR 8.34, 95%CI 2.75-25.38). Among survivors (n = 144), most were disabled [mRS 0-3, 7 (4.8%) and mRS 4-5, 137 (95.13%)] at discharge. Low GCS, higher baseline ICH volume, presence of IVH and need for ventilatory assistance are independent predictors of mortality. Most of the patients at discharge were disabled. Surgery did not improve mortality or outcome.

Pediatric index of mortality 2 score as an outcome predictor in pediatric Intensive Care Unit in India

Background and Aims:Pediatric index of mortality (PIM) 2 score is one of the severity scoring systems being used for predicting outcome of patients admitted to intensive care units (ICUs). The aim of the present study was to evaluate the usefulness of PIM2 score in predicting mortality in a tertiary care pediatric ICU (PICU) and to assess the associated factors in predicting mortality such as presence of shock, need for assisted ventilation and Glasgow coma scale <8.Materials and Methods:This was a prospective observation study done at tertiary care PICU from May 2011 to July 2011. Consecutive 119 patients admitted to PICU (aged 1 month to 12 years) were enrolled in the study. PIM2 scoring was done for all patients. The outcome was recorded as death or discharge. The associated factors for mortality were analyzed with SPSS 17.Results:PIM2 score discriminated between death and survival at a 99.8 cut-off, with area under receiver operating characteristic curve 0.843 with 95% confidence interval (CI) (0.765, 0.903). Most patients were referred late to this hospital, which explains higher death rate (46.2%), lesser length of hospital stay (mean 2.98 days) in the mortality group, and increased rate of mechanical ventilation (68.1%). Presence of shock was independently associated with mortality, as evidenced by binary logistic regression.Conclusion:PIM2 score discriminated well between survivors and death at PICU. Presence of shock was significantly associated with mortality.

Case Reports: We know that used in everyday European anesthetic practice sugammadex provides fast and efficient removal of the neuromuscular block, induced by steroidal muscle relaxants. Therefore suggests the use of sugammadex to accelerate weaning from mechanical ventilation patients with acute respiratory failure, requiring mechanical ventilation, synchronizing by steroid muscle relaxants. Description of sugammadex to accelerate weaning from mechanical ventilation patients with ARDS, synchronized by steroidal muscle relaxants.Preterm birth 3, operating 31 weeks of pregnancy. The scar on the uterus. Partial premature detachment of normally situated placenta. Antenatal fetal death. Acute disseminated intravascular coagulation. Pulmonary embolism, acute respiratory failure.Infarction-pneumonia. Prolonged mechanical ventilation (5 days: IPPV, BIPAP, CPAP; occasionally synchronized by rocuronium). Prolonged hemofiltration. Difficulty in weaning from prolonged mechanical ventilation, despite the clear consciousness, hemodynamic stability, successful co-operation of patients, doctors and nurses. 5 minutes after intravenous bolus injection of 400 mg sugammadex need for assisted ventilation was gone, the patient regained adequate spontaneous breathing, no longer even need a minimum of respiratory support. Sugammadex, in some cases can accelerate weaning the patient from the ventilator after prolonged mechanical ventilatory support, and therefore must take the appropriate place in the arsenal of intensive care medicine.

Risk factors for mortality in community-acquired pneumonia among children aged 1–59 months admitted in a referral hospital

To determine the case fatality rate and factors for death in community acquired pneumonia among children aged 1 month to 59 months admitted in a referral Hospital. Hospital based retrospective study. Institute of Child Health and Hospital for Children, Chennai. Case records of children aged 1 month to 59 months of age with pneumonia (clinically diagnosed pneumonia, radiologically diagnosed pneumonia, and clinically and radiologically diagnosed pneumonia), from January 2006 to December 2008. Outcome measures Case fatality rate (CFR) was calculated. Risk factors for mortality analyzed were young age of 1 to 6 months old, female sex, wheeze, respiratory rate >70/min, chest indrawing, altered level of consciousness, convulsions, shock, associated heart disease, recent measles, weight for age <-2 Z score and need for assisted ventilation. The association of risk factors to mortality was arrived at for all three categories of pneumonia cases separately. Case fatality rate was 8.2% (95% CI: 7.37- 8.99%). There was no significant difference in the CFR among the three study groups. Need for assisted ventilation alone was found to be an independent risk factor for mortality in children with pneumonia among all the study groups. Other risk factors like young age, weight for age <-2 Z score, altered level of consciousness, and congenital heart disease were also observed among these groups. Among 1 month to 59 months old hospitalized children with pneumonia, CFR was 8.2%. Need for assisted ventilation was a significant risk factor associated with mortality.

Severity of Influenza A 2009 (H1N1) Pneumonia Is Underestimated by Routine Prediction Rules. Results from a Prospective, Population-Based Study

BackgroundCharacteristics of patients with community-acquired pneumonia (CAP) due to pandemic influenza A 2009 (H1N1) have been inadequately compared to CAP caused by other respiratory pathogens. The performance of prediction rules for CAP during an epidemic with a new infectious agent are unknown.MethodsProspective, population-based study from November 2008–November 2009, in centers representing 70% of hospital beds in Iceland. Patients admitted with CAP underwent evaluation and etiologic testing, including polymerase chain reaction (PCR) for influenza. Data on influenza-like illness in the community and overall hospital admissions were collected. Clinical and laboratory data, including pneumonia severity index (PSI) and CURB-65 of patients with CAP due to H1N1 were compared to those caused by other agents.ResultsOf 338 consecutive and eligible patients 313 (93%) were enrolled. During the pandemic peak, influenza A 2009 (H1N1) patients constituted 38% of admissions due to CAP. These patients were younger, more dyspnoeic and more frequently reported hemoptysis. They had significantly lower severity scores than other patients with CAP (1.23 vs. 1.61, P = .02 for CURB-65, 2.05 vs. 2.87 for PSI, P<.001) and were more likely to require intensive care admission (41% vs. 5%, P<.001) and receive mechanical ventilation (14% vs. 2%, P = .01). Bacterial co-infection was detected in 23% of influenza A 2009 (H1N1) patients with CAP.ConclusionsClinical characteristics of CAP caused by influenza A 2009 (H1N1) differ markedly from CAP caused by other etiologic agents. Commonly used CAP prediction rules often failed to predict admissions to intensive care or need for assisted ventilation in CAP caused by the influenza A 2009 (H1N1) virus, underscoring the importance of clinical acumen under these circumstances.

Surfactant for pulmonary haemorrhage in neonates

In the 1960s and 1970s, pulmonary haemorrhage (PH) occurred mainly in full-term infants with pre-existing illness with an incidence of 1.3 per 1000 live births. Risk factors for PH included severity of illness, intrauterine growth restriction, patent ductus arteriosus (PDA), coagulopathy and the need for assisted ventilation. Presently, PH occurs in 3% to 5% of preterm ventilated infants with severe respiratory distress syndrome (RDS) who often have a PDA and have received surfactant. The cause of PH is thought to be due to rapid lowering of intrapulmonary pressure, which facilitates left to right shunting across a PDA and an increase in pulmonary blood flow. Retrospective case reports and one prospective uncontrolled study have shown promising results for surfactant in treating PH. To evaluate the effect of surfactant treatment compared to placebo or no intervention on mortality and morbidities in neonates with PH. For this update The Cochrane Library, Issue 2, 2012; MEDLINE; EMBASE; CINAHL; Clinicaltrials.gov; Controlled-trials.com; proceedings (2000 to 2011) of the Annual Meetings of the Pediatric Academic Societies (Abstracts2View) and Web of Science were searched on 8 February 2012. Randomised or quasi-randomised controlled trials that evaluated the effect of surfactant in the treatment of PH in intubated term or preterm (< 37 weeks) neonates with PH. Infants were included up to 44 weeks' postmenstrual age. The interventions studied were intratracheal instillation of surfactant (natural or synthetic, regardless of dose) versus placebo or no intervention. If studies were identified by the literature search, the planned analyses included risk ratio, risk difference, number needed to treat to benefit or to harm for dichotomous outcomes, and mean difference for continuous outcomes, with their 95% confidence intervals. A fixed-effect model would be used for meta-analyses. The risk of bias for included trials would be assessed. Heterogeneity tests, including the I(2) statistic, would be performed to assess the appropriateness of pooling the data and the results would be reported. No trials were identified. No randomised or quasi-randomised trials that evaluated the effect of surfactant in PH were identified. Therefore, no conclusions from such trials can be drawn. In view of the promising results from studies with less strict study designs than a randomised controlled trial, there is reason to conduct further trials of surfactant for the treatment of PH in neonates.

Treatment of Haemophilus bacteremia with benzylpenicillin is associated with increased (30-day) mortality

BackgroundOptimal antibiotic treatment strategies of Haemophilus infections are still needed. Therefore, 30-day case fatality rate (CFR) of Haemophilus bacteremia and efficacy of various antibiotic treatment regimes were studied.MethodsAll episodes of Haemophilus bacteremia in the former Copenhagen County during the period 2000-9 were included in the study. Clinical and biochemical findings and outcome were collected retrospectively from medical records.Results105 consecutive episodes were identified (median age: 69 years, with only 4 children <16 years), 72% were due to non-typeable -, 16% to typeable H. influenzae, and 11% to other Haemophilus species. Pneumonia was the most common primary focus (in 48%), and 58% of the patients had Charlson comorbidity index > 1. Definitive antibiotic therapy was in 26 cases benzylpenicillin, in 12 cases aminopenicillins, in 50 cases cefuroxime and in 16 cases broadspectrum antibiotics, whereas 1 palliative case died without start of therapy. Whereas the use of broadspectrum antibiotics was related to the severity of the disease (admittance to ICU, need for assisted ventilation or hemodialysis, septic shock), no significant difference in clinical features was demonstrated for therapy with benzylpenicillin, aminopenicillin or cefuroxime, except benzylpenicillin was rarely administered to immunosuppressed patients. The CFR was 22% (23/105). The choice of empiric antibiotic therapy was not significantly associated with mortality (adequate vs. inadequate treatment: 23% (21/93) vs. 17% (2/12), respectively, P > 0.05). In contrast, definite antibiotic therapy with cefuroxime or aminopenicillins resulted in a significantly lower CFR than treatment with benzylpenicillin (12% (6/50) or 0% (0/12) vs. 39% (10/26), respectively, Log rank test P < 0.02). When adjustments were made for other identified risk factors in bivariate logistic regression analysis, treatment with cefuroxime was still were found to be associated with a significantly lower CFR than for benzylpenicillin: OR: 0.21 (0.06-0.69), P = 0.01 (hospital-acquired bacteremia), OR: 0.27 (0.08-0.91), P = 0.04 (polymicrobial episodes), OR: 0.16 (0.04-0.59), P = 0.006 (admittance at intensive care unit), OR: 0.22 (0.06-0.82), P = 0.02 (alcohol abuse), OR: 0.15 (0.04-0.60), P = 0.008 (altered mental state), OR: 0.22 (0.07-0.71), P = 0.01 (temperature < 38 °C), OR: 0.23 (0.07-0.79), P = 0.02 (septic shock), OR: 0.21 (0.06-0.69), P = 0.01 (mechanical ventilation).ConclusionOur results suggest that, after susceptibility testing, cefuroxime or aminopenicillins are preferable to benzylpenicillins as definitive therapy for Haemophilus bacteremia.

Intermittent manually controlled versus continuous infusion of propofol for deep sedation during interventional endoscopy: A prospective randomized trial

Introduction. Beside the traditional, intermittent bolus application of propofol, continuous propofol infusion via infusion pump is an alternative procedure for deep sedation during long-lasting interventional endoscopy. However, up to now, there are no randomized comparisons for gastrointestinal endoscopy. Methods. One hundred patients (ERCP: n = 60, EUS: n = 40) were randomly assigned to receive intermittent bolus application (“bolus group”) or continuous infusion (“perfusor group”) of propofol sedation after induction with 3 mg midazolam for deep sedation. Patients in the bolus group received an initial propofol dose according to body weight (bw <70 kg: 40 mg; bw ≥70 kg 60 mg). In the perfusor group, bw-adapted, continuous propofol infusion (6 mg/kg) via the Injectomat 2000 MC (Fresenius-Kabi) was administered after an initial bolus of 1 mg/kg. Vital signs, dose of propofol, patient cooperation (VAS 1–10), sedation depth, and the recovery time as well as the quality of recovery were evaluated. Results. Total propofol dose in the bolus group 305 ± 155 mg (100–570 mg) and in the perfusor group 343 ± 123 mg (126–590 mg, p = 0.5) were comparable. Oxygen saturation below 90% was seen in four patients of each group, with no need for assisted ventilation. Arterial blood pressure <90 mmHg was documented in two patients in the bolus group and seven patients in the perfusor group (p = 0.16). Patients' cooperation was rated as good in both groups (bolus group, 9.1 ± 0.9; perfusor group, 8.9 ± 1; p = 0.17). Recovery time was significantly shorter in the bolus group compared with the perfusor group (19 ± 5 versus 23 ± 6 min, p < 0.001) whereas the quality of recovery was nearly identical in both groups. Conclusion. Both sedation regimens allow nearly identical good controllability of propofol sedation. However, recovery time was significantly slower and hypotension was tended to occur more often in the perfusor group.
