Nalbuphine and tramadol are potent analgesic drugs. Our aim was to preliminarily assess and compare the efficacy and safety of nalbuphine and tramadol for postoperative analgesia in children. In a double-blind design, 24 ASA 1-3 children aged 1 to 10 years undergoing a scheduled surgical procedure were randomly allocated to receive either an intravenous bolus dose of nalbuphine 100 microg/kg immediately before the end of surgery followed by an infusion of 0.2 microg/kg/min for 72 hrs., or an intravenous bolus dose of tramadol 1000 microg/kg followed by an infusion of 2.0 microg/kg/min for 72 hrs. Postoperative pain control and drug-related adverse events were recorded. Three children who received nalbuphine required an extra bolus dose within the 12 hrs. of post-surgery versus one child in the tramadol group. A similar number of patients in both groups required an increment in the infusion rate within the 72 post-surgery hours. Sedation was observed in 2 children in the nalbuphine group and in 1 child in the tramadol group. Four children presented vomiting with tramadol and two with nalbuphine. Cardiovascular parameters remained within the normal ranges in both groups. In conclusion, the bolus/infusion regimen of tramadol evaluated in this study appears to have better postoperative analgesic efficacy than the bolus/infusion regimen of nalbuphine. These preliminary results require further confirmation by studies with a sample size enough to clearly identify differences in their efficacy as well as in the rate of adverse events secondary to the administration of each of them.

Different antimicrobial treatments have proved to be effective in patients with aspiration pneumonia. However, resistant bacterial strains are commonly observed in hospital settings challenging the empirical treatment of these patients. In this study, we aimed to compare the efficacy of cefepime/clindamycin and ceftriaxone/clindamycin for empiric therapy of poisoned patients with aspiration pneumonia. In an open, randomized, prospective design, 140 consecutive patients aged more than 13 years, with radiographic signs of infiltration in chest radiography and dullness on percussion or pulmonary rales or ronchi in combination with at least two of the following clinical criteria were considered as eligible: fever > or = 37 degrees C (axillary), or hypothermia < 35 degrees C (axillary) and leukocytosis (> 10 cells/mm3), or leukopenia (< 3,000 cells/mm3), a left-shift of > 10%, or purulent sputum or secretion from trachea or bronchi. Participants received intravenously either ceftriaxone 1 g q12 h and clindamycin 900 mg q8 h (group 1) or cefepime 1 g q12 h and clindamycin 900 mg q8 h (group 2). On day 5 of treatment, the number of improved/cured patients was not different between groups (OR 0.86; 95% CI 0.24 to 2.90) nor at 14 days of the study (OR 0.66; 95% CI 0.12 to 3.29). Six patients died in group 1 and 5 in group 2 (RR 0.83; 95% CI 0.28 to 2.46). In conclusion, efficacy of empiric treatment of poisoned patients with aspiration pneumonia with ceftriaxone/clindamycin was comparable to treatment with cefepime/clindamycin.

We present a 1.5-year old, 11 kg, female infant with a history of bronchial hyper-responsiveness who accidentally ingested half of a "Chinese chalk". A day later, the infant showed vomiting, cough, fever, drowsiness, and irritability and her clinical conditions progressively worsened. She was admitted to the emergency department with cough, respiratory distress, and hepatomegaly. It has been reported that the chalk may contain deltamethrin and cypermethrin. The patient was successfully treated with supportive therapy. This report identifies "Chinese chalk" as a potential source of accidental poisoning in children and should be considered as part of the differential diagnoses in the emergency rooms since poisoning with these compounds may be misdiagnosed as organophosphate poisoning due to the presentation of similar symptoms.

Sophrology, based on a combination of Western relaxation therapy and Eastern yoga and meditation might decrease maternal stress during labor. This study aimed to evaluate whether prenatal sophrologic childbirth preparation may decrease maternal and neonatal adverse response associated with delivery. In a nested case-control study, 69 nulliparous, singleton pregnant women who underwent an educational course of sophrologic childbirth preparation were compared to 69 nulliparous, singleton, age- and gestational age-matched pregnant women who did not receive any childbirth preparation. All babies were vaginally delivered. Groups were not different (P > 0.05) in the number of neonates born with meconium-stained amniotic fluid as well as in the number of babies with Apgar score < or = 7 at 1 and 5 minutes after birth. Duration of labor was not different between groups. The number of women requiring oxytocin and delivering babies with low pH blood levels tended to be lower in the group undergoing sophrologic childbirth preparation, i.e. 58.0% vs 72.5% (P = 0.07) and 1.4% vs 10.9% (P = 0.06), respectively. In conclusion, we were unable to confirm that prenatal sophrologic childbirth preparation has a definitive role in decreasing adverse maternal and fetal response to pain or in shortening labor. Prospective cohort studies with a larger sample size or randomized trials may help to clarify this gap.

In order to evaluate how spontaneously born piglets could be a suitable model for the study of intrapartum hypoxia, 230 newborn piglets were studied. Out them, 8.3% (n = 19) died intrapartum, 21.7% (n = 50) were born with moderate-to-severe intrapartum hypoxia, and 70% (n = 161) were born with mild or no evidence of intrapartum distress. Piglets born without any evidence of intrapartum asphyxia weighed approximately 240 g lower than those born with intrapartum hypoxia and intrapartum-dead piglets (P<0.0001). The viability score was approximately 3 units lower and the latency to contact the udder was two times longer in the piglets surviving intrapartum hypoxia than in controls (P <0.0001). In comparison with the control group, metabolic acidosis was most severe among intrapartum-dead piglets followed by piglets surviving intrapartum asphyxia (P =0.002). According to a multiple linear regression analysis, pCO2 and lactate blood levels, and birth weight were identified as explanatory variables of viability score (r: 0.78; P <0.001). Viability score, K+ and lactate blood levels, and birth weight were identified as explanatory variables of latency to contact the udder (r: 0.80; P <0.001). In conclusion, the spontaneously-born asphyxiated piglet could be considered as a naturalistic model for the study of intrapartum asphyxia. Histopathologic and more rigorous functional and behavioral evaluations are still required to further characterize the model. (www.actabiomedica.it)

Although the efficacy of laryngeal mask airway (LMA) has been demonstrated for securing patency of the airway in children, it has not yet been compared to endotracheal tube (ET) in this population. This study aimed to compare the safety and efficacy of LMA vs. ET in children undergoing elective diagnostic upper gastrointestinal endoscopies. Sixty ASA I-III patients were randomly allocated to ET (Group I) or LMA (Group II). A set of cardiovascular and respiratory parameters were obtained before, during and after the endoscopic procedure. The recovery time and the time to discharge were also registered. The cardiovascular and respiratory parameters evaluated in the study varied across the different evaluation periods. However, they remained within physiological ranges and were not different between groups. The median (range) recovery time was 4 (2-10) min and the time to discharge was 58 (36-88) min in the ET group and 3 (1-7) min and 50 (35-67) min in the LMA group (P > 0.10), respectively. In a 16 month-old, 80 cm and 10 kg girl, we failed to secure the patency of the airway with LMA. In conclusion, the LMA was as effective and safe as ET for securing the airway of children undergoing diagnostic upper endoscopies. However, the 3% failure rate occurred with LMA.
