[The predictive value of plasma B-type natriuretic peptide levels on outcome in children with pulmonary hypertension undergoing congenital heart surgery].
In children undergoing congenital heart surgery, plasma brain natriuretic peptide levels may have a role in development of low cardiac output syndrome that is defined as a combination of clinical findings and interventions to augment cardiac output in children with pulmonary hypertension. ⋯ In patients with pulmonary hypertension undergoing congenital heart surgery, 91% of patients with preoperative plasma brain natriuretic peptide levels above 125.5pgmL-1 are at risk of developing low cardiac output syndrome which is an important postoperative outcome.

[Adding 75 mg pregabalin to analgesic regimen reduces pain scores and opioid consumption in adults following percutaneous nephrolithotomy].
Adding novel adjunctive drugs like gabapentinoids to multimodal analgesic regimen might be reasonable for lessening postoperative pain scores, total opioid consumption and side effects after percutaneous nephrolithotomy. We aimed to evaluate the effect of pregabalin on postoperative pain scores, analgesic consumption and renal functions expressed by creatinine clearance (CrCl) and blood neutrophil gelatinase-associated lipocalin (NGAL) and cystatin C (Cys C) levels in patients undergoing percutaneous nephrolithotomy (PCNL). ⋯ Oral single-dose preemptive 75 mg pregabalin was effective in reducing early postoperative pain scores and total analgesic consumption in patients undergoing PCNL without leading to hemodynamic instability and side effects.

[The impact of different antiepileptic drugs on the sedation of children during magnetic resonance imaging].
The induction and inhibition of cytochrome P450 isoenzymes by antiepileptic drugs lead to changes in the clearance of anesthetic drugs eliminated via hepatic metabolism. We investigated the duration of the sedation and additional anesthetic needs during magnetic resonance imaging in epileptic children receiving antiepileptic drugs that cause either enzyme induction or inhibition. ⋯ In epileptic children, the response variability to the initial sedative agents during the magnetic resonance imaging procedure resulting from the inhibition or induction of the cytochrome P450 isoenzymes by the antiepileptic drugs mandated the titration of anesthetic agents.

[Iliohypogastric/ilioinguinal nerve block in inguinal hernia repair for postoperative pain management: comparison of the anatomical landmark and ultrasound guided techniques].
The purpose of this study is to compare the efficacy of iliohypogastric/ilioinguinal nerve blocks performed with the ultrasound guided and the anatomical landmark techniques for postoperative pain management in cases of adult inguinal herniorrhaphy. ⋯ According to our study, US guided iliohypogastric/ilioinguinal nerve block in adult inguinal herniorrhaphies provides a more effective analgesia and higher satisfaction of analgesia than iliohypogastric/ilioinguinal nerve block with the anatomical landmark technique. Moreover, it may be suggested that the observation of anatomical structures with the US may increase the success of the block, and minimize the block-related complications.

[Comparison of metaraminol, phenylephrine and ephedrine in prophylaxis and treatment of hypotension in cesarean section under spinal anesthesia].
Maternal hypotension is a common complication after spinal anesthesia for cesarean section, with deleterious effects on the fetus and mother. Among the strategies aimed at minimizing the effects of hypotension, vasopressor administration is the most efficient. The aim of this study was to compare the efficacy of phenylephrine, metaraminol, and ephedrine in the prevention and treatment of hypotension after spinal anesthesia for cesarean section. ⋯ Rescue boluses were higher only in the ephedrine group compared to metaraminol group. The incidence of nausea and vomiting and fetal acidosis were greater in the ephedrine group. The three drugs were effective in preventing hypotension; however, fetal effects were more frequent in the ephedrine group, although transient.
