Randomized Controlled Trial Comparative Study Clinical TrialA comparison of two concentrations of bupivacaine and adrenaline with and without fentanyl in paediatric inguinal herniorrhaphy.
This study was designed to determine whether administration of caudal bupivacaine with fentanyl would have any effect on analgesia in paediatric patients undergoing inguinal herniorrhaphy repair. Fifty-six outpatient paediatric patients undergoing inguinal hernia repair were evaluated. Patients received, in a randomized manner, 1 ml.kg-1 of either bupivacaine 0.25% or 0.125% with or without fentanyl 1 microg.kg-1. ⋯ The 0.125% bupivacaine group had significantly more patients who received intravenous fentanyl in the PACU than did the other three groups (P<0.001). Increasing the concentration of bupivacaine from 0. 125% to 0.25% increased the incidence of postoperative vomiting. We recommend that clinicians utilize bupivacaine 0.125% with 1 microg. kg-1 fentanyl as the caudal injectate in paediatric patients undergoing inguinal hernia repair.

Randomized Controlled Trial Clinical TrialPostdural puncture headache is not an age-related symptom in children: a prospective, open-randomized, parallel group study comparing a22-gauge Quincke with a 22-gauge Whitacre needle.
Many reports have shown a low incidence of postdural puncture headache (PDPH) and other complaints in young children. The objective of this open-randomized, prospective, parallel group study was to compare the use of a cutting point spinal needle (22-G Quincke) with a pencil point spinal needle (22-G Whitacre) in children. We studied the puncture characteristics, success rate and incidence of postpuncture complaints in 57 children, aged 8 months to 15 years, following 98 lumbar punctures (LP). ⋯ The incidence of PDPH was similar, 15% in the Quincke group and 9% in the Whitacre group (P=0.42). The risk of developing a PDPH was not dependent on the age (r < 0.00, P=0.67). Eight of the 11 PDPHs developed in children younger than 10 years, the youngest being 23-months-old.

Randomized Controlled Trial Clinical TrialLaryngeal mask airway use in children with acute burns: intraoperative airway management.
Paediatric patients with acute burns often require many operative procedures in short succession; yet due to inhalation injury or recent extubation their airways may be susceptible to tracheal tube induced damage. We proposed the laryngeal mask airway (LMA) as a useful airway management tool in this setting. In this prospective study, 80 eight (88) patients with mean age (+/- SD) of 7.8 +/- 4.7 years and average percentage total body surface area burned (%TBSA) of 21 +/- 18% had their airways managed with an LMA while in the operating room for 141 procedures. ⋯ The other 10 events include arterial desaturation (n = 3), partial laryngospasm (5), airway obstruction (1) and regurgitation without aspiration (1). In each case, corrective action led to resolution of the problem with no patient morbidity. This series demonstrates the LMA is a safe and efficacious airway management device in the paediatric burn population.

Comparative Study Clinical TrialComparison of endtidal CO2 and arterial blood gas analysis in paediatric patients undergoing controlled ventilation with a laryngeal mask or a face mask.
Endtidal CO2 (PECO2) and arterial blood gas tensions were compared between laryngeal mask (LMA) and face mask (FM) ventilation in paediatric outpatients. Following premedication with midazolam, anaesthesia was induced with either thiopentone or isoflurane and atracurium. Anaesthesia was maintained with N2O, O2 and isoflurane. ⋯ The mean PaCO2 values in the FM group were 41.3+/-8.1 and 43.4+/-8.9 mmHg; and PaCO2 -PECO2 were 5.3+/-3.6 and 8.8+/-7.0 mmHg, respectively. These values were lower in the LMA group (P< 0.05). We have concluded that monitoring of PECO2 is more reliable for estimating blood gas values during controlled ventilation with a LMA than a face mask.
