Evaluation of the efficiency of heat and moisture exchangers during paediatric anaesthesia.
This study evaluates the efficiency of heat and moisture exchangers (HMEs) in allowing adequate humidification and warming during anaesthesia in children. Eighteen paediatric patients undergoing anaesthesia were divided into two groups: group A ten patients: infants up to 10 kg-->Hygrobaby HME; group B 8 patients: children above 10 kg-->Hygroboy HME. The following parameters were evaluated: body temperature (bT), room temperature (rT), fresh gas temperature, HME warm-up time, inspired and expired gases temperature and humidity, conserving efficiency, and duration of anaesthesia. ⋯ The conserving efficiency was good (0.93 in both groups). A positive correlation was found between efficiency and fresh gas temperature. HMEs did not meet the minimum standards for humidity and heating during anaesthesia in children, although their conserving efficiency was found to be satisfactory.

Postal survey of the anaesthetic techniques used for paediatric tonsillectomy surgery.
A postal survey of anaesthetic techniques used for tonsillectomy surgery in children (age 3-16 years) was performed with particular reference to the use of the reinforced laryngeal mask airway and the use of suxamethonium. From 110 questionnaires despatched, replies were obtained from 88 consultant anaesthetists with commitments to otolaryngologic (ENT) anaesthesia (response rate 80%). ⋯ Suxamethonium was used routinely by 40 consultants (45%) for tonsillectomy surgery. Severe problems with its use had been encountered by 26 (30%) respondents

A new modification of anaesthesia mask for fibreoptic intubation in children.
We made a paediatric anaesthesia mask suitable for fibreoptic intubation by modifying a commercially available disposable mask with a ventilation port (Vent port) on a side. We added a large fibreoptic port (FO port, 22 mm in ID) in the middle of the mask to allow the passage of all sizes of paediatric tracheal tubes. ⋯ We succeeded in tracheal intubation in several infants and children with difficult airway in less than ten min, mainly via the nasotracheal route. This fibreoptic mask provides a safer technique for fibreoptic intubation in patients with difficult airways, especially in infants and small children.

Case ReportsThe epidural dorsomedian septum as a possible cause for unilateral anaesthesia in an infant.
Unilateral epidural anaesthesia occurring in an infant is reported. An epidurogram revealed the presence of a midline structure suggestive of the dorsomedian septum. Epidural anatomy is reviewed and implications for threading epidural catheters in infants are discussed.

Case ReportsCan a dose of 2microg.kg(-1) caudal clonidine cause respiratory depression in neonates?
A case of multiple life-threatening postoperative apnoeas in a term neonate undergoing inguinal herniorrhaphy and orchidopexy who received light inhalation anaesthesia combined with caudal block with 1 ml.kg-1 ropivacaine 0.2% plus 2 microg.kg-1 clonidine is reported. The patient showed no apparent risk factors for postanaesthetic apnoea. Oxycardiorespirography five days after surgery only showed minor abnormalities. Clonidine though administered caudally in the usual dose of 2 microg.kg-1 appeared to be the most likely cause for postanaesthetic apnoea in this neonate.
