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.

Clinical TrialPostoperative extradural infusions in children: preliminary data from a comparison of bupivacaine/diamorphine with plain ropivacaine.
To try to decrease the incidence of side-effects associated with postoperative extradural infusions of local anaesthetics in combination with opioids, we have used plain ropivacaine solutions in 200 children. The first 72 children received an infusion of bupivacaine 0.125% + diamorphine 20 microg x ml-1, then 200 children received plain ropivacaine solutions. The children who received ropivacaine were found to have lower incidences of nausea, pruritus, urinary retention, and were less sedated, despite comparable analgesia. The management of plain ropivacaine for extradural analgesia is discussed.

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.

ReviewPaediatric head injury: incidence, aetiology and management.
Trauma is the commonest cause of hospital admission in children. Head injuries are present in 75% of children with trauma and 70% of all traumatic deaths are due to the head injury. ⋯ Therapeutic interventions will be discussed with specific emphasis on outcome studies. However, institution of adequate oxygen delivery and haemodynamic stability in the child at the earliest moment remains the most important aspect of the management plan.

Case ReportsManagement of difficult airways with a laryngeal mask airway under propofol anaesthesia.
We report four cases of difficult airway managed with a laryngeal mask airway (LMA) under propofol anaesthesia; this method was chosen to minimize psychological and physical trauma. Case 1 was a boy with dermatomyositis; Case 2, a girl wearing a base ring of a stereotactic frame; Case 3, a boy with Treacher-Collins syndrome; Case 4, a boy with Goldenhar syndrome. They were anaesthesized with propofol and though spontaneous ventilation became shallower, or apnoea occurred, the stimulus of inserting an LMA awakened the patient and caused more active spontaneous ventilation while a patent airway was established by the LMA. All tracheal intubations were performed smoothly and without delay through the LMA, and we believe that psychological and physical trauma was thus minimized.
