The use of single-use devices in anaesthesia: balancing the risks to patient safety.
Single-use devices are designed, manufactured and sold to be used once and then discarded. This paper addresses growing concerns about the quality of some devices. ⋯ Interview data suggests that when choosing to use a single-use device, clinicians balance concerns about the risk of infection against those about the risk of injury. However, despite reservations about induced harm and the unknown risk of an iatrogenic disease, most clinicians would want single-use devices used on themselves and their family if they were patients.

We report the first known case of acute upper and lower airway obstruction due to retropharyngeal haemorrhage secondary to acquired haemophilia A. The patient required tracheal intubation and ventilation followed by surgical tracheostomy, prior to transfer to the intensive care unit for management of her coagulopathy with recombinant clotting factor products under the care of the haematologists.

Randomized Controlled Trial Comparative Study
Bilateral intra-oral, infra-orbital nerve block for postoperative analgesia following cleft lip repair in paediatric patients: comparison of bupivacaine vs bupivacaine-pethidine combination.
This prospective, randomised, double blind study compared the efficacy of pethidine as an adjuvant to bupivacaine with the efficacy of bupivacaine alone for infra-orbital nerve block in alleviating postoperative pain in children undergoing cleft lip repair. Forty paediatric patients aged between 5 and 60 months undergoing cleft lip repair were randomly allocated to two groups of 20. ⋯ The median (IQR) duration of analgesia from the time of administration of block in group B was 18 h (14.2-20) compared to 29.1 h (24-36) in group P (p = 0.001). Addition of pethidine as an adjunct to local anaesthetic significantly prolonged the duration of postoperative analgesia without any adverse effects.

Randomized Controlled Trial Comparative Study
Comparison of the analgesic efficacy and respiratory effects of morphine, tramadol and codeine after craniotomy.
Pain after craniotomy remains a significant problem. The effect of morphine and tramadol patient-controlled analgesia (PCA) on arterial carbon dioxide tension is unknown in patients having such surgery. Sixty craniotomy patients were randomly allocated to receive morphine PCA, tramadol PCA or codeine phosphate 60 mg intramuscularly. ⋯ Morphine produced significantly better analgesia than tramadol at all time points (p < 0.005) and better analgesia than codeine at 4, 12 and 18 h. Patients were more satisfied with morphine than with codeine or tramadol (p < 0.001). Vomiting and retching occurred in 50% of patients with tramadol, compared with 20% with morphine and 29% with codeine.
