Clinicians hesitate to perform thoracic paravertebral blockade (TPVB) in children due to the potential high risk of adverse effects. No paediatric anatomical guidelines for TPVB exist. This study aimed to estimate the appropriate depth and distance for safe needle positioning in children. ⋯ These anatomical guidelines for TPVB are recommended to help prevent anaesthetic complications such as pneumothorax, when ultrasonography and CT are unavailable.

Randomized Controlled Trial
Addition of adrenaline to chloroprocaine provides a moderate duration time for epidural anaesthesia in elective caesarean section.
Epidural anaesthesia using chloroprocaine with or without adrenaline and lidocaine with adrenaline were compared. ⋯ Epidural anaesthesia using chloroprocaine with adrenaline has a quick onset and moderate duration and is an attractive alternative to lidocaine and adrenaline or chloroprocaine alone for caesarean section.

Randomized Controlled Trial Comparative Study
Optimal bent length of lightwand for intubation in adults: a randomized, prospective, comparative study.
To evaluate the effect on intubation success of different bent lengths of a lightwand (a malleable illuminating stylet used for intubation), based on the patient's thyroid prominence-to-mandibular angle distance (TMD), thyroid prominence-to-incisor distance (TID) and gender. ⋯ Gender-determined bent length was more suitable for lightwand-guided intubation than TID or TMD. For most patients, the optimal bent length was in the range of 6.0-6.9 cm.

Randomized Controlled Trial
Randomized prospective study of olecranon fracture fixation: cable pin system versus tension band wiring.
This prospective, randomized study compared the effectiveness of the cable pin system (CPS) versus tension band wiring (TBW) for olecranon fracture fixation. ⋯ Internal fixation by CPS is an effective method for olecranon fracture and is associated with a shorter healing time, fewer complications and better function than TBW.

Randomized Controlled Trial Comparative Study
Comparison of the optimal effect-site concentrations of remifentanil for preventing cough during emergence from desflurane or sevoflurane anaesthesia.
To compare the effect-site concentrations of remifentanil target-controlled infusion (TCI) that produced 50% and 95% of the maximal effect (EC50 and EC95, respectively) for preventing cough during emergence from desflurane or sevoflurane anaesthesia, in patients undergoing elective thyroidectomy. ⋯ During emergence from anaesthesia, variations in effect-site concentrations of remifentanil for preventing cough are of limited importance as they do not generate significant differences in results.
