Re-intubation and re-operation may occasionally be required after neuromuscular block (NMB) reversal. This study evaluated block onset times of a second dose of rocuronium (1.2 mg kg(-1)) after sugammadex reversal of rocuronium 0.6 mg kg(-1). ⋯ Rapid re-onset of NMB occurred after repeat dose of rocuronium 1.2 mg kg(-1) as early as 5 min after sugammadex in healthy volunteers. Re-onset of block took longer if second rocuronium dose was <25 min after sugammadex. The duration of action of second rocuronium dose increased with later repeat dose time points.

Effect of dexamethasone in combination with caudal analgesia on postoperative pain control in day-case paediatric orchiopexy.
Dexamethasone has a powerful anti-inflammatory action and has demonstrated reduced morbidity after surgery. The aim of this study was to examine the effects of a single i.v. dose of dexamethasone in combination with caudal block on postoperative analgesia in children. ⋯ Intravenous dexamethasone 0.5 mg kg(-1) in combination with a caudal block augmented the intensity and duration of postoperative analgesia without adverse effects in children undergoing day-case paediatric orchiopexy.

It is controversial as to whether T-wave elevation is caused by local anaesthetics, epinephrine, or their combination. It has been shown that T-elevation after intravascular injection of a small bupivacaine test dose is caused by epinephrine and not by bupivacaine. The aim of this study was to investigate ECG changes with higher doses of i.v. bupivacaine. ⋯ Higher doses of i.v. infused bupivacaine can cause T-elevation. With slower injection technique, T-elevation can already be detected at lower bupivacaine doses administered.
