Randomized Controlled Trial Comparative Study Clinical Trial
Comparison study between reamed and unreamed nailing of closed femoral fractures.
Intramedullary nailing is an accepted procedures for femoral fractures gives uniformly good results. Various methods of intramedullary fixation have been practiced in the past. Recently intramedullary fixation without reaming has come into vogue. ⋯ In the reamed group however there were only delayed union (2/50) and all fractures eventually united without any implant failure. We conclude that closed, reamed, antegrade insertion of an intramedullary nail is the treatment of choice in femoral shaft fractures, especially those involving the distal 1/3. The unreamed procedure should be reserved for certain exceptions, such as in polytrauma, where a shorter operative time and less blood loss is desired.

A retrospective study was done on 56 patients treated with percutaneous pinning of displaced supracondylar fractures of the humerus in the Paediatrics Institute of Hospital Kuala Lumpur between November 1999 and October 2000, to ascertain whether there is any significance clinically in the stability of a crossed pinning medial compared with lateral pinning method. There was equal number of patients in each group (28 patients). The radiographs were evaluated for change in Baumann's angle and Lateral Humero-capitellar angle from immediate post-op until the last follow-up. ⋯ No vascular injury was noted. Two cases of superficial pin tract infection were present in each group. The lateral percutaneous pinning technique of displaced supracondylar fractures of the humerus therefore offers a viable alternative to the crossed pinning group as it offers the same stability without the incipient risk of iatrogenic ulnar nerve injury.

The results of a prospective study of 94 patients with history of ear, nose or aerodigestive tract foreign bodies were analysed. Sixty six to 94% of patients presented within 24 hours to a primary care doctor, 80 to 94% was referred to the ENT Department within 24 hours and 89 to 93% of patients had their foreign bodies removed within 24 hours. ⋯ Foreign bodies in the aerodigestive tract tend to present earlier and more promptly removed compared with ear and nose foreign bodies. There was a significantly higher proportion of foreign body in the right ear and nostril compared to the left.

The effects of 2% and 4% sevoflurane in oxygen and nitrous oxide for induction of anaesthesia in 60 unpremedicated elderly patients was compared to those obtained during an intravenous Thiopentone induction. Intravenous induction induced anaesthesia in 27 +/- 5 seconds, significantly faster than a 2% or 4% sevoflurane induction (109 +/- 36 and 71 +/- 24 seconds respectively). ⋯ Heart rate changes were minimal in all groups. We conclude that 2% or 4% sevoflurane offered suitable conditions for induction of anaesthesia in the elderly with minimal cardiovascular derangement.
