Endotracheal tube fixation time: a comparison of three fixation methods in a military field scenario.

INTRODUCTION: Endotracheal intubation is required in many emergency, trauma and prehospital scenarios. Endotracheal tube (ETT) fixation must be stable and quick to apply to enable rapid evacuation and patient transport. This study compares performance times of three common ETT securement techniques which are practical for out-of-hospital and combat scenarios. METHODS: We compared the time required by military medics to complete ETT fixation in three techniques-fixation of a wide gauze roll wrapped twice around the head and tied twice around the ETT (GR), using a Thomas Tube Holder (TH) and using a pre-tied non-adhesive tape (PT). 300 military medics were randomised to apply one technique each on a manikin, and time to completion was recorded. RESULTS: 300 ETTs were successfully fixated by 300 military medics. Median times to complete ETT fixation by PT and TH techniques were 24 s (IQR (19 to 31) and (IQR 20 to 33), respectively). Both were significantly shorter to apply than the GR technique, with a median time of 57 s (IQR 47 to 81), p<0.001. CONCLUSIONS: In time critical situations such as combat, severe trauma, mass casualties and whenever rapid evacuation might improve the clinical outcome, using a faster fixation technique such as Thomas Tube Holder or a pre-tied non-adhesive tape might enable faster evacuation than the use of traditional endotracheal tube fixation techniques.

Intercostal chest drain fixation strength: comparison of techniques and sutures.

OBJECTIVE: The accidental removal of an intercostal chest drain (ICD) is common and may result in serious complications. A number of fixation techniques and suture material are in use, and the selection is often based on personal preferences and equipment availability. This study is designed to determine which of the common techniques provides the strongest ICD fixation. METHODS: This study compared the mechanical strength of eight different ICD fixation techniques (purse string, 'Roman sandal', 'Jo'burg' (JO) technique, a suture through the tube, one and two passes through a locking plastic tie, tape fixation and a commercial disposable drainage tube holder) and two silk suture sizes using porcine cadavers and a digital push-pull dynamometer to simulate accidental removal of an ICD. A total of 14 different experimental set-ups produced 280 measurements. RESULTS: Significant differences in ICD fixation strength were observed. A modified JO technique using a size 1 silk suture was nearly three times stronger than a purse-string fixation using a size 0 silk and 10 times stronger from a commercial, adhesive-based device (180, 70 and 22, respectively). CONCLUSION: In situations where the mechanical strength of ICD fixation is important, using a size 1 silk and a modified JO technique may provide the strongest fixation.

Vascular injury following accidental intra-arterial injection of clindamycin: adverse drug reaction report.

Clindamycin in a commonly used antibiotic, considered safe for oral, intravenous and intra-arterial use. We present a case of a patient that received an inadvertent injection clindamycin 600 mg in 4 mL through a radial arterial line. The patient presented signs and symptoms of vascular occlusion and despite aggressive pharmacological and medical treatment developed massive and severe tissue injury.
