[Comparison of an oxygen-conserving module "Oxytron" and the reservoir cannula "Oxymizer Pendant" with continuous oxygen administration via nasal prong in hypoxemic patients].

High costs involved in administering continuous long-term oxygen therapy to patients with chronic lung diseases and limited portability of oxygen sources stimulated research into and development of oxygen conserving devices. Oxytron (Weinmann, Hamburg) is a new electronic demand oxygen delivery system which limits oxygen flow to the early phase of inspiration. The reservoir cannula Oxymizer Pendant (Chad-Therapeutics Inc.) is a nasal prong system incorporating a pendant reservoir which stores oxygen during expiration and delivers it as a bolus at the onset of inspiration. Ten patients with significant hypoxaemia at rest received oxygen delivered at various breath interval settings with the Oxytron method and at flow rates of 2, 3 and 41/min with the reservoir cannula Oxymizer Pendant and with continuous flow. The results indicate that significantly less oxygen was required to provide equivalent oxygen saturation with Oxytron as compared with steady flow delivery: an oxygen flow reduction of greater than 75% was achieved at all Oxytron settings tested. With the reservoir cannula oxygen saving was most evident at low oxygen flows: 29.3, 19.4 and 4.7% less oxygen was required than with continuous flow at 2, 3 and 41/min. Individual patient acceptance of various drug delivery systems and response to therapy should be considered when prescribing home oxygen therapy. The use of oxygen saving techniques could result in a substantial cost saving and greater mobility may help to improve compliance in patients requiring continuous oxygen therapy.

Difficult intubations.

Six cases of difficult intubation are presented and their management discussed. Routine practice of blind nasal intubation and fiberoptic laryngoscopy is recommended for improved dexterity. Elective tracheostomy should be considered in cases where the airway is compromised and cricothyroidotomy should be recommended.

The treatment of severe pancreatic pain.

The management of four patients with severe pancreatic pain is discussed. Bilateral coeliac plexus block with alcohol gave effective pain relief to the three patients with pancreatic carcinoma and the one patient with acute pancreatitis. The treatment of the pain of acute and chronic pancreatitis is reviewed.
