A NOVEL TECHNIQUE OF RYLE’S TUBE FIXATION (PARTHA’S TECHNIQUE) FOR CONVENIENT INTRAOPERATIVE USE

Abstract

Dear sir,

Nasogastric tube (Ryle’s tube) insertion is one of the commonest ward procedures done for different indications. During selected surgical procedures, the insertion of such tubes is done in the preoperative ward. There are lot of reported difficulties during insertion in the intraoperative period.¹ The Ryle’s tube is inserted in the classical manner but usually adjusted to enable the surgeon to do the gut surgery. The tube is usually fixed to the nose by a plaster wound round the tube. This technique is usually difficult to unwound if there is a need to reposition. In surgical and medical wards, the necessity for repositioning is not very significant. But during the intraoperative period, the surgeons always prefer to move the tube here and there to make the operative field better. This in turn causes much discomfort to the attending anaesthesiologist if the plaster is stuck in a traditional way.  Hence, we propose a novel technique of fixation wherein we get the advantages of avoiding accidental removal but with the ease of frequent positional adjustment. A sixty-five-year-old male came for upper Gastro-intestinal surgery. The Ryle’s tube was inserted in the ward and fixed as given in fig 1. To adjust the position after removal of the plaster becomes a herculean task. Its more difficult to adjust the plaster with gloved hands. The plaster was removed before induction and fixed as described below. The first plaster (P1 in fig 2) was vertical and fixed the tube to the nose in a vertical fashion. The portion of the plaster which sticks to the tube should be around 50 % of the plaster length. Usually there is a small gap between the attachment of the tube and the nose. The next or the second plaster (P2 in fig 2) was transverse which fixed the vertical plaster to the nose. The transverse plaster never touched the Ryle’s tube. (Fig 2) If we need to adjust the position, the plasters can be easily loosened to adjust and fix again. The portion of the plaster in the gap can be lifted to loosen. There is no need for changing the plasters. Many a time, the surgeons may ask for repeated changes of position during the surgery. Hence this Partha’s technique of fixation suits repeated unfastening and regluing. There are reports of lost Ryle’s tubes² after fixation in the wards. Lorente³ in his study of intensive care patients, found an incidence of accidental removal of Ryle’s tube as 4.48%. A single plaster use may be a cause of malposition. An extensive search of the literature did not reveal fixation techniques with their pros and cons. We have been using this technique for many years so far with minimal problems.  This report is limited to the fact that it is not used much with no comparative studies to know its advantages and disadvantages.
