Design of personalized nasal catheter fixation device based on laser engraving technology and evaluation of its application effect

Abstract

Abstract Background: A historical controlled study method to compare the effectiveness of laser engraved personalized nasal cannula fixation devices with conventional cut nasal patches for fixing nasogastric tubes after esophageal cancer surgery. Methods: One hundred and twenty-four patients with indwelling nasal catheters for esophageal cancer surgery in a tertiary care hospital in Lanzhou were selected as study subjects and divided into control and observation groups according to the historical control study method, with 62 patients in each group. The control group used conventionally cut nasal patches to fix the nasal ducts, and the observation group used laser-engraved personalized nasal patches to fix the nasal ducts. The rate of catheter displacement or slippage under the fixation device, the number of rolled edges and replacement of nasal patches, nasal medical device related pressure injury and pre-injury condition, medical adhesive related skin injury, and patient comfort condition were observed in both groups. Results: The rate of nasal catheter displacement in the observation group was lower than that in the control group (P < 0.05). The number of rolled edges and replacement of nasal patches in the observation group were lower than those in the control group (P < 0.05). The incidence of nasal mucosal indentation, nasal pain, and medical adhesive-related skin lesions in the observation group was lower than that in the control group (P < 0.05). The physiological level of comfort of patients in the observation group was better than that in the control group (P < 0.05). Conclusion: Laser engraved personalized nasal cannula fixation devices have better clinical value than conventional cut nasal patches. It can reduce the incidence of clinical nasal catheter displacement, the frequency of rolled edges and replacement of nasal patches, reduce the incidence of nasal medical device related pressure injuries and medical adhesive related skin injuries, and increase patient comfort.
