¿Cuánto tiempo debe permanecer un stent traqueal implantado? Curación de la estenosis luego de 10, 16 y 22 años de implante / How Long Should a Tracheal Stent Remain Implanted? Healing of Stenosis 10, 16, and 22 Years After Implantation

Tres stents traqueales fueron removidos luego de 10, 16 y 22 años, a lo que le siguió la correspondiente curación de la estenosis traqueal. Se reportan dos nuevos casos de estenosis traqueal benigna, tratados con prótesis de silicona, que se presentaron a control luego de muy largas ausencias: 16 años en uno y 22 en otro. Se suman a un caso anteriormente publicado y curado luego de 10 años de permanencia del stent, que también presentó una amplia y estable luz traqueal luego la remoción. Se describen los hallazgos endoscópicos, y se incluyen reflexiones sobre la curación de la estenosis observada en todos ellos y su probable relación con el largo tiempo de permanencia de las prótesis. Se investigan las propiedades físicas de los stents, luego de tan prolongado lapso de implante y se las compara con un dispositivo nuevo. Se emite una propuesta que podría conducir a la curación de las estenosis traqueales con tratamiento endoscópico y stent por tiempo prolongado.

Three tracheal stents were removed after 10, 16, and 22 years, followed by healing of tracheal stenosis. Two new cases of benign tracheal stenosis are reported, treated with silicone pros theses, which presented for follow-up after very long absences: 16 years in one case and 22 years in the other. They add to a previously published case that was healed 10 years after the stent was implanted, which also had a wide and stable tracheal lumen after removal. The endoscopic findings are described, and reflections are included on the healing of the observed stenosis in all cases and its probable relationship with the prolonged indwelling of the prostheses. The physical properties of the stents are inves tigated after such a long period since implantation, and they are compared with a new device. A proposal is put forward that could lead to the healing of tracheal stenosis with endoscopic treatment and prolonged indwelling of the stent.

Open versus closed peripheral intravenous catheters in neonates: a prospective comparative study

Background: Open peripheral intravenous (IV) catheters have been routinely used in neonates. Closed catheters have resulted in a longer indwelling time and reduction in catheter related complications such as phlebitis in adults. However, there is paucity of data in neonates.Methods: We conducted this pilot study in a pre-post study design. Open catheters were used in the first phase and closed catheters in the second phase. Hundred babies requiring intravenous fluid therapy for at least 24 hours in this neonatal intensive care unit were included in each group. Indwelling time and the complications leading to removal of the catheter were compared between the two groups.Results: Both groups were comparable in terms of gestational age, day of life, site of cannulation, nature of intravenous fluid and drugs administered. In the open catheter group, there was significant increase in use of inotropes (38% vs 22%; p=0.014) and blood products (16% vs 5%; p=0.011). The mean indwelling time (hours) was significantly greater in closed catheter group compared to open catheter group (47.1'19.4 vs 38.04'17.9; p <0.008). Inotrope use was found to decrease the indwelling time. There was an increase in indwelling time by 8.2 (SE 2.67) hours even after adjusting for use of inotropes. The incidence of catheter related complications was similar in both groups.Conclusions: There is a marginal but statistically significant increase in indwelling time when closed peripheral IV catheters are used in neonates. However, our results would be more meaningful if replicated in a larger randomized controlled trial.

Evaluation on effect of improved sterilized transparent dressing on indwelling status of indwelling needle / 重庆医学

Objective To conduct the contrastive analysis on the indwelling time of fixing indwelling needle by cutting sterile transparent dressing and non-cutting sterile transparent dressing.Methods A total of 236 inpatients in this hospital from August to December 2016 were selected.The patients with odd at last number of admission number served as the experimental group (119 cases),while the patients with even at the last number of admission number served as the control group(117 cases).The indwelling needle type was 18GA,the puncture was once success and the fluid infusion course was more than 5 d.The experimental group used the cutting sterile transparent dressing for fixing the indwelling needle and the extension tube vas completely exposed to the outside of dressing,while the control group adopted the conventional indwelling needle application fixation mode.The blood returning plugging pipe rate,average indwelling time and phlebitis occurrence at 24,48,72,96,＞ 96 h after indwelling needle were recorded.Results The blood returning plugging tube situation at 48,72,96,＞96 h after indwelling needle in the experimental group was superior to that in the control group,the difference was statistically significant(P＜0.05);the average indwelling time in the experimental group was (72.12 ± 3.25)h,while which in the control group was (59.34--3.78) h,and the difference was statistically significant (P＜0.05).Seven cases of phlebitis occurred in the experimental group and 9 cases in the control group,the difference was not statistically significant(P＞0.05).Conclusion Applying cutting sterile transparent dressing for fixing the indwelling needle reduces the plugging pipe rate due to returning blood coagulation,extends the indwelling needle use time,increase the patient's satisfaction,moreover does not increase the phlebitis occurrence risk.

Effect of indwelling time of lacrimal silicone drainage tube on patients with chronic dacryocystitis and its influence on patients' vision / 国际眼科杂志(Guoji Yanke Zazhi)

AIM: To investigate the effect of indwelling time of lacrimal silicone drainage tube on chronic dacryocystitis and its effect on visual acuity.?METHODS: The clinical data of 92 patients ( 110 eyes ) with chronic dacryocystitis treated with lacrimal drainage tube in our hospital from January 2013 to December 2016 were retrospectively analyzed. According to the indwelling time, the patients were divided into 6wk group (42 patients 50 eyes ) and 12wk group ( 50 patients 60 eyes). Comparison of two groups on clinical efficacy, vision, overflow symptoms, complications and recurrence was taken.?RESULTS:The effective rate was significantly higher in the 6wk group than in the 12wk group (P<0. 05). The visual acuity and incidence of epilepsy symptoms at 3mo after extubation was not signifcantly different (P<0. 05). The incidence of complication was 14. 0％ (7/50) at 3mo after extubation in 6wk group and significantly lower than that in the 12wk group which was 38. 3％ (23/60, P<0. 05). The recurrence rate was 2. 0％ (1/50) in the 6wk group, which was significantly lower than that in the 12wk group (18. 3％, 11/60;P<0. 05).?CONCLUSION: The clinical efficacy of lacrimal silicone drainage tube for 6wk and 12wk is similar to patients with chronic dacryocystitis. There is also little difference in the visual acuity of patients with dacryocystitis, but with the prolongation of the lacrimal duct drainage tube, rinse patency rate, increase the difficulty of extubation, complications and recurrence rate, the clinical situation should be based on the patient as much as possible to shorten the lacrimal duct silicone drainage tube retention time.
