Forgotten guidewire: A case report

Introduction

The Seldinger technique for implanting central venous catheters is the most used in the world. A metallic guidewire is employed in it, introduced through the lumen of a venipuncture needle, which serves as a path for the introduction of the central venous catheter. Complications directly related to this technique are of several types, such an insertion of a long-winded segment of the guidewire, which can lead to venous perforation, cardiac perforation, arrhythmias or even guidewire retention/embolization.

Presentation of the case

We report the case of a patient with a late diagnosis of a guidewire retained in her venous system. The distal end of the guidewire pierced the pulmonary artery, crossed the chest wall and remained in the left breast tissue. It was removed by laparotomy, through an extra-peritoneal access to the right common iliac vein.

Discussion

Different factors have been identified as responsible for the increase in the number of guidewires retained after central venous catheterizations. Lack of supervision, in procedures performed by training physicians, has been identified as one of the most important risk factor in the cases reported in the literature.

Conclusion

The present report demonstrates that central venous catheterization, despite being a relatively straight forward procedure, should not be underestimated and should be performed by properly trained physicians or by training physicians under supervision.

•

Retained guidewire is a rare complication.

•

There are several factors for guidewire migration.

•

Central venous catheterization should not be underestimated.

Predictive capacity of prognostic scores for kidney injury, dialysis, and death in intensive care units

OBJECTIVE

To assess the capacity of Charlson, SAPS 3 and SOFA scores to predict acute kidney injury, need for dialysis, and death in intensive care unit patients.

METHOD

Prospective cohort, with 432 individuals admitted to four intensive care units. Clinical characteristics at admission, severity profile, and intensity of care were analyzed using association and correlation tests. The scores sensitivity and specificity were assessed using the ROC curve.

RESULTS

The results show that patients with acute kidney injury were older (65[27] years vs. 60[25] years, p = 0.019) and mostly are from the emergency department (57.9% vs. 38.0 %, p < 0.001), when compared to those in the group without acute kidney injury. For dialysis prediction, the results of SAPS 3 and SOFA were AUC: 0.590; 95%CI: 0.507-0.674; p-value: 0.032 and AUC: 0.667; 95%CI: 0.591-0.743; p-value: 0.000, respectively. All scores performed well for death.

CONCLUSION

The prognostic scores showed good capacity to predict acute kidney injury, dialysis, and death. Charlson Comorbidity Index showed good predictive capacity for acute kidney injury and death; however, it did not perform well for the need for dialysis.
