Complications in the use of peripherally inserted central catheter associated with peripheral intravenous therapy: retrospective cohort.

Objective: to analyze the occurrence of difficulty in the peripheral insertion of the central catheter and the presence of complications in the use of this device in hospitalized adults who received peripheral intravenous therapy through a short peripheral intravenous catheter and to identify whether there is an association between peripheral intravenous therapy and the presence of complications in the use of the peripherally inserted central catheter.

Method: retrospective cohort, with patients aged 18 years or over, in a tertiary teaching hospital, with a peripherally inserted central catheter, who had at least one previous short peripheral intravenous catheter. Data were analyzed using descriptive statistics and Poisson regression.

Results: the sample consisted of 76 patients. There was an association between difficulty in the insertion procedure and number of punctures (p<0.01) and insertion in the external jugular vein compared to the upper limbs (p<0.01). The insertion site was also associated with the removal of the peripherally inserted central catheter due to complications in the robust analysis of variance (p=0.02). No associations were identified between: difficulty inserting the device and time on peripheral intravenous therapy (crude model p=0.23; adjusted model p=0.21); difficulty in insertion with administration of irritating and vesicant medication (crude model p=0.69; adjusted model p=0.53); complication in the use of peripherally inserted central catheter and time of peripheral intravenous therapy (crude and adjusted models p=0.08); and secondary migration of the catheter tip with the device insertion site (p=0.24).

Conclusion: it was possible to identify secondary migration as one of the main complications, resulting in premature removal of the device. Furthermore, the greater the number of puncture attempts to insert the PICC, the greater the difficulty in inserting it. Insertion into the external jugular vein was recurrent, with a higher risk of removal due to complications in relation to the upper limbs.
