Conditions

Peripheral IV cannula (PIV) insertion

Interventions

Practitioners, both nurses and physicians from any specialism or medical department, who were familiar with the study protocol, routinely obtained the peripheral intravenous access. A peripheral intra

Eligibility

Inclusion criteria

Inclusion criteria: All patients were adults, regardless their American Society of Anesthesiology (ASA) physical status, demographics, and medical history.

Exclusion criteria

Exclusion criteria: Patients were excluded if they did not understand or answer the questionnaire (due to physical or communicational disorders) or were unresponsive, when intravenous access had been gained already, and because of protocol violations.

Design outcomes

Primary

Measure	Time frame
The primary outcome variable was defined as failed peripheral intravenous cannulation on the first attempt. Peripheral intravenous cannulation was defined successful, if the practitioner was able to inject a saline flush without signs of infiltration. We determined an attempt as one percutaneous needle puncture, regardless the amount of subcutaneous exploration from the single puncture site. After a failed attempt, a new attempt was stated to be any change in localizing a vein, followed by a new percutaneous puncture.	—

Secondary

Measure	Time frame
Baseline demographic data (sex, ASA physical status, age, weight, length, body mass index, whether or not the patient fastened for at least six hours, weeks of gestation, and whether or not the patient was signed up for planned surgery) and patients medical history (chronic diseases, intravenous drug abuse, alcohol abuse, smoking, vessel diseases, a history of chemotherapy treatment, hematological status, the use of medications, and hypovolemia based on hemodialysis or dehydration) were provided by our local institutional clinical registry, which collects information in a computerized database. Procedure related data (patient’s dominant side, received premedication, skin shade classified on a three-point scale based on race and origin, diameter of the vein measured in millimeters after applying a tourniquet, whether or not the vein could be identified by palpating and/ or visualizing the upper extremity, if it was difficult to achieve an intravenous access in the past, size of the intravenous catheter, side of cannulation, place of cannulation on the extremity, pain score after cannulation on an eleven-points NRS scale, number of attempts needed for successful intravenous cannulation, and the years of experience of the physician) were prospectively collected by the attending physician and registered on specific forms. Furthermore, the full medical records of the eligible patients were reviewed in order to determine risk factors for a difficult intravenous access. The risk score for a failed first attempt upon insertion of an intravenous catheter was calculated for each patient prior to the procedure with the A-DIVA scale.	—
