Venous cannulation is needed for the management of nearly all patients, as such the need to have a good venous access cannot be overemphasized. However, sometimes, peripheral venous cannulations can prove to be very difficult and even nearly impossible. Multiple failed attempts to venous cannulation can cause delays in patient care, and many attempts have been made to reduce failed venous cannulation.
Various methods have been suggested, and many devices have been used to assist for venous cannulation.,,, These include gentle slapping of the skin overlying the vein, using venous tourniquet, using warm compresses, transillumination, ultrasound, etc. We present a novel application of mobile phones in helping us in cannulation of patients with difficult veins.
After dimming the lights for better visualization, the flashlight of mobile phone is turned on and kept in close contact with the arm to be cannulated. It is then scanned across arm's width for the presence of veins. Veins appear as dark cords while rest of the soft tissue appears as reddish regions [Figure 1]. After scanning the course of veins, an appropriate site for venous cannulation can be decided and cannulation done [Video 1].
This method helps due to transillumination of veins. There are commercial instruments that work on the same principle of illumination, but they are costly and not widely available. The purpose of writing this letter is to sensitize others of a novel application of a device which today all of us have.
Cai et al. using a similar method had used torch pens to facilitate venous cannulation in their patients (also based on transillumination) and found the method to be effective. We advise cleaning mobile phones with spirit before and after coming in contact with the patient. Further, it helps if the flashlight of the mobile is situated toward the periphery of mobile as it then provides better illumination.
Regarding other methods of securing venous cannulation, the use of a proximal venous tourniquet is a very commonly used modality. However, prolonged application of a venous tourniquet is said to increase venous tortuosity and fragility. Wiping the skin with alcohol is also said to improve visualization of veins.
Stolz et al. reviewed the use of ultrasound in aiding venous cannulation and concluded that ultrasound improved success rates when compared to traditional methods of intravenous cannulation in patients with difficult peripheral venous access. However, there was no effect on time to successful cannulaton or number of punctures required for successful cannulaton. Further, ultrasound is not available in many patient-care settings and not everyone is skilled in using it.
We do admit that this method does not provide us information about the depth of the vein from the skin surface and there is a learning curve associated with learning of this method. In addition, the ability of transillumination to visualize deeper veins has also been criticized. However, in many patients, it can save many pricks to the patients and anxiety to the treating physician in case of difficult cannulations.
