Anaesthesiologists need to know how to place vascular access. Often, anesthesiologists are referred to by other professionals. They are familiar with vascular access techniques, including advanced vascular access. It is stressful for children, their families, and caregivers to get vascular access. Children's anxiety and withdrawal are challenging for an anaesthesiologist. Intraosseous, arterial, and venous access are types of vascular access.
Veins are used for anaesthesia, resuscitation, fluids, and medications. During major surgery and for critically ill children, arterial access is good for blood pressure monitoring and blood gas sampling. When peri-arrest or arrested, intraosseous access may be needed.

Children's veins can be tricky to access while awake. Distraction techniques should be tailored to the child's age. Sucking, swaddling, and rocking are also beneficial to babies and toddlers. Prilox® is a local anaesthesia cream with lignocaine, prilocaine, or tetracaine. Sucrose reduces pain in neonates. Anaesthesia or sedation is required for central venous access. Vascular access requires clean, healthy skin.
For peripheral venous cannulations, secure clean gloves, but for arterial, central, and long-term veins, take aseptic precautions. Monitoring complications with transparent non-occlusive dressings over vascular cannulation. A chlorhexidine-impregnated dressing is better for long dwells. For most patients, antibiotics aren't necessary except for patients with implantable ports and immunocompromised patients.
Devices and aids for placing vascular access
A DIVA score can help predict the difficulty of venous access in children, and appropriate aids or devices can be used for cannulation. Peripheral venous access can be made easier by using simple techniques like tourniquets, tapping over veins, and warming the area. Epidermal nitroglycerin can also dilate local vessels, especially after local anaesthetic cream's vasoconstricting effects.
In children under 2 years of age, light passes through thin connective tissues, which allows it to pass through the thin connective tissues to highlight the veins, which makes placing peripheral venous cannulas a lot easier. It is possible to identify superficial veins with near-infrared devices, which can be difficult to detect with regular light or to palpate with regular hands. Light-emitting diodes have better transillumination power and lower burn risk.
Due to the fact that haemoglobin in blood absorbs infrared light, veins can be seen in the dark. There are so many different types of devices out there that it is hard to tell which one is the best one. Despite a systematic review and meta-analysis, it has been concluded that near-infrared light devices are most useful in vascular access situations where access is difficult.
Ultrasound can be used for peripheral, central, and arterial vascular access. Ultrasound requires training and competency. In ultrasound-guided vascular access, ultrasound is recommended not only for placing catheters but also for choosing the appropriate catheter size, verifying catheter tip placement, and detecting complications associated with catheters. Real-time visualisation during placement is improved with echogenic needles. Performing vascular cannulation with an oblique-axis view is more successful and less likely to involve mechanical complications.
Radiological confirmation of catheter direction and tip position is desirable for all central venous accesses. Fluoroscopy is recommended when implantable ports, tunnelled catheters, or PICCs are used long-term. Book an appointment at Manipal Hospitals to know more about the treatment facilities.
Access to paediatric arteries can be difficult. Lack of vascular access should not delay or deny treatment. Anaesthesiologists should learn about various types of vascular access. Lives can be saved by choosing the right vascular access.
