Subcutaneous infiltration of fluids in large volumes has become essential for a wide variety of plastic surgery procedures [4]. Many surgeons regard preoperative infiltration of the surgical field with solutions containing vasoconstrictors and local anesthetics as an indispensable step. Besides liposuction using the tumescent technique and procedures such as breast reduction, face-lift, and abdominoplasty often benefit from the bloodless operating field provided by preoperative infiltration. The necessary amount of solution to be infiltrated can be as large as several liters, and it is cumbersome for both the surgeon and the medical team to prepare and infiltrate such large volumes. Various infiltration systems are avaliable on the market, but their high cost precludes their wide use. Additionally, the use of motorized infiltration pumps for officebased procedures are not cost effective in most instances. Several authors addressed this issue previously in the context of tumescent infiltration for liposuction, proposing various designs as substitutes for infiltration pumps. However, a wound irrigation system [1], an arthroscopy set [2], a micromotor irrigation system [5], or a Jet Lavage System [3] is not avaliable in every setting, and some of these methods might be unsuitable for use in more delicate areas such as the face. We introduce a practical, low-cost setup for infiltration of large volumes. A three-way stopcock is positioned between the infiltration needle and a syringe, and an infusion set is connected to the stopcock (Fig. 1). By rotating the handle of the three-way stopcock, the syringe can be filled, with the solution coming through the infusion set. By rotating the handle again, the connection between the syringe and infusion set is blocked, and the solution can be injected. A longer needle or a larger syringe can be used if desired. With this simple method, the clinician can avoid changing syringes for refills and save time.
