Lymphedema is characterized by swelling, typically in the arms or legs, that occurs when the lymphatic system cannot adequately drain fluid from the tissues. Managing this condition relies heavily on compression therapy, which applies external pressure to the affected limb to help move accumulated fluid and prevent its return. The duration lymphedema wraps must be worn depends entirely on the phase of the comprehensive treatment plan: the initial intensive phase aimed at volume reduction or the long-term maintenance phase.
Duration During the Initial Decongestive Phase
The most intensive period of compression is during the initial phase of treatment, formally known as Complete Decongestive Therapy (CDT) Phase I. This phase is designed to achieve the maximum possible reduction in the limb’s size and fluid volume. The compression wraps are required to be worn continuously for approximately 23 to 24 hours per day.
The intensive phase typically lasts between two and four weeks, but can be extended depending on the severity of the swelling and the limb’s response to treatment. The goal of near-constant wear is to prevent the re-accumulation of lymph fluid between daily therapy sessions. Without this continuous pressure, the fluid would rapidly return, undermining the progress made during manual lymphatic drainage and exercise.
The wraps used in this phase are a multi-layer system constructed primarily with short-stretch bandages. This material offers a high working pressure when the patient moves their limb, acting like a pump to push fluid out. This is distinct from standard elastic bandages, which stretch significantly and can create a constricting effect detrimental to lymphatic flow.
When the limb is at rest, short-stretch bandages exert a low resting pressure, making them safe for 24-hour wear. The layers are applied with a pressure gradient, meaning the tightest application is at the hand or foot, and the pressure gradually lessens up the limb. This gradient assists in directing the fluid back toward the center of the body for drainage, which is crucial for achieving the volume reduction defining Phase I success.
Maintenance Phase Schedules and Alternatives
Once the limb volume has been reduced and stabilized, the patient transitions into the maintenance phase (CDT Phase II). This phase shifts away from continuous multi-layer bandaging toward a more flexible schedule using specialized compression garments. The primary goal is to maintain the reduction achieved in Phase I and prevent the limb from swelling again.
During the day, the wraps are replaced entirely by custom-fitted, high-pressure compression garments, such as sleeves or stockings. These garments are worn for all waking hours to support the tissues and control fluid accumulation. Garments are preferred for daytime wear due to their reduced bulk, which allows for greater freedom of movement and easier integration into daily activities.
The need for high-level compression continues overnight, requiring a new approach. Nighttime compression is managed by transitioning back to bandaging or using specific alternatives. These alternatives include specialized foam-lined nighttime garments or adjustable compression wraps, which use hook-and-loop closures for easy self-application.
Nighttime compression typically lasts eight to twelve hours, covering the entire time the patient is resting or sleeping. The non-elastic materials in nighttime systems are better suited to continue softening tissue and preventing fluid return while the limb is inactive. The exact schedule is highly individualized, making the maintenance phase a life-long, daily commitment to self-management.
Required Breaks for Skin Care and Hygiene
Even during the intensive 24-hour wear period of the initial decongestive phase, the lymphedema wraps must be removed daily for a short, mandatory break. This brief interruption is necessary to uphold meticulous skin care and hygiene, a foundational element of lymphedema management. The wraps are typically removed for a window of 30 to 60 minutes, which is just enough time to complete the necessary hygiene routine.
The skin must be thoroughly cleansed, dried completely, and moisturized with a low-pH lotion to prevent dryness and cracking. Breaks in the skin’s barrier create an entry point for bacteria, significantly increasing the risk of cellulitis. Therefore, the break is used to inspect the entire limb closely for any signs of irritation or skin breakdown before the wraps are reapplied.
Wraps must also be removed immediately if they cause symptoms indicating a problem with circulation or nerve function. Patients are instructed to take the wraps off if they experience pain, numbness, tingling, or noticeable color changes in the fingers or toes. These symptoms suggest the pressure is too tight or unevenly applied, requiring immediate correction by the patient or a lymphedema therapist.
