Study of oral negative pressure for clinical prevention of upper limb lymphedema and subcutaneous seroma after breast cancer surgery

Objective: To study the effection of the establishment of oral negative pressure for clinical prevention and treatment of upper limb lymphedema and subcutaneous fluid after breast cancer surgery.Methods: Established oral negative pressure for 30 test group patients,compared the incidence of upper limb lymphedema and subcutaneous fluid collection,and the time of drainage tube completely removed with control group patients.Results: The incidence of upper limb lymphedema was 10%(3/30) in experimental group patients with 33.3%(10/30) in control group of patients(χ2=4.812,P0.05).The time of drainage tube completely removed was shorter in experimental group(χ2=16.530,P0.05).There was no increase of the incidence subcutaneous fluid collection in experimental group(χ2=1.298,P0.05).Conclusion: The establishment of oral negative pressure provides a new way of thinking and methods for clinical prevention and treatment of upper limb lymphedema and subcutaneous seroma after breast cancer surgery.
