Abstract. Summary: Background: This pilot study was set up to examine the effects of a continuous postoperative wound infusion system with a local anaesthetic on perioperative pain and the consumption of analgesics. Patients and methods: We included 42 patients in this prospective observational pilot study. Patients were divided into two groups. One group was treated in accordance with the WHO standard pain management protocol and in addition to that received a continuous local wound infusion treatment (Group 1). Group 2 was treated with analgesics in accordance with the WHO standard pain management protocol, exclusively. Results: The study demonstrated a significantly reduced postoperative VAS score for stump pain in Group 1 for the first 5 days. Furthermore, the intake of opiates was significantly reduced in Group 1 (day 1, Group 1: 42.1 vs. Group 2: 73.5, p = 0.010; day 2, Group 1: 27.7 vs. Group 2: 52.5, p = 0.012; day 3, Group 1: 23.9 vs. Group 2: 53.5, p = 0.002; day 4, Group 1: 15.7 vs. Group 2: 48.3, p = 0.003; day 5, Group 1 13.3 vs. Group 2: 49.9, p = 0.001). There were no significant differences between the two groups, neither in phantom pain intensity at discharge nor postoperative complications and death. Conclusions: Continuous postoperative wound infusion with a local anaesthetic in combination with a standard pain management protocol can reduce both stump pain and opiate intake in patients who have undergone transfemoral amputation. Phantom pain was not significantly affected.

Abstract Introduction Burns with upper extremity (UE) amputation present a unique rehabilitation challenge. The purpose of this study of UE amputees who are active prosthesis users was to compare outcomes for those with and without burns. Methods This is part of a larger nationwide study of U.S. military members and veterans with UE amputations. In-person data were collected at 5 sites. An therapist measured passive and active range of motion (PROM, AROM); administered the Quick Disability of the Arm, Shoulder, and Hand; Community Reintegration of Injured Service Members-Computer Adaptive-Test; Trinity Amputation and Prosthetic Experience Scale; health-related quality of life (VR-12); Activities Measure for Upper Extremity Amputees; Southampton Assessment Procedure; 9-Hole Peg Test; and Jebsen-Taylor Hand Function Test (JTHF); and recorded residual and phantom pain; timing of prosthesis receipt; and current prosthesis use. The IRB approved this study. Results Data were collected on 126 individuals with UE amputation, of whom 105 had data on etiology and were included. Of these, 13 (12.4%) had burns (B) vs non-burn (NB). The majority were unilateral amputees (69% B, 90% NB). Most were transradial (TR) amputees (B 84.6%, NB 66.3%) as opposed to transhumeral (TH). A minority received their prosthetics within the first 3 months post-amputation (11.1% B, 28.8% NB) (p=0.15). Average age was 57.6 (SD 15.6) years for NB and 53.0 (20.6) years for B. Mean time since amputation was 22.5 (18.0) years for NB and 25.2 (17.3) years for B. The following non-significant differences in outcomes between B and NB were observed. Thirty-nine percent of B were employed full-time vs 18.9% of NB (p=0.15). The primary prosthesis was, for NB, a body-powered prosthesis (66.7%); for B, myoelectric (50%) or body-powered (50%). For unilateral UE amputees, there were no differences between B and NB on performance testing for dexterity and functional tasks or in self-reported disability, quality of life or prevalence or intensity of pain. B trended towards more moderate to severe PROM deficits with shoulder forward flexion (TH B 50%, TH NB 23.1% [p=0.444]; TR B 20%, TR NB 5.6% [p=0.197]) and shoulder abduction (TH B 50%, TH NB 26.9% [p=0.497]; TR B 30%, TR NB 16.4% [p=0.376]). Also, TR amputees with burns trended towards more PROM deficits with elbow flexion (B 20%, NB 6.9% [p=0.212]) and elbow extension (B 20%, NB 8.6% [p=0.272]). AROM deficits also trended greater in B. Conclusions We did not observe differences in physical function, pain levels, or quality of life between those with and without burns. Further studies with larger samples are needed, to include analysis of burn location, burn size, hospital length of stay, and rehabilitation care.

Post Operative Pain

Breast cancer is a potentially deadly disease affecting one in eight women. With the trend toward minimally invasive therapies for breast cancer, such as breast conserving therapies, sentinel node biopsies, and early treatments of radiation and chemotherapy, life expectancy after breast cancer has increased. However, pain after breast cancer surgery is a major problem and women undergoing mastectomy and breast reconstruction experience postoperative pain syndromes in approximately one-half of all cases. Patients post mastectomy and breast reconstruction can suffer from acute nociceptive pain and chronic neuropathic pain syndromes. Several preventative measures to control acute post operative pain and chronic pain states such as post mastectomy pain and phantom pain have been tried. This review focuses on the recent research done to control acute and chronic pain in patients receiving minimally invasive therapies for breast cancer, such as breast conserving therapies of mastectomies and breast reconstruction, sentinel node biopsies, and early treatments of radiation and chemotherapy.

Psychological Mechanism

A number of writers have drawn attention to the importance of emotional factors in phantom limb pain (Kolb, 1950, 1952; Simmel, 1956; Russell, 1959; Von Hagen, 1963). Kolb (1950, 1952) reported an association between the discussion of certain emotionally loaded topics and accesses of pain in the phantom. Stengel (1965), in his Maudsley Lecture, discussed the role played in these experiences by the psychological mechanism of identification with others. He briefly referred to the patient whom we have studied.
