Comportamiento del dolor fantasma en pacientes amputados en Cárdenas. Periodo 2015-2019 / Phantom pain behavior in amputated patients in Cardenas. Period 2015-2019

RESUMEN Introducción: la amputación es un procedimiento quirúrgico y la incapacidad como consecuencia se puede considerar una entidad clínica. Toda respuesta a la amputación es altamente individual. Entre el 40 y 80 % de los amputados manifiestan dolor de la zona amputada o dolor de miembro fantasma. Entre todos los problemas que se pueden presentar tras la cirugía este es uno de los más graves. Objetivo: determinar el comportamiento del dolor fantasma en la población amputada en Cárdenas y la mejoría clínica de los síntomas con los diferentes tratamientos. Periodo comprendido entre 1-1-2015 al 31-12-2019. Materiales y métodos: se realizó un estudio descriptivo de corte transversal en el Hospital General "Julio Miguel Aristegui Villamil" de Cárdenas, en el período comprendido del 1-1-2015 al 31-12-2019. Con el fin de evaluar las variables clínicas y demográficas de pacientes con antecedentes de amputación unilateral de miembro y que acudieron al cuerpo de guardia y/o consultas externas de Ortopedia y Traumatología, de Angiológica y Cirugía Vascular por presentar dolor fantasma. Resultados: con respecto a la mejoría de los síntomas y del propio dolor fantasma, según la escala de evaluación del dolor (EVA), se demostró que hubo alivio muy discreto y en un 96 % de los pacientes se presentó persistencia de los mismos. Conclusiones: los resultados fueron insatisfactorios, a pesar de los tratamientos utilizados en el estudio (AU).

ABSTRACT Introduction: amputation is a surgical procedure and disability as its consequence can be considered a clinical entity. Any response to amputation is highly individual. Between 40 and 80% of amputees refer pain in the amputated area or phantom limb pain, and among all the problems that can occur after surgery, this is one of the most serious. Objective: to determine the behavior of phantom pain in the amputated population in Cárdenas from January 1st 2015 to December 31st 2019 and the clinical improvement of symptoms with the different treatments applied. Materials and methods: a descriptive cross-sectional study was conducted in the General Hospital Julio Miguel Aristegui Villamil of Cárdenas in the period from January 1st 2015 to December 31st 2019, with the aim of evaluating the clinical and demographic variables of patients with antecedents of unilateral limb amputation who attended the emergency department or outpatient Orthopedics and Traumatology, and Angiology and Vascular Surgery consultations for presenting phantom pain. Results: regarding the improvement of the symptoms and the phantom pain itself, according to the pain evaluation scale (VAS), it was shown that there was very discreet relief and its persistence in 96% of the patients. Conclusions: unsatisfactory results are observed instead of the treatments used in the study (AU).

Pain management in new amputees: a nursing perspective.

Phantom limb pain (PLP) is a widespread and challenging neuropathic pain problem, occurring after both surgical and traumatic amputation of a limb. It may occur immediately after surgery or some months later, however, most cases it presents within the first 7 postoperative days. Patients report a range of pain characteristics in the absent limb, including burning, cramping, tingling and electric shock sensation. The incidence of PLP has been reported to be between 50% and 85% following amputation. Its management is notoriously difficult, with no clear consensus on optimal treatment. It is often resistant to classic balanced analgesia and typical neuropathic pain medications. Taking into account these issues, the authors aimed to improve the management of patients undergoing amputation at their institution, by ensuring accurate and holistic assessment, the selection of suitable interventions through critical analysis and synthesis of available evidence, and the appropriate evaluation and adaptation of treatment plans, to ensure patients achieved their individualised goals.

An observational descriptive study of the epidemiology and treatment of neuropathic pain in a UK general population.

BACKGROUND: This study updated our knowledge of UK primary care neuropathic pain incidence rates and prescribing practices. METHODS: Patients with a first diagnosis of post-herpetic neuralgia (PHN), painful diabetic neuropathy (PDN) or phantom limb pain (PLP) were identified from the General Practice Research Database (2006 - 2010) and incidence rates were calculated. Prescription records were searched for pain treatments from diagnosis of these conditions and the duration and daily dose estimated for first-line and subsequent treatment regimens. Recording of neuropathic back and post-operative pain was investigated. RESULTS: The study included 5,920 patients with PHN, 5,340 with PDN, and 185 with PLP. The incidence per 10,000 person-years was 3.4 (95% CI 3.4, 3.5) for PHN; and 0.11 (95% CI 0.09, 0.12) for PLP. Validation of the PDN case definition suggested that was not sensitive. Incident PHN increased over the study period. The most common first-line treatments were amitriptyline or gabapentin in the PDN and PLP cohorts, and amitriptyline or co-codamol (codeine-paracetamol) in PHN. Paracetamol, co-dydramol (paracetamol-dihydrocodeine) and capsaicin were also often prescribed in one or more condition. Most first-line treatments comprised only one therapeutic class. Use of antiepileptics licensed for neuropathic pain treatment had increased since 2002-2005. Amitriptyline was the only antidepressant prescribed commonly as a first-line treatment. CONCLUSION: The UK incidence of diagnosed PHN has increased with the incidence of back-pain and post-operative pain unclear. While use of licensed antiepileptics increased, prescribing of therapy with little evidence of efficacy in neuropathic pain is still common and consequently treatment was often not in-line with current guidance.

Factors affecting quality of life in lower limb amputees.

BACKGROUND: Quality of life (QoL) is increasingly being recognized as an important outcome for rehabilitation programs, and has mainly been used to compare the efficacy of interventions or to compare amputees with other diseased populations. There is relatively a limited number of studies primarily focusing on analyzing the multitude of factors influencing QoL in amputees. OBJECTIVES: To identify important background and amputation related factors which affect quality of life (QoL) in lower limb amputees, and to compare QoL profile of amputees' to that of general population. STUDY DESIGN: Cross-sectional. METHODS: Lower limb amputees 18 years and above from a rehabilitation centre, a limb-fitting centre and four limb-fitting camps were interviewed (n = 605). Structured questionnaires included patient background and amputation characteristics, and the MOS short-form health survey (SF-36) for assessing QoL. The SF-36 was administered to a general adult population using purposive sampling (n = 184). RESULTS: SF-36 PCS and MCS scores were found to be significantly lower for amputees when compared to those for the general population. In this study, employment status, use of an assistive device, use of a prosthesis, comorbidities, phantom-limb pain and residual stump pain were found to predict both PCS and MCS scores significantly, and explained 47.8% and 29.7% of variance respectively. Age and time since amputation accounted for an additional 3% of variance in PCS scores. CONCLUSIONS: The abovementioned factors should be addressed in order to ensure holistic reintegration and participation, and to enable the amputees to regain or maintain QoL. Prospective longitudinal studies are recommended to systematically study the change in QoL over time and to assess its determinants. CLINICAL RELEVANCE: Proper appraisal of abovementioned factors in the rehabilitation programme would assist in establishing a treatment protocol, which would adequately address QoL in amputees.

Pain management in the traumatic amputee.

Traumatic amputees may experience a variety of acute and chronic pain issues, including phantom limb pain and residual limb pain. Research continues to determine the causes of these problems and to find the most appropriate and effective treatments for each of these phenomena. It is important for health care providers to be knowledgeable about the variety of treatments available, including medications, surgical procedures, complementary and alternative therapies, and self-treatment methods to ensure that amputees receive the best practices for individualized, effective pain management that they deserve.

Phantom pain and sensation among British veteran amputees.

Using a mail-delivered questionnaire, we surveyed 590 veteran amputees concerning phantom pain, phantom sensation and stump pain. They were selected randomly from a population of 2974 veterans with long-standing limb amputation(s) using a computer random number generator. Eighty-nine percent responded and of these, 55% reported phantom limb pain and 56% stump pain. There was a strong correlation between phantom pain and phantom sensation. The intensity of phantom sensation was a significant predictor for the time course of phantom pain. In only 3% of phantom limb pain sufferers did the condition become worse. One hundred and forty-nine amputees reporting phantom pain discussed their pain with their family doctors; 49 were told that there was no treatment available. Transcutaneous electric nerve stimulation, analgesics and non-steroidal anti-inflammatory drugs were satisfactory methods for controlling phantom limb pain.

Phantom limb pain.

Phantom limb pain is a common sequel to amputation, whether traumatic or surgical. Provision of a pain-free interval before surgery is likely to reduce the incidence of the condition. The possible mechanisms of pain perception in an absent body part and the reasons for the frequent failure of conventional therapy are discussed here.

A survey of current phantom limb pain treatment in the United States.

A survey of phantom limb pain treatment methods currently used by Veterans Administration hospitals, medical schools, pain clinics, and pain specialists in the United States was carried out to determine which treatments are in use, their success rates as estimated by their users, and experience with unsuccessful treatment methods used by patients prior to referral to the respondent. The combined results of a recent literature search and this survey identified 68 treatment methods of which 50 were commented upon by the survey respondents as being in current use. Only a few treatment methods were even moderately successful when subjected to the criterion of low failure rates after one year. Non-surgical treatment methods were far more successful than surgical ones. A possible treatment regime based on optimizing moderately successful methods is proposed for further study.
