Pain and cognitive status in the institutionalized elderly: perceptions & interventions.

The purposes of this study were to examine the relationship between: (1) nurses' ratings of pain and corresponding administration of pain medication to elderly long-term care residents, and (2) cognitive status of the elderly and pain medication orders/administration. Participants were 83 residents, 60 years of age and older, in two groups: cognitively impaired (n = 64), and cognitively intact (n = 19). For comparison purposes, 19 of the cognitively impaired subjects were matched on age and diagnosis to provide control for potentially painful conditions. A retrospective medication review of the resident's charts was conducted to compare medication orders and administration on analgesics that were scheduled and p.r.n. (given as needed). The pain ratings of 25 RNs using a visual analogue scale were correlated with pain medications given to the resident on the day of the rating. Results indicated that RNs' ratings of resident pain and the administration of pain medications were not significantly correlated. In addition, cognitively impaired residents were prescribed significantly less scheduled medication and received significantly less pain medication (either p.r.n. or scheduled) than the cognitively intact elderly. Implications for practice and research are discussed.

Preemptive analgesia in the laparoscopic patient.

One hundred consecutive laparoscopic patients were prospectively followed in the Post-anesthesia Recovery Unit (PAR) in a community hospital. Data was collected regarding (1) intraoperative administration of ketorolac, (2) instillation of local anesthesia into the wound, and (3) requirements for analgesic administration in the PAR. Those patients receiving both forms of preemptive analgesia required less narcotic administration in the PAR. The results were highly significant. Based on these data and the observance of markedly reduced pain in patients during the early postoperative period, an institutional plan of care was developed which has resulted in the virtual elimination of the need to administer narcotics to patients undergoing routine laparoscopic surgical procedures. The resultant plan of care, which includes preemptive analgesia, rapid ambulation, early feeding, and routine timed administration of non-narcotic pain medications, is presented. Data is also presented which demonstrates a more rapid discharge of patients from the hospital.

Partial meniscectomy and osteoarthritis. Implications for treatment of athletes.

The biphasic ultrastructure of the meniscus and of articular cartilage provides their function in the complex biomechanics of the knee joint including load distribution, shock absorption, viscoelasticity, a smooth low friction gliding surface and resilience to compression. Meniscectomy may lead to destruction of cartilage and to osteoarthritis of the knee joint. Osteoarthritic changes after meniscectomy have been reported in up to 89% of patients. Retrospective analysis after open or arthroscopically assisted meniscectomy revealed restriction in sports to be between 2 and 50% and cessation of sports to be between 2 and 25%. Generally, patients with degenerative changes at the time of surgery are reported to have lower knee joint function and to resume sports activities later. Pharmalogical measures to treat osteoarthritis following previous meniscectomy include pain medication and intra-articular drug administration. Additionally, range of motion and strengthening exercises and moderate athletic activities are recommended. When surgery is considered, correctional osteomies and unicompartmental or total knee arthroplasty depending on the degree of osteoarthritis are preferred.

Emergency Providers' Pain Management in Patients Transferred to Intensive Care Unit for Urgent Surgical Interventions.

IntroductionPain is the most common complaint for an emergency department (ED) visit, but ED pain management is poor. Reasons for poor pain management include providers’ concerns for drug-seeking behaviors and perceptions of patients’ complaints. Patients who had objective findings of long bone fractures were more likely to receive pain medication than those who did not, despite pain complaints. We hypothesized that patients who were interhospital-transferred from an ED to an intensive care unit (ICU) for urgent surgical interventions would display objective pathology for pain and thus receive adequate pain management at ED departure.MethodsThis was a retrospective study at a single, quaternary referral, academic medical center. We included non-trauma adult ED patients who were interhospital-transferred and underwent operative interventions within 12 hours of ICU arrival between July 2013 and June 2014. Patients who had incomplete ED records, required invasive mechanical ventilation, or had no pain throughout their ED stay were excluded. Primary outcome was the percentage of patients at ED departure achieving adequate pain control of ≤ 50% of triage level. We performed multivariable logistic regression to assess association between demographic and clinical variables with inadequate pain control.ResultsWe included 112 patients from 39 different EDs who met inclusion criteria. Mean pain score at triage and ED departure was 8 (standard deviation 8 and 5 [3]), respectively. Median of total morphine equivalent unit (MEU) was 7.5 [5–13] and MEU/kg total body weight (TBW) was 0.09 [0.05–0.16] MEU/kg, with median number of pain medication administration of 2 [1–3] doses. Time interval from triage to first narcotic dose was 61 (35–177) minutes. Overall, only 38% of patients achieved adequate pain control. Among different variables, only total MEU/kg was associated with significant lower risk of inadequate pain control at ED departure (adjusted odds ratio = 0.22; 95% confidence interval = 0.05–0.92, p = 0.037).ConclusionPain control among a group of interhospital-transferred patients requiring urgent operative interventions, was inadequate. Neither demographic nor clinical factors, except MEU/kg TBW, were shown to associate with poor pain management at ED departure. Emergency providers should consider more effective strategies, such as multimodal analgesia, to improve pain management in this group of patients.

Report of two cases

Two patients underwent thoracotomy for resection of pulmonary or esophageal carcinoma. Postoperatively, epidural catheters were inserted for pain management. Complaints of severe injection pain over the abdomen or lower extremities were made during one administration of pain medication. Progressive weakness and numbness developed over the lower trunk and lower extremities, with subsequent respiratory difficulties. Potassium chloride (KCl) was suspected to have been mistaken for normal saline as the diluent for morphine. In addition to endotracheal intubation and ventilatory support, steroids were administered both intravenously and epidurally to suppress spinal cord irritation. The two patients regain motor and sensory functions 14 and 18 hours later, respectively, without sequelae.

Ethical Issues in Pain Management at Home

This review of several studies from the authors' program of research supports the notion that the experience of pain, particularly in the home, has a profound effect not only on the patient, but on family and health care providers as well. Family caregivers revealed their private grief and burden when describing the physical suffering they witnessed. They faced the daily responsibility of making decisions regarding a loved one's pain, and the decisions often resulted in ethical conflicts. Caregivers generally felt ill-prepared for the administration of pain medication. They struggled to balance the need for medications to relieve pain against the perceived unwanted side effects and fear of addiction. These studies also demonstrate that a concerted effort must be made by health care providers to support the pain management role of family caregivers. By listening, being available, making pain management a priority, and reinforcing appropriate pain management principles, health care professionals help sustain family caregivers in carrying out their anguishing and unrelenting task.

Insertion of Groshong Central Venous Catheters Utilizing Fluoroscopic Techniques

Groshong central line indwelling catheters are extensively used in gynecologic oncology patients for administration of chemotherapy, intravenous fluids, and pain medications. They are easy to maintain and have a good safety record. We report on the placement of these central venous catheters under direct fluoroscopic visualization as a method which is safe, inexpensive, and efficacious in high-risk patients. Fluoroscopic visualization during insertion provides several advantages: visualization of bony landmarks, placement of the guidewire into the subclavian vein and superior vena cava under direct visualization, and confirmation of appropriate distal placement of the Groshong catheter. Patient advantages include the following: (1) avoidance of unnecessary punctures to access the subclavian vein; (2) verification of guidewire placement to avoid cephalic placement; (3) passage of the guidewire only as far as the right atrium to avoid potential dysrrhythmias secondary to right ventricular irritation; and (4) a savings of approximately 60% over insertion in the general operating room. Thirty patients had placement under fluoroscopic visualization in the angiography suite of Georgetown University Hospital. The average age of the patients was 58 years (42-78). Sixteen patients had ovarian cancer, 6 had endometrial cancer, 5 had cervical cancer, and 3 had other gynecologic malignancies. Fifteen patients had catheters placed for chemotherapy, 14 for hydration, and 1 for pain control. Ten patients had had previous central venous catheters: 6 had been removed for infection, 2 for thrombus, 1 for completion of chemotherapy, and 1 for catheter kinkage. All 10 with previous catheters had successful placement of catheters in the angiography suite. Complications from insertion were minimal with one asymptomatic pneumothorax and one proximal port in an extravascular position. We present the technique of fluoroscopic insertion of Groshong catheters which is an effective method of placement in high-risk patients.

Instruction in the techniques and concept of supportive care in oncology.

Cancer education merits a coordinated, vertical curriculum and an integrated planning strategy. It has become clear that it is as important to teach the techniques of supportive care in oncology as it is to teach the concepts of cancer biology, pathology, epidemiology, prevention, detection and aggressive treatments. Our aim is to determine whether the medical school and nursing school curricula give the students an introduction to the concepts of supportive care of the cancer patient. The spectrum of such supportive care encompasses a wide range of issues working towards a common goal of providing overall comfort with an emphasis on quality of life, and runs parallel with specific therapeutic strategies and associated problems. Do the graduate medical student and nursing student understand that cancer management is multidisciplinary and team-based? That the approach to pain management not only includes the administration of pain medications, but should also evaluate pain assessment and anesthetic, neurosurgical and behavioral approaches? That nausea and vomiting associated with chemotherapy can be ameliorated to a certain extent? That infections are common but algorithms exist for prevention and therapy? That certain metabolic complications are unique to cancer patients? That transfusions are vital procedures in patients with neoplasms undergoing aggressive treatments but are associated with certain risks and complications? That there are serious psychosocial, ethical and legal needs to be considered? To address these issues, the American Cancer Society Professors of Clinical Oncology, the American Cancer Society Professors of Oncology Nursing and the United States Cancer Center Directors were surveyed.(ABSTRACT TRUNCATED AT 250 WORDS)

Treatment of snakebite poisoning

The epidemiology, mechanics, prevention, pharmacology, clinical manifestations, and treatment of snakebites are reviewed. Poisonous snakes bite approximately 8000 persons annually in the United States, causing approximately 12-15 deaths per year. Pit vipers (rattlesnakes, copperheads, cottonmouths, and massasaugas) are responsible for 99% of all snakebite poisonings; coral snakes and other foreign exotic species are responsible for the additional 1%. Envenomation is characterized by pain, edema, and ecchymoses at or near the site of venom injection, followed by cardiac, hematologic, neurologic, renal, and pulmonary toxicity. The major clinical finding in most snakebite poisonings is local tissue necrosis. Immediate treatment for snakebite includes limiting movement and placing a constriction band proximal to the site of venom injection. If medical care is more than 30 minutes away, the wound may be incised and suctioned. Antivenin therapy is the mainstay of medical treatment of snakebite, along with administration of plasma expanders, pain medication, diazepam, tetanus toxoid, antiseptics, and antibiotics. Patients who have pain, swelling, ecchymoses, systemic symptoms, or abnormal laboratory findings within 30 minutes to one hour of a bite are probable candidates to receive antivenin therapy. Before receiving antivenin therapy, the patient must be tested for hypersensitivity to the antivenin. Antivenin therapy is most effective when given within four hours of the snakebite. Pharmacists--especially those serving rural areas--should be familiar with current snakebite treatments, both local and systemic, and should be prepared to provide important information and dispel any myths about snakebite poisoning.

Clinical Application of a Patient-controlled Apparatus for Ventricular Administration of Morphine in Intractable Pain: Report of 28 Cases

Abstract The authors developed a patient-controlled apparatus (L-224) for ventricular administration of pain-relieving medication and utilized it in the treatment of 28 patients with intractable pain. The initial dose of morphine hydrochloride was 1 mg, which afforded pain relief for an average of 170 hours. At an average dose of 1.8 mg, the average time of pain relief obtained was 137 hours. Therefore, they conclude that L-224 is a satisfactory apparatus for the ventricular administration of pain medication; it is patient controlled, safe, and reliable in clinical application.

Pediatric nurses: the assessment and control of pain in preverbal infants.

Pediatric nurses practicing in a children's hospital participated in this exploratory study investigating nurses' attitudes regarding postoperative pain in infants, including recognition of pain cues and strategies for pain management. Three instruments developed by us were used to obtain data: the Pain Questionnaire, a demographic and attitudinal profile; a self-directed videotape; and the Videotape Questionnaire, an interactive tool to obtain participant responses to videotaped vignettes of infants recovering from surgery. Three independent variables yielded significant results: critical care versus noncritical care nurses, agreement versus disagreement to administer pain medication to infants expected to have pain but not exhibiting pain behaviors, and classes on pediatric versus adult/pediatric pain since licensure. Noncritical care nurses, nurses agreeing to administer pain medication, and nurses attending pediatric pain classes recognized a greater number of cues on videotaped vignettes. Nurses attending pediatric pain classes administered more narcotics. Noncritical care nurses rated the pain experienced by the infants in the vignettes to be more severe compared with ratings made by critical care nurses.

The influence of gender on the frequency of pain and sedative medication administered to postoperative patients

This study examines whether the frequency of pain and sedative medication administered to postoperative coronary artery bypass graft (CABG) patients differs according to patient gender. It was hypothesized that nurses medicate patients with pain medication more frequently if they are men than if they are women. It was also hypothesized that nurses medicate female patients with sedative medication more frequently than male patients. The hypotheses in this study were based on a review of the literature indicating that health care professionals hold stereotypic views of women as emotionally labile and more apt to exaggerate complaints of pain than men. The medication records of 30 male and 30 female patients between 44–71 years of age, who had undergone recent CABG surgery, were evaluated in this study. Male and female patients were matched on the basis of age, number of grafts completed in surgery, and location of graft donor sites. All data were obtained through the use of medical records to allow for control of patients' current and past medical history. The frequency of pain and sedative medication administered to these patients from 12 hours postop to 72 hours postop was compared. The results revealed that male patients were administered pain medication significantly more frequently than female patients, and that female patients were administered sedative medication significantly more frequently than male patients. Also, patients 61 years or younger received pain medication significantly more frequently than those patients 62 years and over.

Use of infusion devices for epidural or intrathecal administration of spinal opioids

The use of infusion devices for epidural or intrathecal administration of spinal opioids is described. The risks of infection and mechanical catheter complications, the need for escalating doses, reservoir volume, drug stability, and cost are practical considerations associated with use of both external and internal infusion systems. Use of patient criteria to identify suitable candidates for intraspinal administration of pain medication helps ensure successful management. The criteria for intraspinal delivery pumps are safety, accuracy, reliability, ease of management by the patient and the health-care professional, and compatibility of the drug with the pump components. The primary factors to consider when comparing pumps to be used for intraspinal delivery of pain medication are the volume and flow rate requirements of the devices. External portable infusion devices are classified according to the mechanism of operation into three primary groups: syringe pumps, peristaltic mechanisms, and elastomeric reservoir pumps. Portable patient-controlled analgesia pumps that have syringes, flexible reservoir bags, and elastomeric reservoirs have been developed. Implanted systems with flow rates that are preset at the factory make pain management more difficult when the patient requires changes or escalations in doses over time. A programmable implanted pump is available. Two advantages of continuous epidural or intrathecal infusion are (1) the peaks and valleys of pain relief with bolus injections are eliminated and (2) the need for multiple injections is reduced. Patient-controlled analgesia (PCA) pumps enhance the efficacy of continuous infusions by allowing the patient to administer bolus doses to control acute pain.

Pain Control in the Terminally Ill Child at Home

The seriously ill or terminally ill child with cancer has received inadequate pain control in the past, partly due to physicians' and nurses' fears and misconceptions regarding the administration of effective pain medications to a child. Advances in assessment techniques in the infant and young child, as well as increasing use of pain assessment questionnaires and VAS in the older child, have mandated changes in administration of analgesia to children. It is the responsibility of the health-care team of provide adequate pain control to the ill child, using knowledgeable assessment and monitoring skills. The goal of therapy for the dying child is to maintain comfort and support the child and the family. Providing analgesia in the hospital or the home has proven safe and effective when administered either orally or parenterally, and comfort of the child is achieved.

Major Ambulatory Surgery of the Plastic Surgical Patient

In the final analysis, a patient who does not require any more in the way of postoperative nursing care than bed rest and administration of food, water, and pain medication should be able to have surgery in an outpatient facility as safely and successfully as in an inpatient facility. A large general plastic surgery practice in an ambulatory surgical center creates unique problems, but most of these problems are solvable and have not prevented most plastic surgeons from conducting an ever increasing volume of their work in the ambulatory setting.

Respiratory Disease of Sheep and Goats

Recently, the French National Institute for Agricultural Research appointed an expert committee to review the issue of pain in food-producing farm animals. To minimise pain, the authors developed a ‘3S’ approach accounting for ‘Suppress, Substitute and Soothe’ by analogy with the ‘3Rs’ approach of ‘Reduction, Refinement and Replacement’ applied in the context of animal experimentation. Thus, when addressing the matter of pain, the following steps and solutions could be assessed, in the light of their feasibility (technical constraints, logistics and regulations), acceptability (societal and financial aspects) and availability. The first solution is to suppress any source of pain that brings no obvious advantage to the animals or the producers, as well as sources of pain for which potential benefits are largely exceeded by the negative effects. For instance, tail docking of cattle has recently been eliminated. Genetic selection on the basis of resistance criteria (as e.g. for lameness in cattle and poultry) or reduction of undesirable traits (e.g. boar taint in pigs) may also reduce painful conditions or procedures. The second solution is to substitute a technique causing pain by another less-painful method. For example, if dehorning cattle is unavoidable, it is preferable to perform it at a very young age, cauterising the horn bud. Animal management and constraint systems should be designed to reduce the risk for injury and bruising. Lastly, in situations where pain is known to be present, because of animal management procedures such as dehorning or castration, or because of pathology, for example lameness, systemic or local pharmacological treatments should be used to soothe pain. These treatments should take into account the duration of pain, which, in the case of some management procedures or diseases, may persist for longer periods. The administration of pain medication may require the intervention of veterinarians, but exemptions exist where breeders are allowed to use local anaesthesia (e.g. castration and dehorning in Switzerland). Extension of such exemptions, national or European legislation on pain management, or the introduction of animal welfare codes by retailers into their meat products may help further developments. In addition, veterinarians and farmers should be given the necessary tools and information to take into account animal pain in their management decisions.
