Diagnostic and therapeutic pathway for pain in a Continuing Care setting: a survey at an Italian Continuing Care Service.

Background: Law no. 38 of 15 March 2010 ensures and governs the access to the palliative care and pain management network for patients who require it. The professional roles involved in the project have been identified by the law, with the specific experience and expertise in the field of palliative care and pain management, by allocating a meaningful role to general practitioners (GPs). For this reason, an important direct training plan has been drawn up that GPs can count on for dedicated refresher courses to increase and deepen their knowledge in this specific clinical field. If the role of the GPs in the pain management and palliative care network was well-defined by the law, we cannot say the same for the Continuing Care Physician (CCP), a role that only partially overlaps that of the GP. The study observed the response of a Continuing Care Service (CCS) to the demand for services from patients with pain-related problems. The role of the CCP is, therefore, outlined in the pain therapy care network by observing the services provided to patients experiencing pain that is understood as being a non-deferrable problem. Methods: A survey was conducted at the CCSs site in Aquila, AS-01 Abruzzo. For this reason, the attending physician records the data of patients who consult the CCSs for pain-related problems on an appropriate questionnaire. The survey period covered a total of 68 days (1 January - 8 March 2020). Results. One hundred sixty five sheets were completed; females were more represented than males (57.6% v 42.4%) and the 36-65 age group appears most greatly represented (47.9%). One of the most frequent reasons for consulting the service is "musculoskeletal pain" (58.2%), followed by abdominal pain (15.8%). In the majority of patients, pain lasted from days (53.9%), with an average of approximately 3 days (3.1± 2.9), or hours in 40% of cases, with an average of over 6 hours (6.54±3.1). 88.5% of patients defined the level of pain experienced as "severe" (NRS=7-10), and the intensity of the pain associated with its repetitiveness (80.3% vs 92.6%) as "severe", with a statistically significant difference in relation to nonrepetitiveness cases (p=0.02). 66.1% of patients said that they had taken analgesics independently, with nonsteroidal anti-inflammatory drugs (NSAIDs) the most frequently taken (53.5%). Patients who turned to the CCS received a pharmacological prescription in almost all cases. NSAIDs, specifically, were the most prescribed medicines (64.8%), followed by muscle relaxants (29.7%). Tramadol was the most represented among opioids, which was prescribed in 7.9% of cases. Just 6.1% of patients were entered into the regional pain management network. Conclusions: The results of the survey show that a large number of patients turn to the CCS to resolve painful symptoms of various natures. The study offers some food for thought concerning the role of CCPs and the importance of providing for their inclusion in the pain therapy clinical and training pathways provided for by Law 38/2010. This would ensure its more effective implementation and, therefore, better care for patients experiencing painful pathologies.

Care strategies and therapeutic pathways for chronic pain patients in Abruzzo Region, Italy.

BACKGROUND: Chronic pain is considered to be among the most disabling and costly diseases in North America, Europe and Australia. A large survey was conducted on chronic pain in Europe, called Pain in Europe. Italy ranks third in Europe in terms of prevalence, with 26% of the population suffering from chronic pain at some point. In 2010 Italy passed Law 38/2010, to ensure treatment for pain control in patients with oncological diseases as well as in patients with chronic non-cancer pain through a network of care services. This study aims to provide preliminary information regarding the application of L.38/2010 in the Abruzzo region of Italy. METHODS: A descriptive study was conducted on a non-probabilistic sample of people who attended pain therapy centres of the local health service in 2014. The patients (129) were interviewed by centre staff using a validated questionnaire. Recruitment was carried out by enrolling consecutive cases over a three-month period (February to April). RESULTS: Almost two-thirds of the patients had visited several physicians before requesting help. The initial visit to the pain therapy centre was made after some months in 37.2% of cases, and in 38% of patients it was made years after the onset of pain. The reasons given for this long wait before seeking specialist medical treatment for chronic pain reveal a wait-and-see attitude on the part of patients, who controlled their pain by taking painkillers. Responsibility for this delay in requesting assistance can however also be attributed 'externally' to the fact that patients were not aware that this kind of centre was available. CONCLUSION: The results of the study describe, in a regional context, a situation in which L.38/2010 is hard to apply. The study showed how the care pathway for these patients is still characterised by difficulty in accessing the network of local services. Clearly, more effort needs to be directed towards an effective application of L.38/2010, with increased availability of resources to develop and strengthen the network of services at regional level.

Italian Intersociety Recommendations on pain management in the emergency setting (SIAARTI, SIMEU, SIS 118, AISD, SIARED, SICUT, IRC).

BACKGRAUND: Pain is the primary reason for admission to the Emergency Department (ED). However, the management of pain in this setting is often inadequate because of opiophagia, fear of excessive sedation, and fear of compromising an adequate clinical assessment. METHODS: An intersociety consensus conference was held in 2010 on the assessment and treatment of pain in the emergency setting. This report is the Italian Intersociety recommendations on pain management in the emergency department setting. RESULTS: The list of level A recommendations includes: 1) use of IV acetaminophen for opioid sparing properties and reduction of opioid related adverse events; 2) ketamine-midazolam combination preferred over fentanyl-midazolam fentanyl-propofol in pediatric patients; 3) boluses of ketamine IV (particularly in the population under the age of 2 years and over the age of 13) can lead to impairment of the upper airways, including the onset of laryngospasm, requiring specific expertise and skills for administration; 4) the use of ketamine increases the potential risk of psychomotor agitation, which can happen in up to 30% of adult patients (this peculiar side effect can be significantly reduced by concomitant systemic use of benzodiazepines); 5) for shoulder dislocations and fractures of the upper limbs, the performance of brachial plexus block reduces the time spent in ED compared to sedation; 6) pain relief and the use of opioids in patients with acute abdominal pain do not increase the risk of error in the diagnostic and therapeutic pathway in adults; 7) in newborns, the administration of sucrose reduces behavioural responses to blood sampling from a heel puncture; 8) in newborns, breastfeeding or formula feeding during the procedure reduces the measures of distress; 9) in pediatric patients, non-pharmacological techniques such as distraction, hypnosis and cognitive-behavioural interventions reduce procedural pain caused by the use of needles; 10) in pediatric patients, preventive application of eutectic mixtures of prilocaine and lidocaine allows arterial and venous samples to be taken in optimum conditions; 11) in pediatric patients, the combination of hypnotics (midazolam) and N2O is effective for procedural pain, but may be accompanied by loss of consciousness. CONCLUSION: The diagnostic-therapeutic pathway of pain management in emergency should be implemented, through further interdisciplinary trials, in order to improve the EBM level of specific guidelines.

Anaesthesia management in patients with multiple chemical sensitivity syndrome.

Multiple Chemical Sensitivity (MCS) is characterised by the appearance of numerous and sometimes severe symptoms, when subjects are in contact with various chemicals and medicinal substances. Currently there are no useful guidelines for managing clinical issues and, specifically, anaesthesia for patients with MCS. This case report describes anaesthesia management in a patient affected by clinically documented MCS and a latex allergy, a candidate for a laparoscopic cholecystectomy operation.

Hydromorphone does not influence the immune response in patients affected by chronic pain.

Hydromorphone (HMP) is a semisynthetic opioid that has been widely used over many years in the treatment of chronic moderatesevere pain. A number of studies have demonstrated the use of HMP in patients with cancer pain as safe and affective, and more recently HMP has been also utilised in the treatment of chronic degenerative pain (CDP). Then, some opioids are able to influence several immune parameters. Aim of our study was to assess HMP in patients with CDP in terms of safety and efficacy, to evaluate effects of HMP, within 2 months of observation, on cutaneous cell-mediated immunity (CCMI) as well as other basic immune parameters, and the production of interleukin-2 (IL-2) and interleukin-6 (IL-6). Results have shown that HMP does not influence CCMI nor the sieric levels of immunoglobulins or other immune parameters. Furthermore, it also has no effects on the 3rd and 4th complement fractions, on white blood cells count and T-lymphocyte subpopulations, on presence of seric autoantibodies, nor on production of IL-2 and IL-6. Therapy with HMP has not effects on the studied parameters of the immune system and does not seem to have any influence on the immune competence and immune response in patients with chronic pain.

Hemodynamic variations during thoracic and abdominal stop-flow regional chemotherapy.

AIMS: The aim of this study was to study hemodynamic modifications during thoracic and abdominal stop-flow regional chemotherapy and to evaluate the need for routine hemodynamic monitoring during such kind of procedures. METHODS: Thirty patients, aged 17-67 years, ASA physical status II-III, scheduled for thoracic (group A, n = 15), and abdominal (group B, n = 15) stop-flow regional chemotherapy were enrolled. Heart rate (HR), electrocardiogram lead I and V(5), end tidal carbon dioxide (ETCO(2)), arterial oxygen saturation (SaO(2)), systolic, diastolic and mean arterial pressure (SBP, DBP, MAP), mean pulmonary arterial pressure (MPAP), pulmonary capillary wedge pressure (PCWP), central venous pressure (CVP), cardiac output (CO), stroke volume (SV), stroke index (SI), systemic vascular resistance (SVR), pulmonary vascular resistance (PVR), left cardiac work (LCW), right cardiac work (RCW), left cardiac work index (LCWI), right cardiac work index (RCWI), cardiac index (CI), and body O(2) consumption (VO(2)) were recorded. RESULTS: After aortic and inferior vena cava endovascular occlusion (T(1)), a significant reduction of CO and SV, associated with an increase of CVP, MAP, PAPM and PCWP were observed. A concomitant reduction of CI and increase of SVR and PVR were registered. The VO(2) was significantly reduced compared to basal values in both groups. After deflating aortic and vena cava balloons (T(2)), CO, SV and CI increased with respect to basal value p < 0.05) whereas MAP, CVP, PAPM, PCWP and calculated parameters (SVR, PVR) showed a significant reduction compared to T(1). The oxygen consumption was significantly higher than that of basal values p < 0.05. After hemofiltration (T(3)), all hemodynamic variables were comparable with the basal values. Modifications of direct and calculated parameters, during the stop-flow period, showed a similar trend in both study groups, without any statistically significant difference. No ST modifications at ECG were noted during all perioperative period. CONCLUSIONS: The results of this study have confirmed in both groups, the safety of stop-flow regional chemotherapy procedure, despite endovascular occlusion of the aorta and inferior cava vein. The hemodynamic and oxygenation changes are reversible and did not produce any ST modifications at ECG during all perioperative period. Routine pulmonary artery catheterization is thus unnecessary, except in high cardiac risk patients.

The effects of perioperative ketorolac infusion on postoperative pain and endocrine-metabolic response.

We designed a randomized, double-blind study to assess the analgesic efficacy and safety of perioperative ketorolac infusion in 95 patients undergoing cholecystectomy. The ketorolac group (n = 48) received premedication, combined with ketorolac 30 mg intramuscularly (IM), followed by a ketorolac continuous infusion (2 mg/h). The control group (n = 47) received an IM bolus of NaCl 0.9% (1 mL) followed by continuous saline infusion (2 mL/h) for 24 h. Operative blood losses, postoperative pain, sedation, and on-demand morphine consumption (patient-controlled analgesia [PCA]) were measured. The effects on plasma catecholamines, cortisol, potassium, creatinine, skin bleeding time, prothrombin time (PT), and partial thromboplastin time (PTT) were also evaluated. Ketorolac improved pain scores (P < 0.05) and reduced plasma cortisol concentrations between 2 and 6 h (P < 0.05). No significant differences were observed concerning operative blood losses, glucose concentration, and renal and hemostatic functions. The ketorolac group required less morphine (not significant [NS]) than the control group and had less adverse effects (P = 0.002). Thus, perioperative ketorolac infusion improved the quality of postoperative pain relief, and had no major influence on endocrine-metabolic response and no negative influences on hemostatic and renal functions. This study suggests that preventive ketorolac administration, followed by a continuous infusion, is an easy, useful, and safe method for pain control after abdominal surgery.

[Chronic exposure to inhalation anesthetics and immunity]. / Esposizione cronica agli anestetici inalatori ed immunità.

The existence of a professional disease caused by exposure to general anesthetics has been reported by a number of studies, but opinions still differ as to the effective implications of this type of exposure. The aim of the present study was to analyse alterations in cellular and humoral immunity in anesthetists regularly exposed to general anesthetics. Regression analysis showed that IgA and NK lymphocytes were significantly increased whereas total T lymphocytes reduced in parallel with age and length of service. It can therefore be supposed that the increase in IgA might suggest chronic liver disease, while alterations in the lymphocyte populations, even if closely associated to chronic exposure leading to the hypothesis of a cause-and-effect relationship, do not alter immune system functions since they are similar to those that occur with ageing.

Morphologic and functional features of cyclic alternating pattern (CAP) sequences in normal NREM sleep.

The Cyclic Alternating Pattern (CAP) is an EEG biphasic periodic activity of normal NREM sleep, generally organized in sequences of two or more cycles and correlated to long-lasting fluctuations in the level of arousal. The remaining NREM sleep is characterized by prolonged stationary activities or non-CAP (NCAP). Criteria for the detection of morphology and reactivity of CAP and NCAP segments are defined in the sleep recordings of 10 healthy young adults. Standard sleep variables and CAP rates, referred to the ratio of CAP time to Total NREM sleep time (CAPR/NREM) and to each NREM sleep stage, were scored for statistical inferences and correlations. CAPR/NREM may be considered an additional non-redundant sleep variable which determines the measure of arousal instability during NREM sleep. The relationship between CAP and the biphasic behavior of microarousals is discussed.
