Refractory pain during care procedures causes a real challenge for terminally ill patients. We are hereby publishing three cases of patients who received repeated procedural sedations using propofol during the painful care procedures. All patients experience pain relief with no side effects although care procedures initially were a traumatic experience to them despite the usual medication. This therapeutic solution, which would need to be assessed on a case-by-case basis by evaluating the benefit-risk balance, could become a suitable comfort treatment used by palliative care teams., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2021.

Essentials Bleeding incidence as hemorrhagic risk factors are unknown in palliative care inpatients. We conducted a multicenter observational study (22 Palliative Care Units, 1199 patients). At three months, the cumulative incidence of clinically relevant bleeding was 9.8%. Cancer, recent bleeding, thromboprophylaxis and antiplatelet therapy were independent risk factors., Summary: Background The value of primary thromboprophylaxis in patients admitted to palliative care units is debatable. Moreover, the risk of bleeding in these patients is unknown. Objectives Our primary aim was to assess the bleeding risk of patients in a real-world practice setting of hospital palliative care. Our secondary aim was to determine the incidence of symptomatic deep vein thrombosis and to identify risk factors for bleeding. Patients/Methods In this prospective, observational study in 22 French palliative care units, 1199 patients (median age, 71 years; male, 45.5%), admitted for the first time to a palliative care unit for advanced cancer or pulmonary, cardiac or neurologic disease were included. The primary outcome was adjudicated clinically relevant bleeding (i.e. a composite of major and clinically relevant non-major bleeding) at 3 months. The secondary outcome was symptomatic deep vein thrombosis. Results The most common reason for palliative care was cancer (90.7%). By 3 months, 1087 patients (91.3%) had died and 116 patients had presented at least one episode of clinically relevant bleeding (fatal in 23 patients). Taking into account the competing risk of death, the cumulative incidence of clinically relevant bleeding was 9.8% (95% confidence interval [CI], 8.3-11.6). Deep vein thrombosis occurred in six patients (cumulative incidence, 0.5%; 95% CI, 0.2-1.1). Cancer, recent bleeding, antithrombotic prophylaxis and antiplatelet therapy were independently associated with clinically relevant bleeding at 3 months. Conclusions Decisions regarding the use of thromboprophylaxis in palliative care patients should take into account the high risk of bleeding in these patients., (© 2016 International Society on Thrombosis and Haemostasis.)

Background: At the end of life, patients may feel refractory pain during care procedures although they receive appropriate analgesia. They can benefit from a short-term sedation. Propofol is used for procedural sedation in emergency or reanimation departments. It may be adapted in a palliative care unit., Objective: The main objective was to verify whether propofol could allow us to administer care without causing major pain to patients with refractory pain at the end of life., Design: We conducted an open, prospective, and uncontrolled pilot study., Setting/subjects: The study was conducted in one palliative care center in France. The subjects were patients with an estimated prognosis less than three months who experienced pain during care procedures, although they receive appropriate analgesia., Results: Ten patients were included. Care was delivered with no major pain for 9 patients out of 10. The average duration of induction to reach deep sedation was 4 minutes (2-8) and of care procedures was 13 minutes (7-32). On average, the patient woke up 11.5 minutes after we stopped injecting propofol (7-18). Only one patient experienced a significant adverse effect caused by propofol, but it did not have any harmful consequence except the interruption of care procedures., Conclusion: Transitory sedation using propofol for terminally ill patients hospitalized in a palliative care unit can offer optimal comfort during painful care procedures without significant complications. Patients woke up quickly. Further studies will have to be conducted to verify these initial results and make sure there are no major drawbacks.

Background: Methadone has been reported to be as effective as morphine for cancer pain management. It is commonly used as an alternative opioid in case of insufficient relief., Objective: Our aim was to assess efficacy and tolerance of opioid rotation to methadone for refractory cancer pain management in palliative care unit (PCU) inpatients., Methods: All the patients undergoing opioid rotation to methadone from 2008 to 2011 in two PCUs (Lyon and Nice, France) were included. Pain assessments were undertaken on day 0 (D0), day 3 (D3), day 7 (D7), and day 14 (D14) using a visual analogue scale (VAS; 0-10) and the Douleur Neuropathique 4 (DN4) scale for neuropathic pain. Patients reported pain relief using a 4-point Likert scale (1=no relief; 4=important relief )., Results: Nineteen patients (7 females) with a median age of 55 (Q1-Q3; 44-58) underwent methadone rotation. The most common type of cancer was gastrointestinal. Seventeen patients had a diagnosis of mixed pain syndromes. Morphine equivalent daily dose (MEDD) prior to switching was 480 mg (Q1-Q3; 100-1021), and at least two nonmethadone opioid rotations had already been done for 13 patients. Between D0 and D7, the VAS score decreased by 4 points (p<0.001). The DN4 score became negative on D7 for 11 of 17 patients (65%). On D7, 16 of 18 patients (89%) expressed moderate to greater than moderate pain relief. Methadone was discontinued in one patient on D7 because it was deemed ineffective and for 8 patients, who were unable to take oral drugs, it was discontinued after D14., Conclusion: Our results suggest that methadone is effective and well tolerated for refractory cancer pain.

Objectives: This study was undertaken to evaluate the impact of paramedical hospice specialists on hospitalization of terminally-ill patients in acute medical emergencies., Method: In this intervention, the SAMU (French medical emergency call center) responded to requests for emergency aid at the homes of terminally-ill patients by sending to the patient's home, together with a physician and the emergency ambulance team, a team composed of a nurse and a volunteer, both trained in hospice (terminal) care . When the patient wished to stay at home, the hospice team remained to support the patient and family and to provide comfort care until the crisis situation stabilized. This before-and-after study compares SAMU calls during the first year of the intervention to those in the preceding year., Results: During the intervention period, 14% of patients were hospitalized compared with 48% during the reference year (p<0.0001), for a relative risk of hospitalization of 0.29. The emergency hospice team was considered to be not only complementary but also essential in emergency medical situations for patients receiving palliative care at home. Interaction with existing services did not present problems. Families benefited from considerable assistance in particularly difficult situations., Conclusion: A team of paramedical hospice specialists, acting on request of the SAMU, provides a concrete and useful response to problems of unwanted hospitalization in acute emergencies for home-based terminally ill patients. This type of organization is consistent with respect for the patient's choice to remain at home until the end of life. Prevention of unwanted hospitalization and heroic measures should undoubtedly result in cost savings more than sufficient to fund this program.

Amyotrophic lateral sclerosis (ALS) is an illness in which respiratory complications often determine the terminal prognosis. Emergency situations lead one to pose questions concerning an endotracheal intubation or a tracheotomy. A tracheotomy should not be performed during an emergency situation. A tracheotomy necessitates a stable condition and prior reflection. Orotrachael intubation is the method of choice during emergency situations requiring invasive ventilation or airway protection. Intubation during an emergency situation presents specific problems: the lack of knowledge concerning the person and their pre-established desires, the impossibility of evaluating the potential reversibility of an acute pathology, the risk of not being able to wean the patient off the ventilator and the lack of time to gather all the elements necessary for a well-thought out decision. It may be appropriate for emergency personnel to introduce mechanical ventilation and leave the reflection for a later moment, but this approach is not suitable for people in end of life situations in which the person and the family wish to avoid all unreasonable therapeutics. One solution may be to develop among emergency care teams the practice of using non-invasive ventilation and airway clearance techniques as well as developing palliative care knowledge. Orotracheal intubation in an emergency situation presents certain practical difficulties, notably regarding the choice of anesthetics. Preventings situations where emergency intubation may be necessary is probably best obtained by anticipating acute problems, by preparing the ill person, the family and the care givers, by coordinating the potential care providers and by educating emergency personnel in palliative care.

Objectives: Rapid sequence intubation (RSI) with the association of etomidate and succinylcholine is the French "Gold standard" for urgent "full stomach" endotracheal intubations. The aim of this study is to assess the fentanyl as a co-induction agent to take over the sedation between the RSI and the keeping of sedation, which is a critical period in which harmful neuro-vegetatives events, and awakening signs are frequently seen., Study Design: Randomized, double blind controlled prospective study, after acceptation by the local ethical committee., Patients and Methods: Three groups of patients undergoing RSI in the intensive care unit and by the out-of-hospital medical team were compared: group A patients received fentanyl 3 micrograms kg-1 during RSI, before paralysis was induced. Group B patients received the same dose of fentanyl immediately after endotracheal intubation. Group C patients did not received fentanyl (control group). Outcome measures were awakening signs arrival (respiratory movements, eyes opening, spontaneous limb movements), Ramsay score assessment, and haemody namics. Attempt at intubation and vomiting incident were also measured. Discrete data were compared by chi-2 analysis, continuous data were compared with two-way analysis of variance. A p value < 0.05 was the significant threshold., Results: Thirty-six patients were enrolled and completed the study. All the included patients presented awakening signs. The use of fentanyl did not prevent the recourse of other sedative medications. Ten minutes after endotracheal intubation, significant differences has been noticed for the awakening signs arrival between fentanyl groups (A: 42% and B: 36%) and control group (C: 77%). The Ramsay score evolution follows the same variation. All the patients were intubated on the first attempt, there was no vomiting incident noticed., Conclusion: The use of fentanyl, as a co-induction agent with etomidate and succinylcholine during RSI, allows a significant delay of the awakening signs arrival and attenuate the neurovegetative response during the minutes after endotracheal intubation after RSI, without deleterious haemodynamic effects.

Introduction: The Samu-Centres 15 (French medical emergency centers) are regularly solicited for patients undergoing palliative treatment at their homes and presenting acute complications. No specific response is foreseen for such situations. However, the problems are frequent and crucial. Who is the most appropriate person to intervene? Should the patient be hospitalised or not? Does the patient require reanimation? What are the patients' and families' needs in such circumstances? In an attempt to outline the answers, we collected the opinion of the families concerned., Method: We interviewed all the families soliciting the Samu for emergencies concerning patients undergoing palliative treatment at home. To collect their feelings and experience, we used a survey in the form of non directive interviews., Results: In a month, 12 telephone calls concerning our matter were received by the Centre 15 of the Alpes-Maritimes. The interview with the families revealed many elements such as loneliness, guilty feelings, responsibility, surprise when the death occurs, the poor adaptation of the structures and the lack of training of the emergency medical staff., Conclusion: The issues underlined require enhanced attention: how can we help the families in such situations? How should the emergency medical staff be trained in accompanying death and palliative treatment? Are the existing structures adapted?

Objective: To evaluate the sensitivity, specificity, and predictive values of an elevated anion gap as an indicator of hyperlactatemia and to assess the contribution of blood lactate to the serum anion gap in critically ill patients., Design: Prospective study., Setting: General intensive care unit of a university hospital., Patients: 498 patients, none with ketonuria, severe renal failure or aspirin, glycol, or methanol intoxication., Measurements and Results: The anion gap was calculated as [Na+]-[Cl-]-[TCO2]. Hyperlactatemia was defined as a blood lactate concentration above 2.5 mmol/l. The mean blood lactate concentration was 3.7 +/- 3.2 mmol/l and the mean serum anion gap was 14.3 +/- 4.2 mEq/l. The sensitivity of an elevated anion gap to reveal hyperlactatemia was only 44% [95% confidence interval (CI) 38 to 50], whereas specificity was 91% (CI 87 to 94 and the positive predictive value was 86% (CI 79 to 90). As expected, the poor sensitivity of the anion gap increased with the lactate threshold value, whereas the specificity decreased [for a blood lactate cut-off of 5 mmol/l: sensitivity = 67% (CI 58 to 75) and specificity = 83% (CI 79 to 87)]. The correlation between the serum anion gap and blood lactate was broad (r2 = 0.41, p < 0.001) and the slope of this relationship (0.48 +/- 0.026) was less than 1 (p < 0.001). The serum chloride concentration in patients with a normal anion gap (99.1 +/- 6.9 mmol/l) was comparable to that in patients with an elevated anion gap (98.8 +/- 7.1 mmol/l)., Conclusions: An elevated anion gap is not a sensitive indicator of moderate hyperlactatemia, but it is quite specific, provided the other main causes of the elevated anion gap have been eliminated. Changes in blood lactate only account for about half of the changes in anion gap, and serum chloride does not seem to be an important factor in the determination of the serum anion gap.

Intracranial pressure depends on cerebral tissue volume, cerebrospinal fluid volume (CSFV) and cerebral blood volume (CBV). Physiologically, their sum is constant (Monro-Kelly equation) and ICP remains stable. When the blood brain barrier (BBB) is intact, the volume of cerebral tissue depends on the osmotic pressure gradient. When it is injured, water movements across the BBB depend on the hydrostatic pressure gradient. CBV depends essentially on cerebral blood flow (CBF), which is strongly regulated by cerebral vascular resistances. In experimental studies, a decrease in oncotic pressure does not increase cerebral oedema and intracranial hypertension (ICHT). On the other hand, plasma hypoosmolarity increases cerebral water content and therefore ICP, if the BBB is intact. If it is injured, neither hypoosmolarity nor hypooncotic pressure modify cerebral oedema. Therefore, all hypotonic solutes may aggravate cerebral oedema and are contra-indicated in case of ICHT. On the other hand, hypooncotic solutes do not modify ICP. The osmotic therapy is one of the most important therapeutic tools for acute ICHT. Mannitol remains the treatment of choice. It acts very quickly. An i.v. perfusion of 0.25 g.kg-1 is administered over 20 minutes when ICP increases. Hypertonic saline solutes act in the same way, however they are not more efficient than mannitol. CO2 is the strongest modulating factor of CBF. Hypocapnia, by inducing cerebral vasoconstriction, decreases CBF and CBV. Hyperventilation is an efficient and rapid means for decreasing ICP. However, it cannot be used systematically without an adapted monitoring, as hypocapnia may aggravate cerebral ischaemia. Hyperthermia is an aggravating factor for ICHT, whereas moderate hypothermia seems to be beneficial both for ICP and cerebral metabolism. Hyperglycaemia has no direct effect on cerebral volume, but it may aggravate ICHT by inducing cerebral lactic acidosis and cytotoxic oedemia. Therefore, infusion of glucose solutes is contra-indicated in the first 24 hours following head trauma and blood glucose concentration must be closely monitored and controlled during ICHT episodes.

Liver injury is a well-known complication of exertional heat stroke. However severe acute irreversible liver dysfunction is rarely associated. Persistent centrolobular hepatocellular necrosis without any regeneration remains very uncommon. We report a case of fatal acute liver failure occurring after exertional heat stroke. Despite the conventional symptomatic treatment, especially active cooling, the patient experienced multiple organ failure with brain death 6 days after his admission. In this case, a chronic treatment with neuroleptic and anticholinergic agents may be considered as a predisposing factor.
