Oxycodone, Morphine, and Fentanyl in Patients With Chronic Pain: Proposal of Dose-Specific Concentration Ranges.

BACKGROUND: Interpreting opioid concentrations is challenging because of the lack of reference ranges. Therefore, the authors aimed to propose dose-specific concentration ranges in serum for oxycodone, morphine, and fentanyl in patients with chronic pain, based on concentration measurements from a large number of patients and supported by theoretical pharmacokinetic calculations and previously published concentrations. METHODS: The opioid concentrations in patients undergoing therapeutic drug monitoring (TDM) for various indications (TDM group) and patients with cancer (cancer group) were investigated. Patients were divided based on the daily opioid doses, and the 10th and 90th percentiles of the concentrations in each dose interval were evaluated. In addition, the expected average serum concentrations were calculated for each dose interval based on published pharmacokinetic data, and a targeted literature search for previously reported dose-specific concentrations was performed. RESULTS: The opioid concentrations in 1054 patient samples were included: 1004 in the TDM group and 50 in the cancer group. In total, 607 oxycodone, 246 morphine, and 248 fentanyl samples were evaluated. The authors proposed dose-specific concentration ranges based mainly on 10th-90th percentiles of the concentrations measured in patient samples, whereas the calculated average concentrations and previously published concentrations were used to adjust the ranges. In general, results from calculations and concentrations retrieved from previous literature were within the 10th-90th percentiles of concentrations from patient samples. However, the lowest calculated average concentrations of fentanyl and morphine were below the 10th percentiles of patient samples in all dose groups. CONCLUSIONS: The proposed dose-specific ranges may be useful for interpreting steady-state opioid serum concentrations in clinical and forensic settings.

Prospective evaluation of an enhanced recovery after surgery (ERAS) pathway in a Norwegian cohort of patients with suspected or advanced ovarian cancer.

OBJECTIVE: This prospective cohort study evaluated the introduction of an enhanced recovery after surgery (ERAS) pathway in a tertiary gynecologic oncology referral center. Compliance and clinical outcomes were studied in two separate surgical cohorts. METHODS: Patients undergoing laparotomy for suspected or verified advanced ovarian cancer at Oslo University Hospital were prospectively included in a pre- and post-implementation cohort. A priori, patients were stratified into: cohort 1, patients planned for surgery of advanced disease; and cohort 2, patients undergoing surgery for suspicious pelvic tumor. Baseline characteristics, adherence to the pathway, and clinical outcomes were assessed. RESULTS: Of the 439 included patients, 235 (54%) underwent surgery for advanced ovarian cancer in cohort 1 and 204 (46%) in cohort 2. In cohort 1, 53% of the patients underwent surgery with an intermediate/high Aletti complexity score. Post-ERAS, median fasting times for solids (13.1 hours post-ERAS vs 16.0 hours pre-ERAS, p<0.001) and fluids (3.7 hours post-ERAS vs 11.0 hours pre-ERAS, p<0.001) were significantly reduced. Peri-operative fluid management varied less and was reduced from median 15.8 mL/kg/hour (IQR 10.8-22.5) to 11.5 mL/kg/hour (IQR 9.0-15.4) (p<0.001). In cohort 2 only there was a statistically significant reduction in length of stay (mean (SD) 4.3±1.5 post-ERAS vs 4.6±1.2 pre-ERAS, p=0.026). Despite stable readmission rates, there were significantly more serious complications reported in cohort 1 post-ERAS. CONCLUSIONS: ERAS increased adherence to current standards in peri-operative management with significant reduction in fasting times for both solids and fluids, and peri-operative fluid administration. Length of stay was reduced in patients with suspicious pelvic tumor. Despite serious complications being common in patients with advanced disease undergoing debulking surgery, a causal relationship with the ERAS protocol could not be established. Implementing ERAS and continuous performance auditing are crucial to advancing peri-operative care of patients with ovarian cancer.

Patient-reported nausea after implementation of an enhanced recovery after surgery protocol for gynae-oncology patients.

OBJECTIVES: This study aimed to analyze the adherence to strategies to prevent post-operative nausea and vomiting after implementation of an enhanced recovery after surgery (ERAS) protocol for gynae-oncology patients. Patient-reported nausea before and after ERAS was also studied. METHODS: This prospective observational study included all patients undergoing laparotomy for a suspicious pelvic mass or confirmed advanced ovarian cancer before (pre-ERAS) and after the implementation of ERAS (post-ERAS) at Oslo University Hospital, Norway. Patients were a priori stratified according to the planned extent of surgery into two cohorts (Cohort 1: Surgery of advanced disease; Cohort 2: Surgery for a suspicious pelvic tumor). Clinical data including baseline characteristics and outcome data were prospectively collected. RESULTS: A total of 439 patients were included, 243 pre-ERAS and 196 post-ERAS. At baseline, 27% of the patients reported any grade of nausea. In the post-ERAS cohort, statistically significantly more patients received double post-operative nausea and vomiting prophylaxis (64% pre-ERAS vs 84% post-ERAS, p<0.0001). There was no difference in the need for rescue medication (82% pre-ERAS vs 79% post-ERAS; p=0.17) and no statistically significant difference between pre- and post-ERAS or between the surgical cohorts in patient-reported nausea of any grade on day 2. Patients who reported none/mild nausea on day 2 had significantly less peri-operative fluid administered during surgery than those who reported moderate or severe nausea (median 12.5 mL/kg/hour vs 16.5 mL/kg/hour, p=0.045) but, in multivariable analysis, fluid management did not remain significantly associated with nausea. CONCLUSION: Implementation of an ERAS protocol increased the adherence to post-operative nausea and vomiting prevention guidelines. Nausea, both before and after laparotomy, remains an unmet clinical need of gynae-oncology patients also in an ERAS program. Patient-reported outcome measures warrant further investigation in the evaluation of ERAS.

Interhospital transport of critically ill patients: A prospective observational study of patient and transport characteristics.

BACKGROUND: The cohort of critically ill patients transported between Intensive Care Units (ICUs) in Norway has not been studied previously. The aim of this study was to describe the characteristics of patients and transports for different types of interhospital transfers and explore whether there were differences in morbidity and mortality between the different transfer categories and the general Norwegian ICU population. METHODS: All transports of critically ill adult patients transferred between two geographically different Intensive Care Units during a one-year period were registered. Patient and transport data were obtained from The Norwegian Intensive Care Registry, The Norwegian Cause of Death Registry, the hospital Electronic Patient Journal, the Air Ambulance Journal System, and the Emergency Medical Communication Centre database. RESULTS: 821 transports of 788 surgical and medical patients were enrolled. Simplified Acute Physiology Scores (SAPSII) were 43, 36 and 38 for urgent secondary transport, non-urgent secondary transport and return transfers, respectively. These were comparable to nationwide SAPSII scores that were 40 for university hospitals and 34 for local hospitals during the same time period. The return transfers had a median SOFA-score of 4.7 and 53% were mechanically ventilated. Only 33% of return transfers were performed by established teams. CONCLUSION: Intensive care patients transferred between ICUs are as critically ill as the rest of the ICU population, with a similar morbidity and mortality. The return transfers of ICU-patients appear under-triaged compared to secondary transports in terms of allocated resources.

Prevalence, Location, and Characteristics of Chronic Pain in Intensive Care Survivors.

BACKGROUND: A growing number of studies have addressed the long-term consequences of intensive care unit (ICU) treatment, but few have studied the prevalence of chronic pain and pain characteristics longitudinally. AIMS: The goal of the work described here was to investigate the prevalence and characteristics of chronic pain in ICU survivors 3 months and 1 year after ICU discharge and to identify risk factors for chronic pain 1 year after ICU discharge. DESIGN: The design used was an explorative and longitudinal study. SETTING/PATIENTS: The patients in this work had stayed >48 hours in two mixed ICUs in Oslo University Hospital, a tertiary referral hospital. METHODS: Patients completed a survey questionnaire 3 months and 1 year after ICU discharge. Pain was assessed using the Brief Pain Inventory-Short Form. RESULTS: At 3 months after discharge, 58 of 118 ICU survivors (49.2%) reported pain, and at 1 year after discharge, 34 of 89 survivors (38.2%) reported pain. The most common sites of pain at 3 months were the shoulder and abdomen; the shoulder remained the second most common site at 1 year. There was an increase in the interference of pain with daily life at 1 year. Possible risk factors for chronic pain at 1 year were increased severity of illness, organ failure, ventilator time >12 days, and ICU length of stay >15 days. The most common sites of pain were not linked to the admission diagnosis. CONCLUSIONS: These findings may enable health care providers to improve care and rehabilitation for this patient group.

Intensive care survivor-reported symptoms: a longitudinal study of survivors' symptoms.

BACKGROUND: There is growing interest in potential long-term outcomes following intensive care, but few researchers have studied the prevalence of multiple symptoms or the association between pain and other symptoms. AIMS: To investigate the prevalence of anxiety, depression, fatigue, sleep disturbance and post-traumatic stress symptoms (PTSS) among intensive care survivors 3 months and 1 year after being discharged from an intensive care unit (ICU) and to determine whether pain is associated with higher prevalence of these symptoms 3 months and 1 year after ICU stay. STUDY DESIGN: Exploratory, longitudinal cohort of intensive care survivors from two mixed ICUs in a tertiary referral hospital in Norway. METHODS: Intensive care survivors completed surveys at 3 months (n = 118) and 1 year (n = 89) after ICU discharge. Clinical Trials: NCT02279212. RESULTS: Prevalence rates of intensive care survivors' symptoms were pain 58 (49·2%), anxiety/depression 24/118 (20·8%), fatigue 18/118(15·3%), PTSS 15 (12·8%) and sleep disturbance 58/118 (49·2%) at 3 months after ICU discharge (n = 118). Prevalence rates at 1 year (n = 89) changed only slightly to pain 34 (38·2%), anxiety/depression 17 (20·0%), fatigue 12 (13·8%), PTSS 13 (15·1%) and sleep disturbance 40/89 (46·5%). Associations were strong between pain and presence of sleep disturbance, anxiety/depression, PTSS and fatigue. CONCLUSIONS: Intensive care survivors have multiple symptoms and the prevalence rates of these symptoms remained almost unchanged from 3 months to 1 year after ICU discharge. The presence of pain was associated with high odds for the presence of sleep disturbance, anxiety/depression, PTSS and fatigue, compared to a no-pain group. ICU survivors may benefit from targeted interventions designed to alleviate the symptom burden. RELEVANCE TO CLINICAL PRACTICE: Knowledge about ICU survivor's prevalence and risk for having multiple symptoms may help health care professionals to give better care, if needed, to the ICU survivors.

Complaints to the Norwegian System of Patient Injury Compensation 2001-14 following nerve blockade. / Klager etter nerveblokade til Norsk pasientskadeerstatning 2001 ­ 14.

BACKGROUND: There has been a steady increase in cases reported to the Norwegian System of Patient Injury Compensation (NPE). We wished to look into what might characterise those cases of central and peripheral nerve blockade for anaesthesia that led to compensation claims. MATERIAL AND METHOD: Cases with codes for central and peripheral blockade within the field of anaesthesiology were retrieved from the NPE database for the period 2001 ­ 14. The cases were evaluated on the basis of variables including sex, age, type of anaesthesia, diagnosis, type of injury, site of injury, damages received, and written descriptions of treatment and injury. The expert reports were anonymised and reviewed in detail. RESULTS: A total of 339 patient compensation claims relating to nerve blockade were identified, of which 149 concerned spinal anaesthesia, 142 epidural anaesthesia, 21 combined spinal and epidural anaesthesia and 27 peripheral nerve blockade. The group consisted of 236 women and 103 men, and the average age was 46 years. The 339 cases comprised 0.8 % of all cases reported to the NPE in this period. A total of 107 claims resulted in compensation. Eighty-two million Norwegian kroner were paid out in total. INTERPRETATION: Peripheral and central nerve blockade accounts for only a small proportion of cases handled by the NPE. Only one in three applicants had their claim upheld, but when claims were upheld, the injuries were often severe and led to substantial pay-outs.

The effect of tracheotomy on drug consumption in patients with acute aneurysmal subarachnoid hemorrhage: an observational study.

BACKGROUND: Patients with aneurysmal subarachnoid hemorrhage (aSAH) are common in intensive care units (ICU). In patients with aSAH, sedation is used as a neuroprotective measure in order to secure adequate cerebral perfusion pressure (CPP). Compared with the use of an endotracheal tube, a tracheotomy has the advantage of securing the airway at a much lower level of distress, and aSAH patients can often be awakened more rapidly. Little is known about the impact of tracheotomy on the consumption of sedative/analgesic and vasoactive drugs and the maintenance of CPP within defined limits in aSAH patients. METHODS: We conducted an observational study of aSAH patients who underwent percutaneous tracheotomy. A prospective registry of patient data was supplemented with retrospective retrievals from medical records. Sedative, analgesic and vasoactive drug doses were registered for 3 days prior to and after percutaneous tracheotomy, respectively. Blood pressure, CPP, and the mode of mechanical ventilation were registered 24 h prior to and after tracheotomy. RESULTS: Between January 2001 and June 2009, 902 aSAH patients were admitted to our hospital; 74 (8%) were deeply comatose/dying upon arrival. The ruptured aneurysm was repaired in 828 patients (surgical repair 50%) and percutaneous tracheotomy was performed 182 times in 178 patients (59 men and 119 women). This subpopulation (178 of 828 patients) was significantly older (56 vs. 53 years) and presented with a more severe Hunt & Hess grade (p < 0.001). Percutaneous tracheotomy caused a marked decline in mean daily consumption of the analgesics/sedatives fentanyl, midazolam, and propofol, as well as the vasoactive drugs noradrenaline and dopamine. These declines were statistically and clinically significant. The mean CPP was 76 mmHg (SD 8.6) the day before and 79 mmHg (SD 9.6) 24 h after percutaneous tracheotomy. After percutaneous tracheotomy, mechanical ventilatory support could be reduced to a patient-controlled ventilatory support mode in a significant number of patients (p < 0.001). CONCLUSIONS: Percutaneous tracheotomy in aSAH patients is a swift procedure with low risk that is associated with a significant decline in the consumption of sedative/analgesic and vasoactive drugs while clinical surveillance parameters remain stable or improve.

The use of Instanyl® in the treatment of breakthrough pain in cancer patients: a 3-month observational, prospective, cohort study.

PURPOSE: Instanyl® (intranasal fentanyl spray) is a novel treatment for breakthrough pain (BTP) in cancer patients. It has shown a rapid onset of pain relief in clinical trials. This study examines the use of Instanyl® in real-life settings. METHODS: A 3-month observational, prospective, cohort study of cancer patients with BTP receiving Instanyl® (50, 100, or 200 µg) under routine clinical practice. Data were collected at three time points corresponding with routine clinic visits - baseline, Week 4, and Week 13. PRIMARY OUTCOMES: success of titration and maintenance dose after titration. SECONDARY OUTCOMES: change in maintenance dose of Instanyl® and level of background pain medication; Brief Pain Inventory--Short Form (BPI-SF) and Patient Treatment Satisfaction Scale (PTSS) scores; adverse drug reactions (ADRs). RESULTS: Titration with Instanyl® was successful in 84.5 % of 309 patients; most patients were titrated at the lowest dose (50 µg). The majority showed no change in maintenance dose, with little change in the level of background pain medication. BPI-SF and PTSS scores significantly improved from baseline to Week 4. The main reason for terminating Instanyl® was death, as expected due to the underlying disease; incidence of ADRs was low and no fatal ADRs were reported. CONCLUSIONS: In a real-life group of cancer patients with disease progression, Instanyl® was titrated successfully at doses <200 µg in the majority of patients, requiring only one dose, with no further change in maintenance dose. Pain severity, impact of pain on daily life, and treatment satisfaction significantly improved with Instanyl® treatment. No unexpected ADRs occurred.

Skin conductance algesimeter is unreliable during sudden perioperative temperature increases.

OBJECTIVES: Pain assessment in anesthetized and non-communicative patients remains a challenge. Clinical signs such as tachycardia, hypertension, sweat and tears, have a low specificity for pain and should therefore ideally be replaced by more specific monitoring techniques. Skin conductance variability has been demonstrated to establish a patients' sensitivity to pain, but may be influenced by temperature changes that leads to profuse sweating. The aim of this pilot study was to test skin conductance changes during sudden temperature changes due to hyperthermic intraperitoneal chemotherapy (HIPEC) perfusation. METHODS: We investigated skin conductance algesimeter (SCA) in ten consecutive patients undergoing cytoreductive surgery and HIPEC. Results from the SCA was compared to other standard physiological variables at seven time points during the surgical procedure, in particular during the period with hyperthermic intraabdominal perfusion leading to an increase in the patients core temperature. RESULTS: Nine out of ten patients had an increase in the SCA measurements during the HIPEC phase correlating the increase in temperature. CONCLUSION: SCA is unreliable to detect increased pain sensation during sudden perioperative temperature changes in adult patients.

Mycophenolate pharmacokinetics and inosine monophosphate dehydrogenase activity in liver transplant recipients with an emphasis on therapeutic drug monitoring.

BACKGROUND: The pharmacokinetics of the immunosuppressant mycophenolic acid (MPA) demonstrates high inter- and intra-patient variability. Variation in the binding of MPA to albumin has been postulated to be an important factor in this variability, and monitoring of free MPA has been suggested to improve therapeutic drug monitoring (TDM) of MPA. Inosine monophosphate dehydrogenase (IMPDH) is the target enzyme for MPA, therefore the IMPDH activity in lymphocytes can serve as a marker of the MPA-specific response. This study aimed to explore how the albumin concentration influences the free concentration of MPA in liver transplant recipients and to assess whether alteration in the free MPA influences IMPDH activity in CD4 + cells. METHODS: Blood samples were taken from 20 liver transplant recipients on two separate occasions (days 3-5 and 16-21). Total and free concentrations of MPA, and IMPDH activity were measured during the first 4 h of each dose interval. RESULTS: Albumin levels correlated with the free fraction of MPA. However, the total MPA and free MPA were equal predictors of the immunosuppressive response as defined by IMPDH activity. CONCLUSION: Total and free MPA are equally good predictors of the immunosuppressive effect exerted by MPA as defined by IMPDH activity. IMPDH activity measurements represent a promising approach to TDM in patients treated with MPA.

Potentially Severe Incidents During Interhospital Transport of Critically Ill Patients, Frequently Occurring But Rarely Reported: A Prospective Study.

OBJECTIVES: The out-of-hospital environment can pose significant challenges to the quality and safety of interhospital transport of critically ill patients. Because we lack knowledge of the occurrence of incidents, their potential consequences, and whether they are actually reported, this study was initiated. METHODS: Two different services in Norway were asked to self-report incidents after every interhospital transport of critically ill patients. Sampling lasted for 12 and 8 months, respectively. An expert group evaluated each incident for severity and demand for reporting into the hospital's electronic incident reporting system. One year later, the hospital's reporting system was scrutinized to determine the number of incidents actually reported. RESULTS: A total of 455 transports of critically ill patients were performed, resulting in 294 unique incidents reported: medical (15%), technical (25%), missing equipment (17%), and personal failures and communication difficulties (42%). Only 3 (1%) of the 294 unique incidents were actually reported in the hospital's electronic incident reporting system. The experts were inconsistent in which incidents should have been reported and to what degree checklists, standard operating procedures, simulation, and training could have prevented the incidents. CONCLUSIONS: This study of interhospital transports of critically ill patients reveals a very high number of incidents. Despite this fact, these incidents are severely underreported in the hospital's electronic incident reporting system. This suggests that learning is lost and errors with predominant probability are repeated. These results emphasize the existing challenges in regard to the quality and safety of interhospital transport of critically ill patients.

Frédéric Chopin and his suffering.

BACKGROUND: In 2010 we celebrated the bicentennial of Chopin's birth. He left more than 230 fantastic compositions, often described as romantic, emotional and poetic. Chopin composed almost exclusively for piano solo and has been called the pianists' composer. From his teens he suffered from respiratory tract infections, gradually accompanied by haemoptysis, pronounced breathing problems, diarrhoea and loss of weight. He experienced part of his adult life as a period of great suffering. He was 39 years old when he died. The assumed cause of death was tuberculosis, but other possible differential diagnoses have been suggested in recent years. MATERIAL AND METHOD: In order to examine the different diagnostic alternatives, a non-systematic search of the literature was carried out in PubMed, Embase, Current Contents, Google and relevant reference books. RESULTS: The official cause of death was tuberculosis, but the autopsy report has never been found. Both cystic fibrosis and alpha-1-antitrypsin deficiency are possible differential diagnoses that can explain his symptoms. INTERPRETATION: In spite of a disabling disease, Chopin was musically creative right to the end of his life. His suffering must have influenced his musical expression, which is characterised by intimacy and sentimentality. It is unlikely that we will ever find the true cause of death.

Experience of unpleasant sensations in the mouth after injection of saline from prefilled syringes.

BACKGROUND: Nurses at The Norwegian Radium Hospital have reported that some patients notice an unpleasant smell or taste in accordance with flushing of intravenous lines with commercially available prefilled syringes. We have conducted a study in healthy volunteers to investigate the occurrence, consistency and intensity of this phenomenon. METHODS: A randomised, blinded, crossover study comparing commercial available prefilled saline 9 mg/ml syringes to saline 9 mg/ml for injection in polyethylene package was performed in 10 healthy volunteers. The volunteers were given intravenous injections of varying volume and speed. Data were analysed using descriptive statistics, and also Wilcoxon Signed Rank Test to compare groups. RESULTS: After intravenous injection, 2 of 15 recordings demonstrated any sensation of smell or taste after injection of saline from polyethylene package, while 14 of 15 recordings noted a sensation after injection of saline from prefilled syringes. The intensity of the unpleasant sensation was rated significantly higher after injection of saline from prefilled syringes compared to saline from polyethylene (p = 0.001). CONCLUSIONS: Injection of saline from prefilled syringes in healthy volunteers resulted in an experience of bad taste or smell. It is important that nurses and health workers are aware of the phenomenon as described in this article in order to choose the preferred product for a given patient.

Dynamic assessment of the pupillary reflex in patients on high-dose opioids.

Background and aims Pupil size and reaction are influenced by opioids, an effect that is not considered to be affected by opioid tolerance. As clinicians have observed patients on high-dose opioids who exhibited seemingly normal pupil sizes, we wanted to dynamically assess the pupillary reflex in cancer patients on high-dose opioids. Methods We performed a dynamic assessment of the pupillary reflex in cancer patients on high-dose opioids and a control group of healthy volunteers using a portable, monocular, infrared pupillometer. We also performed a clinical examination and measured blood concentrations of opioids and their active metabolites. Results Sixty three patients who were on opioids for 2 months (median time) and on an oral morphine equivalent dose of 250 mg (median dose) were investigated. Most patients used more than one opioid. When correcting for age, pupil size in the group that had received no increase of opioid dose over the last 14 days was not significantly different from pupil size in the healthy volunteer group (p = 0.76), while the group that had increased the dose of opioids differed significantly from healthy volunteers (p = 0.006). We found no statistically significant correlation between total oral morphine equivalents and pupillary reactions or between blood opioid or opioid metabolite concentrations and baseline pupillary changes. Conclusion Pupillary changes do take place in patients on opioids. However, tolerance to these changes occurs when medication is not increased over time. Dynamic pupillometry can give additional information about the degree of tolerance to opioids. Implications These findings elucidate previous misconceptions regarding pupillary effects and tolerance to opioids.

Interhospital transport of critically ill patients: experiences and challenges, a qualitative study.

BACKGROUND: No consensus based national standard for interhospital transports of critically ill patients exists in Norway. The local hospitals are responsible for funding, organizing and performing these transports, resulting in potentially different level of care for the critically ill patients depending on local hospital resources and not the level of severity in the patient's condition. The aim of this study was to examine how these transports are executed and to discover challenges during transports and potentials of improvement. METHODS: A qualitative study with 20 semi-structured interviews of doctors, nurses and ambulance personnel representing a wide range in experience and formal education, reflecting the different compositions of crews performing interhospital transports was conducted. A systematic text condensation of the interviews was performed to describe personal experiences and values. RESULTS: Few interviewees reported special adverse events when asked. Instead they chose to describe more general characteristics of the working environment, their own positive emotions or fears and the strengths and weaknesses of the organizational system. The prehospital working environment was described as different from the in-hospital environment. The personnel experienced being on their own during transports, lack of procedures and checklists and often no systematic education or demanded preparedness for participating. The resident doctors described pressure from elderly colleagues to participate in the transports. At the same time, all interviewees reported a self-interest in participating in these transports. CONCLUSIONS: Safe interhospital transports of the critically ill patients are challenged by the characteristics of the out of hospital environment. The transports are described as potentially unsafe for both patients and personnel. Systematic education is warranted, highlighting the use of checklists and special educational programs in prehospital critical care medicine. The strong personal interest to participate in these transports may serve as a barrier against changing todays system. To ensure the right level of competence and safety for each unique patient, it is imperative to standardize the interhospital transports on a national level, built on consensus from experienced prehospital personnel. TRIAL REGISTRATION: The trial is approved and registered by the local representative for the Norwegian Data Protection Authority as trial 13-7751.

A patient with solid gynecologic cancer causing lactic acidosis, severe hypercalcemia, and hypoglycemia.

Though rare in cervical cancer patients, paraneoplastic syndrome usually presents with several endocrine and hormonal symptoms. Knowledge of the pathophysiology that underlies these abnormalities is beneficial to diagnosis and treatment. An interdisciplinary approach and test analysis prior to initiating specific treatment is recommended, though prognosis appears poor in advanced cases.
