This is a case report of a 35-year-old female with acute intermittent porphyria who presented for elective vagotomy and pyloroplasty. The diagnosis of porphyria was made two years previously when she developed acute abdominal pain and lower motor neurone paralysis following ingestion of a barbiturate. The urine porphobilinogen test was positive. The patient had no other acute attack of porphyria and had not had a previous anaesthetic. Anaesthesia was induced with etomidate 0.3 mg X kg-1 IV. Muscle relaxation was obtained with pancuronium 6 mg IV and ventilation was mechanically controlled. Intraoperative analgesia was with 66 per cent nitrous oxide in oxygen and intermittent doses of fentanyl. The patient was stable during anaesthesia and surgery. The postoperative period was uneventful and patient did not have an acute attack of porphyria. This experience suggests that etomidate is safe for intravenous induction of anaesthesia in acute intermittent porphyria. However, reports of its use in more patients with this disease will be necessary before a final conclusion can be made.

During a twelve-month period, 416 children with acute abdominal pain required emergency admission to Southampton General Hospital; 46% had operations. Appendicitis was the commonest organic cause of acute abdominal pain identified (31%). Constipation (9%) can present as acute abdominal pain simulating appendicitis. All children should have a urine sample examined microscopically and the finding of significant pyuria is suggestive, but not diagnostic, of a urinary tract infection (7%). Mesenteric adenitis, which can only be diagnosed with certainty at laparotomy, was less common (4%). Despite careful clinical assessment and follow up, 45% of children in this series remained undiagnosed. Sedation but not analgesia may assist in the diagnosis of the acute abdomen in children.

Despite physiological advances and recent progress in pain relief, early analgesia for patients with acute abdominal pain is not a conventional endpoint. In clinical practice, priority is often given to diagnosis and management decisions. There are few controlled trials to settle the issue and opinions are still divided. recent studies suggest than early and effective analgesia in acute abdomen does not interfere with diagnosis, and even facilitates initial examination. Various modes of analgesia can be considered.

A prospective audit of 100 emergency admissions was carried out to determine local surgical practice for analgesia administration in patients with acute abdominal pain. The main outcome measure investigated was waiting time for analgesia and how this was influenced by (i) severity of pain, (ii) clinical diagnosis, (iii) clinical setting. The data were correlated with the results of a questionnaire on timing of analgesia. Forty percent of patients received analgesia within 1 h, 17% between 1-2 h, and 43% 2-22 h after admission. Mean waiting time was 2.3 h with severe pain (n = 84) vs. 6.3 h with moderate pain (n = 16, p < 0.0001, Mann-Whitney). Clinical diagnosis did not influence timing of analgesia. Fifty-seven per cent received analgesia in the Accident and Emergency (A&E) department with a mean wait of 60 min, whereas 43% admitted to the ward without analgesia in the A&E department waited an average of 5.7 h for pain medication (p < 0.0001; Mann-Whitney U-test). This was at variance with local surgical opinion that favoured early analgesia administration (yes-88%), in the absence of a firm diagnosis (yes-79%), although 38% stated that analgesia might mask physical signs. In conclusion, a substantial cohort of patients with acute abdominal pain (43%) wait too long for analgesia. Delays are due to omission of analgesia in A&E, and reluctance of junior staff to administer analgesia for fear of masking physical signs. Clinical guidelines for pain medication in acute surgical emergencies are warranted.

Withholding administration of narcotic analgesia in patients with acute abdominal pain for fear of masking pathology is still pervasive in current medical practice. We reviewed all the prospective trials that investigated the safety, adverse affects, and ultimate outcome in patients with acute abdominal pain receiving narcotic analgesia within the emergency department (ED). No adverse outcomes or delays in diagnosis could be attributed to the administration of analgesia. Based on this research, we propose that it is safe and humane to administer narcotic pain relief to patients presenting to the ED with acute abdominal pain provided no contraindications exist.

The use of opioid analgesia for acute abdominal pain of unclear etiology has traditionally been thought to mask symptoms, alter physical exam findings, delay diagnosis, and increase morbidity and mortality. However, studies in children and adults have demonstrated that administering intravenous opioids to patients with acute abdominal pain induces analgesia but does not delay diagnosis or adversely affect diagnostic accuracy. This review discusses the effects of opioid administration on pain relief and diagnostic accuracy in children with moderate to severe acute abdominal pain who have been evaluated in the emergency department. We hold that current evidence supports the administration of opioids to children with acute abdominal pain, and future trials will help determine safe and effective timing and dosing related to opioid administration.

For drug therapy a differentiation of acute and chronic pain is essential. In emergency situations of acute abdominal pain a fast diagnosis is mandatory. Analgesia should be provided as soon as possible. The different groups of analgesics should be used according to their known effects, side effects and contraindications. Postoperative pain after abdominal surgery has to be considered as a special condition of acute abdominal pain. Main treatment options are non opioid analgesics and opioids. Opioids can be administered intravenously via patient controlled analgesia (PCA) devices. In major abdominal surgery neuroaxial analgesia, preferentially administered via an epidural catheter provides excellent pain relief with positive impact on gastrointestinal motility and patients' recovery. Because of difficulties to allocate chronic abdominal pain to a specific organ, causal treatment often turns out to be difficult. Peripheral and central sensitization, as well as an alteration of the endogenous pain modulation comes to the fore in these chronic pain conditions. Co-analgesics like anticonvulsants and antidepressants are utilized to reduce sensitization and improve the endogenous pain modulating system. Non drug approaches and alternative treatment options might be useful. In contrast, orally or transcutaneously administered opioids are the principal corner stone for the treatment of cancer pain.

Appropriate pain therapy prior to diagnosis in patients with acute abdominal pain remains controversial. Several recent studies have demonstrated that pain therapy does not negatively influence either the diagnosis or subsequent treatment of these patients; however, current practice patterns continue to favour withholding pain medication prior to diagnosis and surgical treatment decision. A systematic review of PubMed, Web-of-Science and The-Cochrane-Library from 1929 to 2011 was carried out using the key words of 'acute', 'abdomen', 'pain', 'emergency' as well as different pain drugs in use, revealed 84 papers. The results of the literature review were incorporated into six sections to describe management of acute abdominal pain: (1) Physiology of Pain; (2) Common Aetiologies of Abdominal Pain; (3) Pre-diagnostic Analgesia; (4) Pain Therapy for Acute Abdominal Pain; (5) Analgesia for Acute Abdominal Pain in Special Patient Populations; and (6) Ethical and Medico-legal Considerations in Current Analgesia Practices. A comprehensive algorithm for analgesia for acute abdominal pain in the general adult population was developed. A review of the literature of common aetiologies and management of acute abdominal pain in the general adult population and special patient populations seen in the emergency room revealed that intravenous administration of paracetamol, dipyrone or piritramide are currently the analgesics of choice in this clinical setting. Combinations of non-opioids and opioids should be administered in patients with moderate, severe or extreme pain, adjusting the treatment on the basis of repeated pain assessment, which improves overall pain management.

The National Acute Porphyria Service (NAPS) provides acute care support and clinical advice for patients in England with active acute porphyria requiring haem arginate treatment and patients with recurrent acute attacks.This audit examined the benefits and complications of regular haem arginate treatment started with prophylactic intent to reduce the frequency of recurrent acute attacks in a group of patients managed through NAPS. We included 22 patients (21 female and 1 male) and returned information on diagnosis, indications for prophylactic infusions, frequency and dose, analgesia, activity and employment and complications including thromboembolic disease and iron overload.The median age at presentation with porphyria was 21 years (range 9-44), with acute abdominal pain as the predominant symptom. Patients had a median of 12 (1-400) attacks before starting prophylaxis and had received a median of 52 (0-1,350) doses of haem arginate. The median age at starting prophylaxis was 28 years (13-58) with a median delay of 4 years (0.5-37) between presentation and prophylaxis. The frequency of prophylactic haem arginate varied from 1 to 8 per month, and 67% patients were documented as having a reduction in pain frequency on prophylaxis. Only one patient developed clinically significant iron overload and required iron chelation, but the number of venous access devices required varied from 1 to 15, with each device lasting a median of 1.2 years before requiring replacement. Six patients stopped haem arginate and in three this was because their symptoms had improved. Prophylactic haem arginate appears to be beneficial in patients with recurrent acute porphyria symptoms, but maintaining central venous access may prove challenging.

Introduction and aim Pain is a frequent symptom in emergency patients and opioids are commonly used to treat it at emergency departments and at pre-hospital settings. The aim of this systematic review is to examine the efficacy and safety of parenteral opioids used for acute pain in emergency medicine. Method Qualitative review of randomized controlled trials (RCTs) on parenteral opioids for acute pain in adult emergency patients. Main outcome measures were: type and dose of the opioid, analgesic efficacy as compared to either placebo or another opioid and adverse effects. Results Twenty double-blind RCTs with results on 2322 patients were included. Seven studies were placebo controlled. Majority of studies were performed in the emergency department. Only five studies were in prehospital setting. Prehospital studies Four studies were on mainly trauma-related pain, one ischemic chest pain. One study compared two different doses of morphine in mainly trauma pain showing faster analgesia with the larger dose but no difference at 30 min postdrug. Three other studies on the same pain model showed equal analgesic effects with morphine and other opioids. Alfentanil was more effective than morphine in ischemic chest pain. Emergency department studies Pain models used were acute abdominal pain seven, renal colic four, mixed (mainly abdominal pain) three and trauma pain one study. Five studies compared morphine to placebo in acute abdominal pain and in all studies morphine was more effective than placebo. In four out of five studies on acute abdominal pain morphine did not change diagnostic accuracy, clinical or radiological findings. Most commonly used morphine dose in the emergency department was 0.1 mg/kg (five studies). Other opioids showed analgesic effect comparable to morphine. Adverse effects Recording and reporting of adverse effects was very variable. Vital signs were recorded in 15 of the 20 studies (including all prehospital studies). Incidence of adverse effects in the opioid groups was 5-38% of the patients in the prehospital setting and 4-46% of the patients in the emergency department. Nausea or vomiting was reported in 11-25% of the patients given opioids. Study drug was discontinued because of adverse effects five patients (one placebo, two sufentanil, two morphine). Eight studies commented on administration of naloxone for reversal of opioid effects. One patient out of 1266 was given naloxone for drowsiness. Ventilatory depression defined by variable criteria occurred in occurred in 7 out of 756 emergency department patients. Conclusion Evidence for selection of optimal opioid and dose is scarce. Opioids, especially morphine, are effective in relieving acute pain also in emergency medicine patients. Studies so far are small and reporting of adverse effects is very variable. Therefore the safety of different opioids and doses remains to be studied. Also the optimal titration regimens need to be evaluated in future studies. The prevention and treatment of opioid-induced nausea and vomiting is an important clinical consideration that requires further clinical and scientific attention in this patient group.
