简要总结
The main objective for investigators is to determine the prevalence of moderate to severe chronic pain in the adult population 6 months after consultation in the emergency department for acute pain (less than 7 days old) and severe pain assessed at admission and defined as greater than or equal to 6/10 by the numerical pain scale.
详细描述
The presence of pain is the most frequent reason for a patient to visit the emergency department. the investigators know that severe acute pain can be a risk factor for developing chronic pain.
Chronic pain is a symptom, devoid of biological utility, that persists despite the absence of nociceptive stimulus, even after a reasonable period of time that would have allowed the tissue lesion to heal. It is therefore a public health problem with a negative impact on patients' lives.
Chronic pain has been studied in anesthesia and surgery in recent years. In 2006, a study showed the appearance of chronic pain (incidence between 10-50%) in patients who had undergone routine surgery. On the other hand, few studies have looked at the occurrence of chronic pain in patients who came to the emergency department for acute pain.
It is in this context that the investigators find it relevant to assess the prevalence of moderate to severe chronic pain after an emergency department consultation for severe acute pain.
The physiological mechanisms of pain are better identified and the activation of N-methyl-D-aspartate (NMDA) receptors contributes to the onset of hyperalgesia. These receptors are activated under certain conditions, such as during intense and prolonged pain or exposure to high doses of opioids. In addition, the hyperalgesic effect of opioids is known and widely described in the literature. Finally, in the perioperative period, it is now accepted that the administration of a low dose of ketamine can combat these hyperalgesic effects thanks to its NMDA receptor inhibitory action. This effect may have an impact on pain at six months after surgery.

结局指标
主要结局
Determine prevalence of moderate to severe chronic pain in adult population 6 months after consultation in the emergency department for acute pain (less than 7 days old) and severe pain assessed at admission (defined ≥6/10 by the numerical pain scale)
时间窗: 6 month
The main judgment criteria is the presence of chronic pain, related to the pain that motivated the emergency department visit 6 months earlier, moderate to severe defined as pain evolving since the emergency department visit (6 months), experienced at least 2 times per week, and of intensity ≥ 4 on a numerical pain scale during the patient's last painful experience.
次要结局
- Evaluate whether there is an association between the prevalence of chronic pain at 6 months and pain management at the performance of a locoregional anaesthesia when the patient goes to the emergency department ;(6 month)
- Evaluate whether there is an association between the prevalence of chronic pain at 6 months and pain management in use of analgesic, which molecule when the patient goes to the emergency department ;(6 month)
- To compare the prevalence of chronic pain in patients who initially consulted for pain of traumatic or non-traumatic origin.(6 month)
- The type, characteristics and impact of pain at 6 months after admission to the emergency department.(6 month)
- Evaluate whether there is an association between the prevalence of chronic pain at 6 months and pain management in use of analgesic at which dose when the patient goes to the emergency department ;(6 month)
- Evaluate whether there is an association between the prevalence of chronic pain at 6 months and pain management at the performance of sedation when the patient goes to the emergency department ;(6 month)
- If patients with chronic pain at 6 months reconstructed more often than patients without chronic pain(6 month)
- Neuropathic characteristics of pain at 6 months(6 month)
- Quality of life 6 months after admission to the emergency department(6 month)
- Analgesic treatment at 6 months.(6 month)
