Brief summary
Cranio-cervical instability (CCI) has been well identified in diseases regarding connective tissue, such as Ehlers-Danlos Syndrome/Hipermobility Type (EDS-HT). These patients frequently suffer from severe widespread pain with very difficult management and control. Chronic neuroinflamation, opioid-induced hyperalgesia, and central sensitization phenomena may explain this complex painful condition. A retrospective, observational, consecutive case series study is designed to determine if opioid-free anesthetic management shows a reduction in postoperative pain and opioid rescues needs in comparison with opioid-based anesthesia management for patients with EDS-HT undergoing crano-cervical fixation.
Detailed description
Cranio-cervical instability (CCI) has been well identified in diseases regarding connective tissue, such as Ehlers-Danlos Syndrome/Hipermobility Type (EDS-HT). These patients frequently suffer from severe widespread pain with very difficult management and control. Chronic neuroinflamation, opioid-induced hyperalgesia, and central sensitization phenomena may explain this complex painful condition. A retrospective, observational, consecutive case series study is designed to determine if opioid-free anesthetic management shows a reduction in postoperative pain and opioid rescues needs in comparison with opioid-based anesthesia management for patients with EDS-HT undergoing craneo-cervical fixation. Main Aim: To determine if the administration of opioid-free anesthesia with propofol, lidocaine, ketamine, and dexmedetomidine shows reduction of postoperative pain, and postoperative needs of opioids rescue in patients undergoing CCF. Secondary Aims: * To determine if the administration of opioid-free anesthesia in patients undergoing CCF, and postoperative Lidocaine, Ketamine, and Dexmedetomidine infusions can reduce the preoperative needs of opioids treatment at discharge time. * To determine if the administration of opioid-free anesthesia in patients undergoing CCF reduces the postoperative gastrointestinal complications. * To determine if the administration of postoperative Lidocaine, Ketamine, and Dexmedetomidine infusions in patients underwent CCF can reduce the preoperative needs of postoperative anxiolytic treatment.
