RESUMEN
“Chronic pain after spinal surgery” (CPSS) is a nonspecific term for cases in which the end result of surgery generally does not meet the preoperative expectations of the patient and surgeon. This term has replaced the previous term i.e., failed back surgery syndrome. CPSS is challenging for both patients and doctors. Despite advancements in surgical techniques and technologies, a subset of patients continue to experience persistent or recurrent pain postoperatively. This review provides an overview of the multimodal management for CPSS, ranging from conservative management to revision surgery. Drawing on recent research and clinical experience, we aimed to offer insights into the diverse strategies available to improve the quality of life of CPSS patients.
RESUMEN
Background@#Monitoring the oxygenation status is crucial during general anesthesia to ensure patient safety. Although noninvasive pulse oximetry is commonly used to monitor percutaneous oxygen saturation (SpO2), it may not accurately reflect changes in oxygen partial pressure when the latter is excessively high or low. The oxygen reserve index (ORi) provides real-time information about the oxygen reserve status.Case: We present a case of successful management of subglottic stenosis using balloon bronchoscopy in an infant with a left ventricular assist device implantation under ORi monitoring to predict hypoxemia during the surgical procedure. @*Conclusions@#Utilizing ORi monitoring during anesthesia for procedures involving apnea in critically ill infants can help predict impending desaturation before a drop in SpO2 occurs, allowing anesthesiologists to effectively anticipate and manage the apnea period. Continuous ORi monitoring offers valuable insights during surgical procedures, especially in infants with compromised respiratory and cardiovascular functions.

BACKGROUND: Sedation during epidural anesthesia can reduce patients' anxiety and discomfort. Dexmedetomidine has sedative, hypnotic, and analgesic effects, with minimal respiratory depression. However, the use of dexmedetomidine is associated with prolonged recovery. This study investigated the optimal dose of intravenous dexmedetomidine for proper sedation with minimal recovery time in epidural anesthesia. METHODS: Sixty-three patients (American Society of Anesthesiologists physical status I/II) were randomized into two groups. Following epidural anesthesia, a loading dose (1 µg/kg) of dexmedetomidine was administered for 10 min followed by maintenance infusion as follows: Group A (n = 32; dexmedetomidine 0.6 µg/kg/h) and Group B (n = 31; dexmedetomidine 1.0 µg/kg/h). Heart rate, blood pressure, and bispectral index score (BIS) were recorded during surgery. The length of stay and modified Aldrete score (MAS) were measured in the postanesthesia care unit (PACU). RESULTS: Length of stay in the PACU was longer in Group B than in Group A (P < 0.05). The MAS was higher in Group A after 30 min in the PACU (P < 0.05). The BIS did not significantly differ between the two groups from baseline to 150 min after infusion of dexmedetomidine. BIS values were significantly higher in Group A at 160 min (P < 0.05). The mean arterial pressure in Group B was significantly lower in the PACU. CONCLUSIONS: Length of stay in the PACU was longer in Group B than in Group A (P < 0.05). The MAS was higher in Group A after 30 min in the PACU (P < 0.05). The BIS did not significantly differ between the two groups from baseline to 150 min after infusion of dexmedetomidine. BIS values were significantly higher in Group A at 160 min (P < 0.05). The mean arterial pressure in Group B was significantly lower in the PACU.
