PURPOSE: Despite current literature, data on the most effective sedation and best patient outcomes are insufficient for providing recovery time recommendations for elderly patients undergoing colonoscopy with sedation. We sought to identify the best sedation practice for shorter recovery times. Therefore, a study was conducted to examine recovery times among patients older than 65 years undergoing elective colonoscopy with intravenous sedation with either propofol or the combination of midazolam/fentanyl...

BACKGROUND: Postoperative agitation or confusion is one of the symptoms of hyperactive delirium in elderly patients. We retrospectively evaluated the incidence of postoperative abnormal psychomotor behaviour in elderly surgical patients according to the use of different intraoperative sedative agents: dexmedetomidine vs. propofol. METHODS: The medical records of 855 elderly patients, who underwent orthopaedic surgery with regional anaesthesia between July 2012 and September 2015, were divided into two groups-the dexmedetomidine group (n=263) and the propofol group (n=592)-and evaluated...

Post-operative cognitive dysfunction (POCD) is a commonly seen postoperative complication in elderly patients and its underlying mechanisms are still unclear. Autophagy, a degradation mechanism of cellular components, is required for cell survival and many physiological processes. Although propofol is one of the most commonly used intravenous anesthetics, investigations into its mechanisms and effects on cognition in aged rodents are relatively scarce. In this study, we evaluate the influence of propofol on learning and memory, and identify the potential role of hippocampal autophagy in propofol-induced cognitive alterations in aged rats...

BACKGROUND: Peripheral nerve block combined with general anesthesia is a preferable anesthesia method for elderly patients receiving hip arthroplasty. The depth of sedation may influence patient recovery. Therefore, we aimed to investigate the influence of peripheral nerve blockade and different intraoperative sedation levels on the short-term recovery of elderly patients receiving total hip arthroplasty. METHODS: Patients aged 65 years and older undergoing total hip arthroplasty were randomized into three groups: a general anesthesia without lumbosacral plexus block group, and two general anesthesia plus lumbosacral plexus block groups, each with a different level of sedation (light or deep)...

INTRODUCTION: Trochanteric hip fractures in elderly patients with osteoporosis are commonly caused by low energy trauma. The cardioversion therapy is an extremely rare cause of this type of fracture. PRESENTATION OF CASE: We report the case of a woman with hip fracture after cardioversion. DISCUSSION: We discuss the production mechanism of this injury and the importance of the care of the osteoporotic bone under these therapies. CONCLUSION: The propofol sedation should be complemented with skeletal muscle relaxants in the cardioversion therapy to avoid hip fracture in select patients with osteoporosis...

We report the case of a 37-year-old female patient who required 22 surgeries following a pedestrian versus car accident. She was enrolled in a clinical study investigating emergence from anesthesia. In 10 of her 22 surgeries, we assessed her cognitive status in the postanesthesia care unit (PACU) using the Confusion Assessment Method. We observed PACU delirium in all 4 cases in which the patient received sevoflurane, but only in 1 of 6 cases in which she received propofol. The patient showed EEG α-band activity similar to that of an elderly patient who may reflect a greater risk of PACU delirium...

INTRODUCTION: Opioids are widely used in conjunction with local anesthetics as they permit the use of lower dose of local anesthetics while providing adequate anesthesia and analgesia. It both provides adequate anesthesia as well as lower drug toxicity neuraxial administration of opioids in conjunction with local anesthetics improves the quality of intraoperative analgesia and prolongs the duration of postoperative analgesia. Bupivacaine is the most commonly used drug for subarachnoid block due to its lesser side effects...
