Laparoscopic surgery for gastric reduction is frequently associated with high levels of postoperative pain. Postoperative pain is very often treated with opioids. However large doses of opioids can result in respiratory depression with hypoxemia especially in high risk patients with obstructive sleep apnea. since a large group of patients undergoing surgery for gastric reduction surgery also have obstructive sleep apnea, it is expected that these patients are also at high risk for postoperative respiratory depression and hypoxemia. Intraoperative ketamine has been used as an effective multimodal agent to reduce postoperative pain. However, ketamine alone has not been examined to improve postoperative pain outcomes in patients undergoing gastric reduction surgery. More importantly, it is unknown if the use of intraoperative ketamine can lead to better overall quality of recovery in the same patient population. In addition, ketamine has been shown to improve ventilation but it remains to be determined if the intraoperative use of ketamine will result in less postoperative hypoxemic events. The main objective of the current investigation is to examine the effect of intraoperative ketamine on postoperative quality of recovery after gastric reduction surgery. The investigators hypothesize that subjects receiving ketamine will have a greater global quality of recovery score than the ones receiving saline. Read Less

The purpose of this study is to determine whether a low-dose ketamine infusion can be used as the main intra-operative analgesic in different burn patients, and thereby reduce the total intra-operative opioid requirement. Secondary objectives are to determine whether this low-dose ketamine infusion will lengthen the amount of time to the first narcotic given in the recovery room or ICU, and whether pain scores for awake patients will be lower post-operatively.

Ketamine is an IV anesthetic with non-opioid analgesic properties that has been shown to reduce pain while also decreasing intraoperative and postoperative opioid requirements when used in subanesthetic doses after a variety of surgical procedures.1 It is a non-competitive antagonist of N-methyl-D-aspartate (NMDA) receptors, and by this mechanism ketamine is believed to block the development of central sensitization and wind-up phenomenon,2,3 which may be helpful in preventing acute and chronic pain after repetitive insults. In a systematic review of ketamine as an adjuvant to opioid analgesia, low-dose ketamine was found to be a useful addition to standard postoperative pain management practice with opioids in 54% of studies.1 The studies that did not show a significant effect were in patient populations with low opioid requirements. Therefore, it has been suggested that future clinical trials be focused on patient populations with significant post-operative pain, such as spine surgery and major orthopedic surgery not amenable to regional analgesia, and postoperative pain in patients on chronic preoperative opioid therapy.1 There are few studies examining outcomes after ketamine in the perioperative period after spine surgery. Loftus et al randomized patients with a history of chronic preoperative opioid use (i.e., daily opiate use for at least 6 weeks) to intraoperative ketamine versus placebo and found a 30% reduction in morphine consumption at 48 hours and an approximately 25% reduction in visual analog scale (VAS) pain score in the post anesthesia care unit and at 6 weeks.4 Although this study provided evidence that there may be reduction in long-term postoperative pain, additional studies are needed to provide evidence that this effect is sustained beyond the 6-week period. We are interested in examining ketamine more closely in spine surgery because this patient population experiences significant postoperative pain that may be difficult to control due to preoperative opioid use (i.e., opioid tolerance). The investigators chose to study ACDF patients specifically because it is a common spine procedure throughout the United States and the patients have significant opioid requirements postoperatively. In a study examining the effects of the low dose ketamine for postoperative IV PCA fentanyl after cervical and lumbar surgery, patients in the placebo group (and thus only receiving fentanyl PCA) reported mean VAS scores of 4-5 with movement while receiving opioids.5 Further, while previous studies have shown an opioid-sparing effect of ketamine as measured by opioid consumption and a decrease in pain as measured by VAS scores, no study to our knowledge has examined quality of recovery after intraoperative ketamine infusion. The Quality of recovery (QoR-40) score was developed by Myles et al to assess quality of recovery after anesthesia based on forty questions in five dimensions,6 and this score has been shown to be a reliable and valid outcome for patients undergoing both spine and cranial surgery.7 QoR-40 is also of interest because it should be able to provide a global assessment of the possible benefit or harm of using ketamine in patients by simultaneously characterizing the detrimental side effects as well as the positive benefits of ketamine when used as an infusion at subanesthetic levels (studies thus far have shown that there are minimal side effects such as hallucinations).1,4 Significance: Previous studies have shown an opioid-sparing effect of ketamine, however further research is warranted in patients whose pain may be difficult to control and whether this effect is sustained. ACDF patients experience significant pain post-operatively, and ketamine may improve their quality of recovery due to its opioid-sparing effects and prevention of chronic pain. Further, patient centered outcomes as measured by the QoR-40 have not been reported in the literature when ketamine, or other opioid sparing anesthetics, have been administered. This study will not only determine if the "moderate" dose of ketamine is beneficial or detrimental to the recovery of patients but also whether it can improve long term patient function, presumably by decreasing central pain sensitization. In addition, this study will set the stage for further RCT's examining other analgesic strategies in cervical spine surgery patients (i.e., intraoperative lidocaine infusions, volatile anesthetic vs. propofol as the primary hypnotic, COX-2 inhibitors, pregabalin, etc.). The overall goal would be to develop a multi-faceted regimen that decreases the postoperative inpatient opioid requirements of these patients and may facilitate long term recovery. The research questions:Does ketamine improve the quality of recovery at 24 hours after anterior cervical discectomy and fusion (ACDF)? The hypothesis: the investigators hypothesize that ketamine will improve the quality of recovery after ACDF surgery Read Less

The study question: Does the SNAP-Index (SI) correlates better with the OASS than the BIS Monitor during sedation with ketamine? The study hypothesis: Since the SNAP II monitor seems to be more responsive during emergence of anesthesia, it will have a better correlation with the OASS than the BIS monitor with the use of ketamine.

Procedures performed under sedation have the same severity in regards to morbidity and mortality as procedures performed under general anesthesia1. The demand for anesthesia care outside the operating room has increased tremendously and it poses, according to a closed claim analysis, major risks to patients. Both closed claim analysis identified respiratory depression due to over sedation as the main risk to patients undergoing procedures under sedation. The major problem is that hypoventilation is only detected at very late stages in patients receiving supplemental oxygen. Besides the respiratory effects of hypoventilation, hypercapnia can also lead to hypertension, tachycardia, cardiac arrhythmias and seizures. The incidence of anesthetized patients with obstructive sleep apnea has increased substantially over the last years along with the current national obesity epidemic. These patients are at increased risk of hypoventilation when exposed to anesthetic drugs. The context of the massive increase in procedural sedation and the extremely high prevalence of obstructive sleep apnea poses major respiratory risks to patients and it may, in a near future, increase malpractice claims to anesthesiologists. The development of safer anesthesia regimen for sedation are, therefore, needed. The establishment of safer anesthetics regimen for sedation is in direct relationship with the anesthesia patient safety foundation priorities. It addresses peri-anesthetic safety problems for healthy patient's. It can also be broadly applicable and easily implemented into daily clinical care. Ketamine has an established effect on analgesia but the effects of ketamine on ventilation have not been clearly defined. The investigators have demonstrated that the transcutaneous carbon dioxide monitor is accurate in detecting hypoventilation in patients undergoing deep sedation. Animal data suggest that when added to propofol in a sedation regimen, ketamine decreased hypoventilation when compared to propofol alone. It is unknown if ketamine added to a commonly used sedative agent (propofol) and fentanyl can decrease the incidence and severity of hypoventilation in patients undergoing deep sedation. The investigators hypothesize that patients receiving ketamine, propofol and fentanyl will develop less intraoperative hypoventilation than patients receiving propofol and fentanyl. The investigators also hypothesize that this effect will be even greater in patients with obstructive sleep apnea than patients without obstructive sleep apnea. Significance: Respiratory depression due to over sedation was identified twice as the major factor responsible for claims related to anesthesia. The high prevalence of obstructive sleep apnea combined with more complex procedures done in outpatient settings can increase physical risks to patients and liability cases to anesthesiologists. The main goal of this project is to establish the effect of ketamine in preventing respiratory depression to patients undergoing procedures under deep sedation using propofol and fentanyl. If the investigators can confirm our hypothesis, our findings can be valuable not only to anesthesiologist but also to other specialties (emergency medicine, gastroenterologists, cardiologists, radiologists) that frequently performed procedural sedation. The research questions is; does the addition of ketamine prevent hypoventilation during deep sedation using propofol and fentanyl? The hypotheses of this study: Ketamine will prevent hypoventilation during deep sedation cases. Read Less
