Purpose: Our aim in this study is to investigate efficacy of topical lidocaine spray for sedated esophagogastroduodenoscopy (EGD) in children. Methods: The endoscopy of children aged between 3-18 years who underwent EGD in our endoscopy unit. Intravenous (IV) midazolam and ketamine were used for sedation. Prior to sedation, endoscopy nurse applied topical lidocaine 10% with pump spray at 1 mg/kg dose in group 1, and distilled water via identically scaled pump spray in group 2, in a double blinded fashion. Results: Sedation was not applied in 24.1% of the cases in topical lidocaine spray group (LS group) and in 5.7% of the cases in distilled water spray group (DS group). Gag reflex was observed in 6.5% of cases in LS group and 33.3% of cases in DS group (p=0.024), increased oral secretion was observed in 9.3% of cases in LS group and 51.7% of cases in DS group (p=0.038), sore throat was observed in 3.7% of cases in LS group and 35.6% of cases in DS group (p=0.019) and the difference was statistically significant. Conclusion: The study showed that topical pharyngeal lidocaine reduces both requirement and amount of IV sedation before EGD in children and sore throat, gag reflex and decreased oral secretion increase.

The combination of oxycodone and naloxone is useful for cancer pain management. Naloxone, as a pure opioid antagonist, cannot be used simultaneously with opioids. However, owing to its low bioavailability, it can be used in an oral composite formulation. We present the case of a 55-year-old man with gastric cancer who experienced severe opioid withdrawal syndrome (OWS) triggered by oxycodone/naloxone that was successfully managed with dexmedetomidine. He had been in a stable condition on intravenous morphine to alleviate cancer pain. Intravenous morphine was switched to oral oxycodone/naloxone for discharge from the hospital. The patient suddenly developed restlessness, heartburn, and violent behavior 30 minutes after taking oxycodone/naloxone. We attempted sedation with midazolam and propofol, but paradoxical agitation and desaturation occurred. Next, we tried dexmedetomidine and the patient showed a decreased heart rate and reduced agitation. The patient was eventually stabilized by increasing the dose of dexmedetomidine. This report informs clinicians of the possibility of OWS when switching from opioids to oxycodone/naloxone, which can be overcome with the appropriate use of sedatives and dexmedetomidine depending on the patient's condition.

Drug-induced sleep endoscopy (DISE) is used to identify areas of upper airway obstruction, which occurs when patients with obstructive sleep apnea (OSA) snore. DISE enables effective diagnosis and appropriate treatment of the obstruction site. Among surgical treatment methods for OSA, maxillomandibular advancement surgery (MMA) is performed to move a jaw forward; the surgery has a high success rate for OSA treatment. In DISE, anesthetics such as propofol and midazolam must be administered to induce snoring while the patient is deeply sedated for an accurate diagnosis to be made. When inducing deep sedation in a patient with OSA, airway obstruction may increase, causing oxygen saturation to drop; airway interventions are necessary in such cases. Effective DISE and MMA surgery can be performed by administering propofol through target-controlled infusion while monitoring the bispectral index (BIS).

Background: The purpose of this study was to compare the availability of propofol and fentanyl (P + F) with diazepam and morphine (D + M) for intravenous conscious sedation during third molar surgery. Methods: Forty patients without systemic disease were operated under IV conscious sedation administered by either of the two techniques. Monitoring consisted of continuous observation of pulse rate, blood pressure, oxygen saturation, and the respiratory rate and were recorded every 15 minutes. Cooperation score was measured 5 and 15 minutes after induction of IV sedation. Following the operation, the surgeon and patients completed questionnaires including pain visual analog scale, amnesia, and side effects. Results: The P + F group was significantly more cooperative than the D + M group. The side effects of D + M group included pain on injection, nausea/vomiting and abdominal pain. The side effects of P + F group included talkativeness, nausea/vomiting, temporary apnea, pain on injection and vertigo. Conclusions: In this study, there were following benefits in the P + F group; more cooperative status and less pain perception. But respiratory depression developed in some patients.

In sedation via the submucosal route, the drug is administered through the maxillary buccal submucosa. It is time saving, effective, and safe. Patients with autism, a mental disorder, often find it hard to make relationships with other people. These patients display a strong resistance to dental treatment and sedation. This study reports a successful case of behavioral management during dental treatment, using sedation via the submucosal route. The patient was strongly resistant to sedation via the oral, intramuscular, and intravenous routes. The drug used was 9 mg (0.1 mg/kg) of midazolam. Through this case report, we reaffirm the significance of sedation via the submucosal route, and expect that it will be used more frequently for patients with autism, who display behaviors that are difficult to manage, patients with other disabilities, and children.

Difficult airway management including difficult intubation, difficult ventilation and difficult mask ventilation is a life threatening issue during anesthesia care. A 23-year-old woman with Treacher Collins syndrome was scheduled for distraction osteogenesis. She had hypoplasia of mandible and malar bone, bilateral deformities of auricles with partial deafness and antimongoloid slant of the palpebral fissures. A 56-year-old woman with mandibular hypoplasia due to childhood trauma was scheduled for distraction osteogenesis. She had a history of difficult intubation. We anticipated a difficult intubation and ventilation. Fiberoptic bronchoscopic guided awake intubation was selected for anesthesia induction. After intravenous injection of midazolam and remifentanil, 10% lidocaine pump spray on the pharyngolarynx with a direct laryngoscope and on the nasal canal. However fiberoptic bronchoscopic guided awake intubation was failed due to severe gag reflex. After intravenous injection of propofol and remifentanil using the target controlled infusion (TCI), mask ventilation was easily performed and, after intravenous injection of vecuronium, fiberoptic bronchoscopic guided intubation was easily performed using a wire reinforced endotracheal tube. The operation was completed successfully without any adverse events.

Dentists often sedate patients in order to reduce their dental phobia and stress during dental treatment. Sedatives are administered through various routes such as oral, inhalation, and intravenous routes. Intravenous administration has the advantage of rapid onset of action, predictable duration of action, and easy titration. Typically, midazolam, propofol or dexmedetomidine are used as intravenous sedatives. Administration of these sedatives via infusion by using a syringe pump is more effective and successful than infusing them as a bolus. However, during intravenous infusion of sedatives or opioids using a syringe pump, fatal accidents may occur due to the clinician's carelessness. To prevent such risks, smart syringe pumps have been introduced clinically. They allow clinicians to perform effective sedation by using a computer to control the dose of the drug being infused. To ensure patient safety, various alarm features along with a drug library, which provides drug information and prevents excessive infusion by limiting the dose, have been added to smart pumps. In addition, programmed infusion systems and target-controlled infusion systems have also been developed to enable effective administration of sedatives. Patient-controlled infusion, which allows a patient to control his/her level of sedation through self-infusion, has also been developed. Safer and more successful sedation may be achieved by fully utilizing these new features of the smart pump.
