The effects of ketamine administered per nasus (PN) or per rectum (PR) as pre-anesthetic medication for day surgery was studied in 70 ASA class I children with age ranging from 6 months to 6 years. Before study they were divided into 3 groups. Group A (n = 25) received no premedicant, while group B (n = 25) and group C (n = 20) received ketamine 6 mg/kg PR and 3 mg/kg PN as premedicant respectively. It was demonstrated that patients in group B and group C accepted the facemask during induction of anesthesia more willingly and peacefully than those in group A. In group B and group C there was accompaniment of analgesic effect seen postoperatively. The incidence of adverse reactions (nausea, vomiting, laryngospasm, salivation, respiratory depression) was low following the use of PR or PN ketamine although the children in these two groups emerged more belatedly from anesthesia and stayed in the post-anesthetic recovery room (PARR) for a longer time than in group A.

The authors performed a randomized, prospective trial comparing enflurane, halothane, and isoflurane (each administered with nitrous oxide) to establish which inhaled anesthetic produced the fewest complications and the most rapid induction of anesthesia for children undergoing general anesthesia for diagnostic procedures as oncology outpatients. Sixty-six children, ranging from 8 months to 18 years, underwent a total of 124 anesthetics. Induction of anesthesia (time from placement of facemask to beginning of skin preparation) was faster with halothane (2.7 +/- 1.0 min, mean +/- SD, n = 46) than with enflurane (3.2 +/- 0.8 min, n = 43) or isoflurane (3.3 +/- 1.2 min, n = 35). Emergence from anesthesia (time from completion of the procedure to spontaneous eye opening) was more rapid with enflurane (4.7 +/- 4.4 min) than with halothane (6.2 +/- 4.5 min) or isoflurane (6.2 +/- 3.9 min). Total time from the start of procedure until discharge was longer with isoflurane (25.1 +/- 6.8 min) than with enflurane (21.5 +/- 8.6 min) or halothane (22.3 +/- 7.6 min). During induction, the incidence of laryngospasm was greatest with isoflurane (23%) and the incidence of excitement least with halothane (13%). During the maintenance of, emergence from, and recovery from anesthesia, coughing occurred most frequently with isoflurane. During the recovery period, headache occurred most frequently with halothane (9%); there were no significant differences in the incidence of nausea, vomiting, hunger, or depressed effect. The authors conclude that the rapid induction and minimal airway-related complications associated with halothane anesthesia make it an excellent anesthetic agent for pediatric patients undergoing short diagnostic procedures.

Induction, emergence and recovery characteristics were compared during sevoflurane or halothane anaesthetic in a large (428) multicentre, international study of children undergoing elective inpatient surgical procedures. Two hundred and fourteen children in each group underwent inhalation induction with nitrous oxide/oxygen and sevoflurane or halothane. Incremental doses of either study drug were added until loss of eyelash reflex was achieved. Steady state concentrations of anaesthesia were maintained until the end of surgery when anaesthetic agents were terminated simultaneously. Time variables were recorded for induction, emergence and the first need for analgesia in the recovery room. In addition, in 86 of the children in both groups, venous blood samples were drawn for plasma fluoride levels during and after surgery. There was a trend toward smoother induction (induction of anaesthesia without coughing, breath holding, excitement laryngospasm, bronchospasm, increased secretion, and vomiting) in the sevoflurane group with faster induction (2.1 min vs 2.9 min, P = 0.037) and rapid emergence times (10.3 min vs 13.9 min, P = 0.003). Among the children given sevoflurane, 2% developed bradycardia compared with 11% in the halothane group. Postoperatively, 46% of the children in the halothane group developed nausea and or vomiting versus 31% in the sevoflurane group (P = 0.002). Two children in the halothane group developed cardiac dysrhythmia and were dropped from the study. In addition, a child in the halothane group developed malignant hyperthermia, received dantrolene, and had an uneventful recovery. Mean maximum inorganic fluoride concentration was 18.3 microM.l-1. The fluoride concentrations peaked within one h of termination of sevoflurane anaesthetic and returned rapidly to baseline within 48 h. This study suggests that sevoflurane may be the drug of choice for the anaesthetic management of children.

Complications of flexible bronchoscopy (FB) were prospectively evaluated during 1,328 diagnostic procedures in children, not in intensive care units. A total 92.8% of the procedures were performed in conscious patients under sedation and 7.2% under deep sedation. Supplementary oxygen was provided in approximately 80% of cases via endoscopic face mask (n=783) or nasal prongs (n=290). At least one complication was recorded in 91 cases (6.9%). Minor complications (n=69; 5.2%) included moderate and transient episodes of desaturation (n=15), isolated excessive coughing (n=22), excessive nausea reflex with coughing (n=20), transient laryngospasm (n=6) and epistaxis (n=6). Major complications (n=22; 1.7%) included oxygen desaturation to <90%, either isolated (n=10) or associated with laryngospasm (n=6), coughing (n=4), bronchospasm (n=1), and pneumothorax (n=1). Major complications involving oxygen desaturation were associated with age <2 yrs (13 of 529 versus 8 of 778) and laryngotracheal abnormalities (7 of 85 versus 14 of 1,222). The overall frequency of complications was similar in conscious (6.7%) but sedated patients and patients under deep (7.3%) sedation. However, the frequency of transient desaturation was significantly higher in children undergoing FB under deep sedation. Transient fever after bronchoalveolar lavage was observed in 52 of 277 cases (18.8%). Flexible bronchoscopy is a safe procedure with <2% major complications. Careful analysis of indications and clinical status for each patient, and proper anaesthesia and monitoring during the examination ensure that the procedure is successful, with a minimum of complications.

The aim of this study was to introduce a continuous monitoring of side effects related to sedation-analgesia in the field. A document was completed by physicians on board the ambulances for all prehospital interventions and checked daily by the medical staff. A total of 3605 interventions were evaluated over a 12-month period. Six hundred four patients undertook analgesia and/or sedation: group 1 (spontaneously breathing patients) n = 289 and group 2 (intubated-ventilated patients) n = 315. Sixty-four percent of patients received intravenous opioids in group 1. The anesthetic technique used for intubation was the rapid sequence induction in 70% of patients. Side effects were observed in 5.5% in group 1 (nausea: 2%, hypotension: 1%, hypoxemia: 1%) and 22% of patients in group 2 (hypotension-arrhythmia: 12%, cardiac arrest: 2%, difficult intubation: 5%, hypoxemia: 1%, pulmonary aspiration: 1%, laryngospasm/bronchospasm: 2%). No death was related to these medications. A close monitoring of side effects related to sedation-analgesia must be included in a quality program to improve patient safety in the field.

Hydrogen peroxide is an oxidising agent that is used in a number of household products, including general-purpose disinfectants, chlorine-free bleaches, fabric stain removers, contact lens disinfectants and hair dyes, and it is a component of some tooth whitening products. In industry, the principal use of hydrogen peroxide is as a bleaching agent in the manufacture of paper and pulp. Hydrogen peroxide has been employed medicinally for wound irrigation and for the sterilisation of ophthalmic and endoscopic instruments. Hydrogen peroxide causes toxicity via three main mechanisms: corrosive damage, oxygen gas formation and lipid peroxidation. Concentrated hydrogen peroxide is caustic and exposure may result in local tissue damage. Ingestion of concentrated (>35%) hydrogen peroxide can also result in the generation of substantial volumes of oxygen. Where the amount of oxygen evolved exceeds its maximum solubility in blood, venous or arterial gas embolism may occur. The mechanism of CNS damage is thought to be arterial gas embolisation with subsequent brain infarction. Rapid generation of oxygen in closed body cavities can also cause mechanical distension and there is potential for the rupture of the hollow viscus secondary to oxygen liberation. In addition, intravascular foaming following absorption can seriously impede right ventricular output and produce complete loss of cardiac output. Hydrogen peroxide can also exert a direct cytotoxic effect via lipid peroxidation. Ingestion of hydrogen peroxide may cause irritation of the gastrointestinal tract with nausea, vomiting, haematemesis and foaming at the mouth; the foam may obstruct the respiratory tract or result in pulmonary aspiration. Painful gastric distension and belching may be caused by the liberation of large volumes of oxygen in the stomach. Blistering of the mucosae and oropharyngeal burns are common following ingestion of concentrated solutions, and laryngospasm and haemorrhagic gastritis have been reported. Sinus tachycardia, lethargy, confusion, coma, convulsions, stridor, sub-epiglottic narrowing, apnoea, cyanosis and cardiorespiratory arrest may ensue within minutes of ingestion. Oxygen gas embolism may produce multiple cerebral infarctions. Although most inhalational exposures cause little more than coughing and transient dyspnoea, inhalation of highly concentrated solutions of hydrogen peroxide can cause severe irritation and inflammation of mucous membranes, with coughing and dyspnoea. Shock, coma and convulsions may ensue and pulmonary oedema may occur up to 24-72 hours post exposure. Severe toxicity has resulted from the use of hydrogen peroxide solutions to irrigate wounds within closed body cavities or under pressure as oxygen gas embolism has resulted. Inflammation, blistering and severe skin damage may follow dermal contact. Ocular exposure to 3% solutions may cause immediate stinging, irritation, lacrimation and blurred vision, but severe injury is unlikely. Exposure to more concentrated hydrogen peroxide solutions (>10%) may result in ulceration or perforation of the cornea. Gut decontamination is not indicated following ingestion, due to the rapid decomposition of hydrogen peroxide by catalase to oxygen and water. If gastric distension is painful, a gastric tube should be passed to release gas. Early aggressive airway management is critical in patients who have ingested concentrated hydrogen peroxide, as respiratory failure and arrest appear to be the proximate cause of death. Endoscopy should be considered if there is persistent vomiting, haematemesis, significant oral burns, severe abdominal pain, dysphagia or stridor. Corticosteroids in high dosage have been recommended if laryngeal and pulmonary oedema supervene, but their value is unproven. Endotracheal intubation, or rarely, tracheostomy may be required for life-threatening laryngeal oedema. Contaminated skin should be washed with copious amounts of water. Skin lesions should be treated as thermal burns; surgery may be required for deep burns. In the case of eye exposure, the affected eye(s) shod eye(s) should be irrigated immediately and thoroughly with water or 0.9% saline for at least 10-15 minutes. Instillation of a local anaesthetic may reduce discomfort and assist more thorough decontamination.

Acupuncture has been used to treat a variety of childhood problems; however, the efficacy and safety of pediatric acupuncture remains unclear. This article reviews the existing empirical literature relating to the use of acupuncture for medical conditions in children. A systematic search of the literature revealed that acupuncture has been used to treat five main conditions in children, including pain, nocturnal enuresis, postoperative nausea/vomiting, laryngospasm/stridor, and neurological disorders. Despite a number of methodological issues, including limited sample sizes, lack of randomization, and inappropriate control groups, it is concluded that acupuncture represents a promising intervention for a variety of pediatric health conditions. To further address the safety, effectiveness, and acceptability of acupuncture in children, large-scale randomized controlled trials are needed.

Tetany is a disorder with a very heterogeneous clinical manifestation. It includes neuromuscular hyperactivity, decreased attention, fatigue, constant anxiety. Attacks of tetany range from mild symptoms, which includes circumoral and distal paresthesias, hyperventilation, accompanied by shortness of breath, palpitation, dizziness, nausea and carpopedal spasm, through more severe symptoms like generalized seizures, loss of consciousness, muscle crumps to life-threatening emergencies like laryngospasm or arrhythmias. Tetany can be a result of many electrolyte disturbances, like hypocalcaemia, hypomagnesemia, hypokalaemia, alkalosis and electrolyte disturbances following hyperventilation. These disorders may occur in many clinical situations including diet deficiencies, alcoholism, endocrine diseases, genetic disorders, iatrogenic causes like proton pump inhibitors therapy and many, many others. It happens that tetany is diagnosed too late and therefore insufficiently cured. For these reason it deserves closer attention.

The number of children with caries requiring general anesthesia to achieve comprehensive dental care and the demand for dentist anesthesiologists to provide ambulatory anesthesia for these patients is increasing. No current published studies examine the safety and outcomes of ambulatory anesthesia performed by dentist anesthesiologists for dental procedures in pediatric patients, and there is no national requirement for reporting outcomes of these procedures. In 2010, the Society for Ambulatory Anesthesia Clinical Outcomes Registry was developed. This Web-based database allows providers of ambulatory anesthesia to track patient demographics and various outcomes of procedures. Our study is a secondary analysis of data collected in the registry over a 4-year period, 2010-2014. Of the 7041 cases reviewed, no cases resulted in serious complications, including death, anaphylaxis, aspiration, cardiovascular adverse events, or neurologic adverse events. Of the 7041 cases reviewed, 196 (3.0%) resulted in a predischarge or postdischarge adverse event. The predischarge adverse event occurring with the highest frequency was laryngospasm, occurring in 35 cases (0.50%). The postdischarge adverse event occurring with the highest frequency was nausea, reported by 99 patients (5.0%). This study provides strong clinical outcomes data to support the safety of office-based anesthesia as performed by dentist anesthesiologists in the treatment of pediatric dental patients.

Background: The Suction Above Cuff Endotracheal Tube (SACETT) has a dorsal port above the cuff designed to enable the continuous or intermittent suctioning of secretions from the subglottic space. Thus, it facilitates the suctioning of excessive secretions above the cuff and around the glottis. Objectives: In this study, we investigated the effect of the using the SACETT on laryngospasm and postoperative complications in rhinoplasty operations. Methods: This randomized controlled clinical trial enrolled 132 patients undergoing rhinoplasty. The patients were randomly divided into two groups: Suction above Cuff Endotracheal Tube (n=66; Group SA) and classic endotracheal tube (n=66; Group C). Complications following general anesthesia were statistically analyzed among the two groups. Results: The incidence of postoperative laryngospasm (p=0.02) and respiratory complications was found to be lower in Group SA than in Group C. In addition, the incidence of agitation (p=0.035), postoperative nausea, and vomiting (PONV) (p=0.041), which required antiemetic drug administration, swallowing difficulty (p=0.012), and sore throat (p=0.027) were found to be lower in Group SA than in Group C. Conclusion: We suggest that using the SACETT in rhinoplasty reduces the incidence of postoperative respiratory complications as well as the incidence of agitation, sore throat, swallowing difficulty, and PONV. Clinical Trial Number: NCT03584503.
