This anesthetic protocol is applied to a patient population scheduled for routine procedures and / or urgency; special cases and special surgical procedures require dedicated care procedures. Patients undergoing cardiac surgery, with or without the use of extracorporeal circulation (CEC), as per protocol are rarely extubated in the operating room. Most cardiac patients require breathing support after surgery because of their heart problems; therefore, the use of fentanyl in infants with complex heart defects is not typically problematic. Many children will receive an inhalational anesthetic such as sevoflurane or desflurane, even if induction of anesthesia occurs with an IM or IV agent.

A 4-point scoring system was used to evaluate the child’s behavior at anesthesia induction and mask acceptance 45 minutes after premedication (Table 2). Anesthesia induction was performed using volatile gas, sevoflurane. Heart rate, respiratory rate and peripheral capillary oxygen saturation of each patient were measured and recorded carefully. The cardiovascular effects of three induction agents, thiopentone, methohexitone and Althesin, and four muscle relaxants, tubocurarine, gallamine, pancuronium and alcuronium, were studied in patients about to undergo either open or closed cardiac surgery. The three induction agents lowered the mean arterial blood pressure.

When combined with other medications in the premedication, dexmedetomidine may even provide sufficient analgesia and muscle relaxation for minor surgical procedures to be performed. After proper premedication has been administered it is recommended that brachycephalic patients be “pre­oxygenated” prior to the administration of induction drugs.   In some cases, surgery should be postponed if excessive hypertension or arrhythmia is noted before the induction of anaesthesia. Midazolam premedication decreases preoperative anxiety and stress (2) and postoperative nausea and vomiting (3), potentiates thiopental induction (4) and enhances postoperative analgesia (5).

Premedication and induction of anaesthesia in cardiac surgical patients by Samuel Morrell Lyons Download PDF EPUB FB2

Premedication refers to the administration of medication before the induction of anesthesia. These medications are neither part of the surgical patient’s usual medical regimen nor are they part of the anesthetic. They are given to reduce anxiety, control pain, decrease the risk of aspiration pneumonitis, and lower the incidence of postoperative nausea and vomiting.

Premedication, anesthesia induction, patient risk factors, echocardiography, and patient outcome are clearly emphasized in these chapters. The chapters that follow focus on the management of anesthesia for patients with congenital heart disease and surgical and device therapy for cardiac arrhythmias and cardiac : Carlo Pancaro.

Often, little has been explained to both patient and parents before the day of surgery. Anesthesiologists have a key role in defusing fear of the unknown if they understand a child’s age-related perception of anesthesia and surgery (see Chapter 3.

Anesthesia and Postoperative Care for Cardiac Operations Sait Tarhan, M.D., Roger D. White, M.D., and Emerson A. Moffitt, M.D. ABSTRACT Almost three decades have passed since the establishment of open-heart surgery, and in such a short life span the specialty has established itself scientifically and reached a certain maturity.

Premedication is an important component of the anaesthetic process for patients and is used to smooth the induction of anaesthesia. The amount and type of premedication required varies with patient age, patient wishes, and clinical condition. The practice of anesthetic premedication embarked upon soon after ether and chloroform were introduced as general anesthetics in the middle of the 19 th century.

By applying opioids and anticholinergics before surgery, the surgical patients could achieve a less anxious state, and more importantly, they would acquire a smoother course during the tedious and dangerous induction stage.

Nitrous oxide is seldom used during anesthetic induction in cardiac surgical patients, but it is generally safe to use with the probable exception of patients with markedly increased pulmonary vascular resistance.

Induction of Anesthesia. Cardiac operations usually require general anesthe-sia, endotracheal intubation, and controlled ven-tilation. Some centers have used thoracic epidural anesthesia alone for minimally invasive surgery without CPB or combined thoracic epidural with light general endotracheal anesthesia for other forms of cardiac surgery.

There are no good outcomes data to support restricting fluid intake (of any kind or any amount) more than 2 h before induction of general anesthesia in healthy patients undergoing elective procedures; indeed, there is evidence that nondiabetic patients should be encouraged to drink glucose-containing fluids up to 2 h before induction of anesthesia.

The literature lists these options for premedication or induction of anesthesia in uncooperative patients: Intranasal premedication sedation with either mg/kg of midazolam, or 1 microgram/kg of dexmedetomidine were found to be equally effective in sedating 20 uncooperativechildren aged years for dental treatment visits.

Anesthesia Central is an all-in-one web and mobile solution for treating patients before, during, and after surgery. Most patients would benefit most likely from some degree of myocardial depression induced by the anesthetic agent (with attendant reduction in myocardial oxygen demand); however, patients with very limited myocardial reserve are at risk for congestive heart failure caused by the anesthetic.

Detection and treatment of ischemia are clearly discussed. Consistent throughout the chapters are specific goals for the delivery of anesthesia for a described surgical procedure followed by preoperative cardiac assessment, premedication, preinduction, induction, and maintenance of anesthesia.The mean time interval between oral premedication and induction of anaesthesia was h.

There were no differences between the groups concerning age and duration of surgery. The average age was 51 in the group of treated patients (n = 15) and 59 years in the control group (n = 23).

Premedication with an antihistamine will prevent urticarial reactions in most patients who have a history of allergic reactions. If premedication is not effective or if repeated reactions of increasing severity occur, washed cellular products may be beneficial.
