ANESTHESIA FOR DAY CARE SURGERY Presented : Dr. Nitin Bhalla, P.G. Student, Department of Anesthesiology and Critical care, Dr. S.N. Medical College, Jodhpur. 1
Introduction to Ambulatory Surgery
Ambulatory anesthesia is administered with the dual goals of rapidly and safely establishing satisfactory condition for the performance of therapeutic or diagnostic procedures while ensuring rapid, predictable recovery with minimal post operative sequelae.
Benefits of “Day Care” or “Ambulatory” Surgery
Patient preference, esp. children and the elderly
Lack of dependence on the availability of hospital beds Greater flexibility in scheduling operations
Low morbidity and mortality
Lower incidence of infection Lower incidence of respiratory complications
Higher volume of patients
Shorter surgical waiting lists Lower overall procedural costs
Less preoperative testing and postoperative medications
Patient selection criteria for ambulatory anaesthesia
ASA physical status ASA status I, II and medically stable ASA status III The risk of complication can be reduced if pre-existing medical conditions are under good control for at least 3 months before operation.
Age Premature infants < 46 weeks of postconceptional age are at increased risk and are not an ideal candidate for Ambulatory surgery. Anemia is a sinificant independent risk factor , particularly for infants less than 43 weeks of post conceptional age. Elderly outpatients may experience a higher incidence of perioperative CVS event and slow recovery of fine motor skills and cognitive functions.
Patient selection criteria for ambulatory anaesthesia
Social Factors 1.The patient must be prepared to have the procedure performed as a day case, 2. live close to the hospital, and 3. Should have a responsible, able, adult carer at home with them for 24 hours postoperatively Surgical procedure - Ideally, surgical procedures for the ambulatory patient should be completed in a reasonable amount of time, should not require blood transfusion and should not create excessive fluid shifts. Duration of Surgery – in the ambulatory setting should be less than 90 minutes.
Medical contraindications for day case anesthesia Morbid obesity • Body mass index > 35 kg/m2 or weight > 125 kg Cardiovascular disease • Poorly controlled angina, arrhythmia or cardiac failure • Hypertension > 180/100 mm Hg • Significant valvular or congenital heart disease • Myocardial infarction or stroke within 6 months Respiratory disease/airway • Poorly controlled asthma or chronic obstructive pulmonary disease (patients taking oral corticosteroids, with poor exercise tolerance or with a peak expiratory flow rate < 200 litres/minute are unlikely to be suitable) 1 • Severe restrictive lung disease (e.g. kyphoscoliosis) • Previous failed intubation • Significant obstructive sleep apnoea Continued...
Medical contraindications for day case anesthesia (contd.) Metabolic/endocrine/haematological • Poorly controlled diabetes or insulin dependent 1 • Active liver disease • Anaemia (haemoglobin < 10 g/dl) 1 • Haemophilia/anticoag Haemophilia/anticoagulation ulation 1 • Cholinesterase deficiency 1 • Hypo- or hyperkalaemia (acceptable range 3–6 mmol/litre) Renal disease • Patients requiring renal support 1 Neuromuscular Neuromuscular disease • Myasthenia gravis • Significant multiple sclerosis • Malignant hyperpyrexia susceptibility • Poorly controlled epilepsy • Parkinson’s disease interfering with daily activity • Significant motor neuron disease Acute substance abuse

Pre – Operative Preparation
Aims of Pre – Operative Preparation
Aims – Reducing the risk inherited in Ambulatory Surgery. Improving patient outcome. Making the surgical experience more pleasant to the patient. Minimizing patient anxiety. Reduce potential post operative problems.
Non Pharmacological Methods Non – Pharmacological techniques should be aimed to allay anxiety and fear of the patient regarding the operative procedure. Patient should also be instructed (written and verbal) regarding the arrival time and place, fasting instructions and information concerning the post operative course, limitation in driving skills, and the need for a responsible adult to care for the patient during post operative period. Benefits of Non Pharmacological methods – Economical Lacks undesirable side effects. High patient acceptance and motivation.
Non-Pharmacological Non-Pharmacological methods – Patient Interview. Instructional Instructional preoperative video tapes. Music before surgery Self hypnotic relaxation techniques. Play oriented pre-operative teaching, Books, pamphlets, and video programs – specifically in pediatric patients.
Pharmacological methods
Anxiolysis and Sedatives
Benzodiazepines – Midazolam - drug of choice. (I.M., I.V., PO)
α 2
Oral Temazepam and alprazolam adrenergic agonists –
Clonidine - residual post operative sedation is concerned factor. Dexmedetomidine - Shorter duration of action and highly selective α 2 agonist.
Pharmacological methods (contd..)
Analgesics –
Opioid Analgesics – Relive anxiety, Decreases anesthetic doses, minimize hemodynamic response, provide post operative pain relief. Shorter acting – Fentanyl, alfentanil, Remifentanil, Sufentanil
NSAID’s – As mutiimodal analgesic technique, in combination, it facilitates early recovery and reduces discharge time. For maximal benefit in ambulatory surgery, NSAID’s s/b administered on “fixed” dosage shedule. More selective COX – 2 inhibitors s/b used. Oral – Rofecoxib, Celecoxib, Valdecoxib Parentral - Parecoxib
Pharmacological methods (contd..)
Prevention of Nausea and Vomiting As a mutimodal regimen , combination of anti-emitic drugs are used to prevent PONV
.
Droperidol – Low dose ( < 10mcg/kg) Metoclopramide – 20 mg iv / 0.2 mg/kg iv Dimenhydrinate and Hydoxyzine – 0.5 mg/kg. Ondansetron, granisetron, dolasetron, tropisetron Neurokinin – 1 antagonists Dexamethasone – 4 to 8 mg iv Acupuncture and acupressure.
Pharmacological methods (contd..)
Prevention of Aspiration Pneumonitis H2 receptor antagonists – Ranitidine – 150 mg p.o. ; 50 mg iv Pantoprazole – 40 mg iv Antacids – Sodium Citrate 15-30 ml po. Prokinetic - Metoclopramide – 10-20 mg iv NPO

Opioid Analgesics –
Fentanyl – 1-2 mcg/kg Alfentanil – 15-30 mcg/kg Sufentanil – 0.15-0.3 mcg/kg Remifentanil – 0.5-1 mcg/kg
General Anesthesia (contd...)
Sufentanil with N2O has lower incidence of nausea and P.O. pain as compared with fentanyl with N 2O.
Emergence and recovery of psychomotor functions are faster with alfentanil as compared to Fentanyl. Also Afentanil is associated with lower incidence of PONV as compared to Fentanyl or Sufentanil. Remifentnil is an ultra-short acting opioid with a half life of 810 minutes and a context sensitive half life of 4 minutes regardless of duration of infusion.
In elderly patients, TIVA with remifentanil and propofol is associated with more rapid recovery than a standard Fentanyl-Isoflurane technique.
General Anesthesia (contd...) Inhaled Volatile anesthetic agents –
Most commonly used for the maintance of anesthesia. Fast patient recovery and earlier discharge. Volatile anesthetic agents that can be used for ambulatory anestheisa are – Sevoflurane, Desflurane and Isoflurane. Sevoflurane – induction of anesthesia in adults as well as in pediatric patients. Desflurane – Emergence faster than other inhalation agents; Rapid recovery of cognitive and psychomotor function; Better postural control than after propofol. Associated with higher incidence of vomiting in early p.o. period Use of N2O as an adjuvant is beneficial.

Modes of Regional Anesthesia –
Epidural and spinal techniques
Intravenous regional anesthesia
Peripheral Nerve Blocks
Local Infiltration techniques
Regional Anesthesia Advantages to patients : (a) Improved quality of recovery i. Less pain (mainly with CPNB) ii. Less PONV iii. Less unplanned hospital admission (b) Able to observe the procedure (c) Communication with surgeon during the procedure, (d) Option to receive no or light sedation. (e) Earlier mobilization. Advantages to surgeon and Hospital : (a) Fast tracking of recovery, (b) Less requirement of post op. surgery staff, (c) Less requirement of drugs, so chance of adverse reaction is less, (d) Economical.
Regional Anesthesia (contd..)
Disadvantages of RA in ambulatory surgery: (a) (b) (c)
Takes time and new separate setup to be organized, Patients active co-operation is needed Risk of complications : Nerve damage, TNS after Spinal anaesthesia. (d) Variable failure rate (up to 10% with PNB) (e) Urinary retention with Spinal Anaesthesia.
Regional Anesthesia (contd..)
Spinal Anesthesia – Although simple and most most reliable reliable reg. anesthetic tech., is associated associated with higher incidence of side effects. For Ambulatory Anesthesia , short acting local anesthetics (Lidocaine and procaine) is preferred over the bupivacaine and tetracaine. Recommendations Recommendations – Isobaric lidocaine, or combination of small dose of hypobaric lidocaine lidocaine (1% ; 20-25mg) 20-25mg) combined with with fentanyl (10-25mcg) (10-25mcg) or sufentanil. For ambulatory surgeries lasting for > 2 hours, Intrathecal bupivacaine can be used. Associated with – delayed ambulation, dizziness, urinary retention, and impaired balance. Epidural Anesthesia Anesthesia - is technically more difficult difficult to perform, slower onset of action, potential for intravascular / intrathecal injection, greater chances of incomplete sensory block.

Monitored Anesthesia Care
MAC is the term used when an anesthesiologist monitors a patient receiving local anesthesia or administers supplemental drugs to patient undergoing diagnostic or therapeutic procedures.
ASA defines MAC – instances in which an anesthesiologist has been requested to provide specific anesthesia services to a particular patient receiving local anesthesia or, in some cases, no anesthesia al all.
Goal of MAC – providing analgesia, sedation, and anxiolysis and ensuring rapid recovery without side effects.
Vigilant monitoring is required as patient may progress from ‘Light’ level of sedation to ‘ deep’ sedation or unconciousness.
Monitored Anesthesia Care (contd..)
Small dose of midazolam (1-2mg) or propofol (0.5-1mg/kg) or both, followed by a propofol infusion at 25-100mcg/kg/min. Methohexital – 10-20mg bolus ; or variable rate infusion (13mg/min.) Alfentanil (0.3-0.4mcg/kg/min) + propofol (25-75 mcg/kg/min.) infusion – “Avramov and White”. Remifentanil infusion (0.05-0.15 mcg/kg/min). Ketorolac – sole or as an adjuvant to propofol. Low dose ketamine (0.25-0.5 mg/kg) with w ith midazolam or propofol. Subanesthetic conc. Of inhaled anesthetics – (N 2O -30% to 50%; Sevoflurane 0.3% to 0.6%) α 2
agonists – clonidine or Dexmedetomidine
Concept of “Fast – Tracking” Bypassing the PACU has been termed “Fast-Tracking” after ambulatory surgery.
Criteria used to determine fast-track eligibility eligibili ty after ambulatory anesthesia

Assessment of Recovery Discharge Criteria
Assessment of Recovery
Recovery includes return of normal physiological physiological and psychomotor psychomotor functions with a minimal level of morbidity associated with anaesthesia and surgery. Recovery is a continuous continuous process, the beginning of which overlaps with the end of the surgical procedure. Patients are not fully recovered until they have returned to their preoperative physiological and psychomotor state. The process may last for days, but it can be divided into distinct phases.
Stages of Recovery
Stage of Recovery Clinical definition 1. Early recovery : Awakening and Recovery of vital reflexes 2. Intermediate Intermediate recovery :Intermedia : Intermediate te clinical recovery, recovery, home readiness readiness 3. Late recovery : Full recovery, psychological psychological recovery
Phases / Stages of Recovery
Phase I / Early recovery –
Phase II / Intermediate recovery –
It is the time interval during which patients emerge from anesthesia, recover control of protective reflexes, and resumes early motor activity. During this phase of recovery, patients are cared for in the PACU. The Steward and Modified Aldrete score is commonly used to assess the fitness of patient to be transferred to the Phase II recovery area. During this period , patients are usally cared for in a reclining chair and progressively begin to ambulate, drink fluids, void, and prepare for discharge. For second-stage recovery the Excitement Score or the Post-anaesthesia Discharge Scoring System (PADS) is used
Phase III / late recovery –
This period begins when the patient is discharged home and continues until functional recovery is achieved and the patient is able to t o resume normal activities of daily living.

Discharge criteria after Regional anesthesia
Besides the recovery criteria for general anesthesia, patients with regional anesthesia must fulfill additional criteria. These are –
Normal perianal sensation (S4-S5 )
Able to plantar flex the foot
Proprioception of the big toe.
Normal Blood pressure on standing and sitting.
Causes of prolonged recovery following regional and general anaesthesia
• Pain • Nausea and vomiting • Haemorrhage • Cardiovascular or pulmonary dysfunction • Wound drains • Needing observation • Lack of escort or inadequate home conditions
Post operative instructions Both written and verbal instructions should be given regarding the post operative period before discharging the patient In general, for 24 hours after anesthesia: 1.Do not drink alcohol or use nonprescription medications. 2.Do not drive a car or operate dangerous machinery. 3.Do not make important decisions. The patient should be provided with a contact number to contact in case of any emergency.
Application of Ambulatory anesthesia in specific population
Pediatric patients
Sedative premedication premedication is generally not offered in children younger than 12 months.
Oral or rectal premedicant remains the choice in pediatric patients.
Midazolam is the most commonly used anxiolytic premedicant for pediatric patients. patients. ( dose – 0.5 mg/kg po)
Ketamine , provides hyponsis without cardiorespiratory depression, and can be given per rectally or i.m.
Geriatric Patients
Perioperative functional status status can be difficult to quantitate because many elderly patients have reduced preoperative function related to de-conditioning, age – associated disease dise ase or cognitive impairment.
Geriatric patients tend to have decreased beta-adrenergic responsiveness and they experience an increased incidence of conduction abnormalities, bradyarrhythmias and hypertension.
Hypovolemia or overperfusion are both poorly tolerated.
The elderly have a two-third reduction in anaesthetic requirement because of fundamental neurophysiologic changes in the brain.
Cardiovascular Disease patients
Patients with well-controlled cardiovascular disease should not be denied the opportunity to have their surgery s urgery in the ambulatory setting.
However, patients with poorly controlled angina, congestive cardiac failure, symptomatic valvular disease, uncontrolled arrhythmias or recent myocardial infarction or stroke (within 6 months) are unsuitable for elective surgery.
Hypertension is associated with an increased risk of developing perioperative cardiac events and should be treated before surgery. A reasonable upper limit for blood pressure is 180/100 mm Hg.
Diabetic patient
Diabetes is a predictor of adverse intraoperative and postoperative events, but patients with good diabetic control and a good understanding of their disease should be allowed day surgery. Patients with Type 2 diabetes are, in general, more suitable for day surgery than those with Type 1 diabetes. A complication of unique concern for anaesthesiologist is the diabetic “stiff joint syndrome”. Glycosylation of collagen decreases mobility of the cervical spine and TMJ and may increase the likelihood of difficult laryngoscopy and intubation. Stiffness of the 4th and 5th interphalangeal joints (prayer sign) assessed using palm prints is a sensitive predictor of difficult intubation. It is recommended that patients receive insulin long with a continuous infusion of dextrose on arrival arr ival to the ambulatory unit.
Morbid Obesity
Obesity is often associated with cardiac disease, diminished respiratory reserve and gastro-oesophageal reflux.
Body mass index greater than 35 kg/m2 is associated with perioperative anaesthetic and surgical problems, and is often used as a cut-off point for patient suitability.
Desaturation and bronchospasm are frequently noted complications.
Patient with Asthma or COPD
Asthma, chronic obstructive pulmonary disease and smoking all predict adverse perioperative events, but patients with wellcontrolled disease are likely to be suitable for day surgery.
A regional anaesthetic technique can be considered for the more seriously affected.
Patients with poorly controlled disease, marked exercise limitation or a recent exacerbation of their condition should have their surgery postponed. Smokers should be encouraged to stop smoking.
Obstructive Sleep Apnoea
Out-patient surgery for OSA patients remains controversial even in developed countries. OSA patients are more likely to be difficult to intubate ; Several factors, including obesity, retrognathia and increased neck circumference contribute to the increased difficulty with intubation. The severity of OSA is determined by the apnoea-hypopnoea index which is the number of apnoeas or hypopnoeas per hour of sleep. (mild 5 – 15, moderate 15 – 30, severe > 30) Recovery room complications are also more frequent and may include hypertension, dysarrhythmias, desaturation, airway obstruction or reintubation. well-treated OSA patients having low risk procedure performed under local anaesthesia or regional anaesthesia with little or no sedation and minimal need for narcotic-based analgesia can be discharged after surgery. Pain should be managed with non-narcotic analgesics and opioid drugs should be avoided.
