Definition
A surgical day case is a patient who is:
• admitted for investigation or operation on a planned non-
resident basis and
• who non the less requires facilities for recovery.
• The procedure should not require a over night stay in
hospital bed.

• James Hendersin Nicoll, perforned 9000 surgeries b/w
1898-1908
• Ralph Milton Waters
• 1st hospital based ambulatory surgical units were opened
in 1951 and 1952.
• Ambulatory as a recognized subspeciality was enhanced
by formation of SAMBA in 1984 and british association
day surgery in 1989
• Above 2 and 9 other societies now form an ubrella
organization, IAAS (International association for
ambulatory surgery)
Benefits of Day Case Surgery
• Significant reduction in medical costs(d/t overnight
admission, less pre-operative testing and postoperative
medication)
• Increased availability of indoor beds
• Comfort & Convenience of recovering in the familiar home
environment.(particularly in children, it reduces the
separation-induced anxiety problems)
Models of Day Case Surgeries
• Hospital integrated
• Hospital self-contained
• Free standing
• Office based
Patient Selection Criteria
• Surgical factors:
• The extent of surgical trauma- more significant
determinant
• Duration of surgery
• No expectation of significant blood loss, large peri-
operative fluid shifts, or the need for complex or
specialized postoperative care.
• Postop pain
• Conservative minset of some surgeons
Patient Selection Criteria (Cont...)
• Medical Factors:
• Obstructive Sleep Apnea
• Age
• Cardiovascular diseases
Patient Selection Criteria: (Cont...)
• Social factors:
• Access to a telephone/mobile to summon assistance
• Travelling distance
• Discharge with a responsible adult escort and
recommendation to have a to stay with the for next 24 hrs
Preoperative Assessment
• 4 major roles of preoperative assessment:
• Identify absolute contraindications to ambulatory surgery
• Identify need for optimization
• Highlight issues for anesthesiologist or other staffs
• Provide patient information
Pre-operative Assessment (Cont...)
• Mechanisms and timing of preop assessment:
• One stop shop (Preop assessment immediately follows
surgical consultation)
• Basic screening Tool
• Telephonic assessment (with clinic attendance required
only if unexpected problems uncovered or if requested by
the patient)
Pre-operative Assessment (Cont...)
• Preoperative invesgations:
• History and physical examination reamin the key element.
• Routine lab investigation are unhelpful .
• Only selective testing based on pts clinical evaluation and
demographics
• Patient age no longer be advocated as routine preop
testing
Patient Preparation
Provision of information
Preop Fasting
Pre-medication:
• Management of Anxiety
• Anxiolytic premedication
• Analgesic Premedication
• Prophyolactic premedication
• Antacids and gastrokinetic medications
Anestrhesia Techniques
• Choice of technique:
• Appropriate and controllable intraoperative conditions
• Rapid recovery
• Minimal side effects
• Pompt return to normal psychyomotor activity
Anesthesia Techniques
GENERAL ANESTHESIA:
Intravenous Anesthesia:
• Propofol-most practical iv agent for ambulatory surgery
• Why it is ideal choice?
• Rapid and smooth induction without airway irritation and
results in rapid recovery and infrequent PONV
• How the adverse effects can be reduced?
• Pain on injection
• Hypotension
• Induction with Midazolam, Fentanyl, auto-coinduction
Anesthesia Techniques
• Inhaled Anesthetics:
• Most popular choice for maintenace of ambulatory surgery
• Sevoflurane:
• Low-solubility and minimal airway irritation makes it easily
controllable & short acting anestheteic for these surgeries
• Orietation occured earlier than propofol, but time to home
readiness is similar (15 min for both, 25 min faster than with
isoflurane)
• How to reduce the adverse events?
• PONV , Emergence delirium in children
Anesthesia Techniques (Cont...)
• Anesthesia Adjuvants:
• Nitrous Oxide
• Opioid Analgesics
• Non-opioid Analgesia
• Cardiovascular drugs
• Neuromuscular blocking drugs
Anesthesia Techniques (Cont...)
• Airway Management: details to be added
Anesthesia Techniques (Cont...)
• Regional Anesthesia: *details to be added
• Spinal Anesthesia
• Epidural anesthesia
• Intravenous Regional Anesthesia
• Other local or regional anesthesia techniques
Anesthesia Techniques (Cont...)
• Sedation:
• Choice of sedatives:
• Analgesic adjuvants:
• Delivery of sedation:
Monitoring the depth of anesthesia
