2. Objectives
 Principles of drain usage
Drain and its types
Indication/ purpose of drains
Insertion, care and Removal of drain
Complications of drains
Recommendations in surgical practice based on evidence

3. Drain
Tube or deliberate channel- to remove established or potential
collection of pus, blood or body fluid from wound or organ space

4. Principle of drain
Poiseuile law
Laminar flow rate of an incompressible fluid along a tube is
relationship of pressure gradient, radius of tube, viscosity and
length of tube

5. Classification of drain
Basis Types
Rationale Prophylactic Therapeutic
Mechanism Passive Active
Nature Tube Sheet/flat
Disposition Open Close
Location Internal External
Property Inert Irritant

6. Classification of drain
• Rationale
Prophylactic drain placement controversial
Prophylactic Therapeutic
Drain placed at end of
operation to prevent
accumulations
To evacuate an existing
collections
Placed surgically or under
radiological guidance

7. Open drains Closed drains
Drains empty directly to the exterior into
the overlying wound dressing or stoma
bag
Drains externally into sealed container
or reservoir
Increased risk of infection –ascending
along the drain
Lower risk of infection
E.g.: Corrugated drain, Penrose drain,
gauze wick drain, glove finger drain
Easy to care
Accurate assessment of fluid drainage
Penrose drain Corrugated drain Jackson- pratt drain

8. Mechanism: Active drains
• Maintained under negative pressure- High/Low
• Closed ( Jackson-pratt, hemovac drain)
• Open( Sump drain)
Advantage Disadvantage
Keeps wound dry, appose
tissues planes
Causes tissue erosion
Allows fluid drainage
against natural pressure-
pleural space
Prevent fistula closure
Blockage less
Prevent bacterial accession Hemovac drain

9. Mechanism: Passive Drain
• Drains by capillary action, pressure gradient or gravity
• No suction
• Closed ( NG tube, Foley’s catheter, T-tube, Under water seal drain)
• Open( Penrose, corrugated drain, gauge wick drain)

10. Nature of drain
Tube drain Sheet drains
Hollow tubes with multiple holes at one
end
Sheet of gutter or parallel tubes
Corrugated drain, yeates
Abdominal drain Yeates

11. Flat drains
• Flat drain with multiple perforators – connected to tubing system
• Inner wall of flat segment has ribs – prevents from kinking and
collapsing
• Use:- Plastic and reconstructive surgeries

12. Sump drain
• Double lumen, radio opaque
• 1st lumen- suction of gastric
contents
• 2nd lumen- blue extension open to
room air to maintain continuous
flow of atmospheric air into
stomach
• Controls the amount of suction
pressure on tissue/organ and
prevents blockage
• Reduces amount of tissue damage

13. Pigtail drain
• Removes unwanted fluid from organ, duct or abscess
• Inserted under radiological guidance

14. Disposition
External Internal
Open externally outside body wall Placed internally within luminal organs to create a
route or to connect two luminal organs
Fluid channeled from deepest part of cavity to
exterior
Diverts retained fluid from primary drainage site
/area distal to body passage or cavity to bypass
obstruction
E.g.: ventriculo-jugular shunt, ventriculo-atrial shunt,
Dj stents

15. Nature/Drain Materials
Irritant Inert
Rubber or latex Polyurethrane, silicone,
polytetrafluoroethylene
Induces fibrous reaction, allergic rxn Non irritative, no fibrous rxn

16. Indication/ Purpose Of Drains
Therapeutic – remove fluid/pus/gas
• Abscess cavity
• Seroma
• Pleural fluid
• Acute urinary Retention
Palliative- to allow diversion of body fluids/bypass luminal
obstruction
• Advanced Ca oesophagus
• Hydrocephalus
Access route- to body space or cavity
• Percutaneous nephrolithotomy,

17. Diagnostic- injection of dye/contrast about underlying cavity or
fistula to reach diagnosis
• Biliary fistula
• T-tube cholangiogram for retained gall stones in common bile duct
Prophylactic-
 prevents post operative complications arising from fluid collection in wound
cavity
 Promote tissue appostion
Post thyroidectomy
Thoracotomy
Monitoring- of fluid volume and quality
 Gastrointestinal bleeding
 Urinary Catheterisation

18. Drain insertion
Exteriorized via shortest , safest route and through a stab wound not
through the surgical incision
Reach deepest and most dependent part of the cavity or wound
Placed lower than the incision site
Appropriate size and length of drain
Secured at exit to prevent migration of drain-
Silk, safety pin, drain clip, adhesives
Tubing free of kinks, debris, clots—free drainage

19. Securing the drain
A Modified Technique for Securing Drains to the Skin.

Different ways of securing drain

20. Drain Care
• Is the patient well?
• Drain secure?
• Signs of infection, excoriation, peritubal leakage at skin site?
• Tube kinked/ clogged/ damaged?
• Drain connected properly?
• Quality and quantity of drainage fluid?
• Change in nature or volume of effluent?
• Vacuum suction working or not?

21. Drain Removal
• Drain has lived up to its function
• Remove drain with steady gentle traction (avoid sudden jerks)
• Release suction prior to removal

22. Complications and prevention
• Tissue reaction and necrosis
• Hemorrhage
• Source of infection- increase with prolonged drain
placement
• Bowel herniation- if complicated by infection
• Drain entrapment- due to fibrosis
• Fluid and electrolyte loss-high output
• Migration of drain- not secured properly
• Erosion of viscera- in peritoneal cavity without well defined
abscess cavity

23. Evidence based findings
Routine NG drainage after abdominal surgery not recommended
Delay return of gastrointestinal function a/w drain( time to passage of flatus)
NG use –Acute gastric dilation, GOO, Small bowel obstruction, NG feeding
Colorectal surgery-
Drain only if anastomotic leak
Avoid Prophylactic drainage
Appendiectomy
Despite of severity ( gangrenous or perforated or uncomplicated appendicitis)
drain placement a/w increased wound infection and faecal fistula

24. Cholecystectomy
Drain A/w increased wound infection
Avoid in simple cholecystectomy (lap or open)
Hepatic Rection
Subphrenic collection and bilomas m/c complication of liver resection
Drain placement a/w increased risk of infection if collection occurred
Drain failed to detect post operative leakage and hemorrhage
T-tube drainage for CBD exploration following choledocholithotomy
Operative time and postoperative stay longer if t-tube placed

25. Upper gastrointestinal surgery(DU perforation, Gastrectomy)
No difference in incidence intraabdominal collection
Drain a/w increase in complication(10%) and intestinal obstruction(3%)
Pancreatic surgery
Increase (rate of complications and number of interventions for collections)
a/w drain

26. Therapeutic Drainage
Percutaneous drainage under image guidance ( USG or CT) for
symptomatic post operative collection with signs of infection is
recommended for treatment.

27. Take home message
• Drain play important role in management of preoperative, operative
and postoperative patients
• Appropriate drain for appropriate time
• Prophylactic use of drain in various surgeries not recommended
• Therapeutic percutaneous drainage under radiologic guidance for
symptomatic postoperative collections with signs of infection
