3. AIM OF POSTOPERATIVE CARE.
To enable a successful and faster recovery of the
patient post operatively.
To reduce post operative mortality rate.
To reduce the length of hospital stay of the patient.
4. POSTOPERATIVE PERIOD.
It is the time period which begins from the time the
patient leaves the operating room and ends with the
follow up visit by the surgeon.
It is divided into three phases;
1. Immediate phase (Post anesthetic phase).
2. Intermediate phase (Hospital stay).
3. Convalescent phase (After discharge to full
recovery).
5. IMMEDIATE PHASE.
It is the time period immediately after shifting the patient
to recovery room from operation theatre till the patient is
fully recovered from anesthesia and shifted to ward.
General Management.
A) Monitoring
Vital sign (pulse, BP, R.R, Temp) every 15-30 min.
C.V.P ( for pulmonary artery wedge pressure) and
arterial line for continuous BP measurement.
ECG
Fluid balance ( intake and output) ? Needs urinary
catheter.
Other types of monitoring :
Arterial pulses after vascular surgery.
Level of consciousness after neurosurgery.
6. B) Respiratory Care:
O2 mask.
Ventilator.
Tracheal suction.
Chest physiotherapy.
C) Position in bed and mobilization:
Turning in bed usually every 30 min. until full
mobilization.
Special position required sometimes.
DVT prevention mechanically ( intermittent calf
compression).
7. D) Diet:
NPO
Liquids.
Soft diet.
Normal or special diet.
E) Administration of I.V. fluids:
Daily requirements.
Losses from G.I.T and U.T.
Losses from stomas and drains.
Insensible losses.
Care of renal patients.
If care of drainage tubes
8. . G) Medication:
Antibiotics.
Pain killers.
Sedatives.
Pre-operative medication.
Care of patients on Pre-Op. Steroids.
H2 Blockers specially in ICU patients.
Anti-Coagulants.
Anti Diabetics.
Anti Hypertensives.
H) Lab. Tests and Imaging:
To detect or exclude Post-Op. complications.
10. THE INTERMEDIATE POST-OPERATIVE PERIOD
Starts with complete recovery from anesthesia and lasts
for the rest of the hospital stay.
General Management.
Care of the wound.
Epithelialisation takes 48 hs.
Dressing can be removed 3-4 days after operation.
Wet dressing should be removed earlier and changed.
Symptoms and signs of infection should be looked for,
which if present compression, removal of few
stitches and daily dressing with swab for C & S.
R.O.S. usually 5-7 days Post-Op.
Tensile strength of wound minimal during first 5 days,
then rapid between 5th - 20th day then slowly again (full
strength takes 1-2 years).
Good nutrition.
11. Case: 1.
40 yr old male K/C COPD underwent paraumbilical
hernioplasty. On 5th POD, a gush of
serosanguinous discharge is noted from wound.
What do you think is a cause of wound dehiscence
in this patient?
A) Poor suture material.
B) Raised intraabdominal pressure secondary to
COPD.
C) Choice of incision.
D) Unavailability of abdominal binder.
12. Wound dehiscence.
It is disruption of any or all the layers in a wound.
Most commonly occurs at 5th to 8th postoperative day.
Most patients require resuturing in OT, some patients
can be left with wound open and treated with daily
dressing or vacuum assisted closure pumps.
Management of drains.
To drain fluids accumulating after surgery, blood or pus.
Open or closed system.
Other types (Suction, sump, under water etc.)
Should come out throw separate incision to minimize
risk of wound infection.
Inspection of contents and its amount.
Should be removed as long as no function or when the
output is <25ml/day.
13. Nausea and Vomiting.
PONV can precipitate bleeding and dehiscence of wound.
Women, nonsmokers and those who have past history of PONV,
migraine and motion sickness are at higher risk.
Duration and type of surgery also affect incidence of PONV, volatile
anaesthetic agents, opiods and nitrous oxide increase risk.
Adequate treatment of pain, anxiety, hypotension and dehydration
minimize the risk of PONV.
Administer antiemetics that work at different sites, such odansetron,
dexamethasone, prochlorperazine, cyclizine, atleast one antiemetic
should be given on regular bases in high risk group and a 2nd one
written up to be given when needed.
14. Bleeding.
All Hospitals should have a major haemorrhage protocol in place.
No need to transfuse blood in the absence of continued bleeding in
patients with Hb > 8g/dl.
If there is continuous bleeding which is more then expected for the
given procedure, then apply pressure to the site and send blood
samples for CBC, CP and cross match.
Start fluid resuscitation.
Arrange U/S or CT scan to assess hematoma.
If haemostasis not successful by conventional method then shift the
patient to OT for reexploration and anastamosis of leaking vessel.
Radiological embolisation of bleeding vessels can also prove useful.
15. Case: 2.
55 yr old obese female underwent APR for rectal
ca. Patient is very reluctant to mobilize despite ur
encouragement & counseling. On 7th POD you
noticed swelling of Left leg with associated
erythema & edema. What you should advice her to
prevent this complication?
A) Compression Stockings.
B) Vena Caval Filter.
C) Low molecular weight heparin.
D) Weight reduction.
16. Deep Vein Thrombosis.
Patient mostly presents with calf pain, swelling, warmth, redness and
engorged veins, but can be asymptomatic.
Venography or duplex doppler ultrasound helps in diagnosis.
High risk patients should be kept on DVT protocol prophylactically,
which includes use of stockings, calf pumps and pharmacological
agents like LMWH.
Treatment involves use of I/V heparin initially followed by long term
warfarin, in patients with large DVT or those who have chance of PE
a caval filter should be placed.
17. Case: 3.
32 yr old male S/p incisional hernioplasty, On 1st
POD staff told you that patient has a spike of 101
fever. You see the patient & found decrease air
entry on right side of chest. What could be cause of
patient's fever?
A) UTI.
B) Wound infection.
C) Atelectasis.
D) inadequate analgesia.
18. Fever.
Common causes of fever according to postoperative day are as
follows,
19. Pressure sores.
Recognize patients at risk.
Address nutritional status.
Keep patients mobile, if bed
bound regularly turn the
patient every 30 minutes or
use an air filter mattress in
high risk group.
20. Post-Operative Pain.
Factors affecting severity :
Duration of surgery.
Degree of Operative trauma (intra-thoracic, intra-abdominal or superficial surgery).
Type of incision.
Magnitude of intra-operative retraction.
Factors related to the patient :
Anxiety.
Fear.
Physical and cultural characteristics.
Complications of Pain:
Causes vasospasm.
Hypertension.
May cause CVA, MI or bleeding.
Management of Post-Op. pain:
Physician – patient communication (reassurance).
Analgesics (NSAIDS).
Anxiolytic agents (Hydroxyzine) potentiates action of opioids and has also an
anti-emetic effects.
Oral analgesics or suppositories e.g. Tylenol.
Parenteral opioids.
Epidural analgesia (for pelvic surgery).
Nerve block (Post-thoracotomy and hernia repair).
21.
22. Post-Operative fluid & Electrolytes
management.
Considerations:
Maintenance requirements.
Extra needs resulting from systemic factors e.g. fever, burn diarrhea and vomiting etc.
Losses from drains and fistulas.
Tissue oedema (3rd space losses)
The daily maintenance requirements in adult for sensible and insensible losses are 1500-
2500mls. depending on age, sex, weight and body surface area.
Rough estimation of need is by body weight x 30/day. e.g. 60 KG x 30 = 1800ml/day.
Requirements is increased with fever, hyperventilation and increased catabolic states.
Estimation of electrolytes daily is only necessary in critical patients.
Potassium should not be added to IV fluid during first 24hs. Post-Op. (because Potassium
enters circulation during this time and causes increased aldosterone activity).
Other electrolytes are corrected according to deficits.
5% dextrose in normal saline or in lactated Ringer’s solution is suitable for most patients.
Usual daily requirements of fluids is between 2000-2500ml/day.
23.
24. Case: 4.
A 55 yr old male S/P exploratory laprotomy & stoma
formation secondary to gut perforation, appears
lethargic on his 4th POD. Physical examination
reveals diminished skin turgor, dry mucous
membranes & rapid tready pulse. His stoma output
is 3500ml in last 24 hrs. Patient is orally allowed on
soft diet. How will you manage the patient?
A) Ask him to drink plenty of water.
B) Replace the deficit via I/V fluids.
C) Start NG feeding of the patient.
D) Reduce ongoing losses.
25. Postoperative Nutritional Support.
For people with mild to moderate illness give;
25-35kcal/kg/day.
0.8-1.5g protein/kg/day.
30-35ml fluid/kg/day.
Adequate electrolytes, minerals, vitamins.
For severely ill patient give;
<50% of the energy and protein levels over the first 24-
48h.
Start at upto 10Kcal/kg/day increasing to full needs over
4-7 days.
Start immediately before and during feeding: oral
thiamine (200-300mg/day), magnesium (0.2-0.4
mmol/kg/day).
26. Case: 5.
48 year old male k/c IHD underwent Exploratory
laprotomy, sigmoid resection and stoma formation
secondary to sigmoid volvulus. 2 hours after the
surgery pt became short of breath, cough up frothy
sputum and start dropping his O2 Saturation. You
gave him a shot of lasix and ordered a CXR which
shows bilateral bat wing appearance. What is the
most likely diagnosis?
A) Pneumonia.
B) Atelectasis.
C) Pulmonary edema.
D) Pulmonary embolism.
27. Post-Operative pulmonary Care .
Functional residual capacity ( FRC) and vital capacity (VC) decrease after major
intra-abdominal surgery down to 40% of the Pre-Op. Level.
They go up slowly to 60-70% by 6th -7th day and to normal Pre-Op. Level after
that.
FRC, VC, and Post-Op. pulmonary oedema (Post anaesthesia) Contribute to the
changes in pulmonary functions Post-Op.
The above changes are accentuated by obesity, heavy smoking or Pre-existing
lung diseases specially in elderly.
Post-Op. atelectasis is enhanced by shallow breathing, pain, obesity and
abdominal distension (restriction of diaphragmatic movements)
Post-Op. physiotherapy especially deep inspiration helps to decrease
atelectasis. Also O2 mask and periodic hyperinflation using spirometer.
Early mobilization helps a lot.
Antibiotics and treatment of heart failure Post-Op. by adequate management of
fluids will help to reduce pulmonary oedema.
28. Case: 6.
36 yr old female underwent elective incisional
hernia repair. You break her NPO after 8 hrs post
surgery and allow sips of water then gradually
proceed to liquids. After 2 hrs of allowing liquids,
patient had 3 episodes of vomiting and developed
abdominal distension. She deny any bowel activity.
What could be cause of patient's condition?
A) Postoperative paralytic illeus.
B) Excessive fluid intake.
C) Lack of mobilization.
D) She developed gastroenteritis.
29. Post-Operative Care of GIT.
NPO until peristalsis returns.
Paralytic ileus usually takes about 24hs.
NGT is necessary after esophageal and gastric surgery.
Gastrostomy and jujenostomy tubes feeding can start on
2nd Post-Op. day because absorption from small bowel is
not affected by laparotomy.
Enteral feeding is better than parenteral feeding.
Gradual return of oral feeding from liquids to normal diet.
30. Case: 7.
22 yr old male pt develop pain in subrapubic region
and unable to void after 6 hrs of elective inguinal
hernioplasty under spinal anesthesia. What should
you order to staff?
A) Give him bolus of 500ml N/S.
B) Catherize the patient.
C) Encourage mobilization.
D) Give him analgesia.
31. Postoperative Renal Care.
Inability to void after surgery is common with pelvic and
perineal operations and procedures performed under spinal
anaesthesia.
Prophylactically catheterize the patient for surgeries expected
to last more than 3 hours or in which large volume of fluid is
administered.
UTI is common in postoperative period, especially in
immunocompromised and diabetic patients, treatment involves
adequate hydration, proper bladder drainage and antibiotics.
Decatheterize patient as soon as possible as it is the biggest
source of infection.
Look for signs of ARI, prophylactic measures to prevent renal
failure in high risk cases, if urine output is less than 0.5ml/kg
for 6 or more hours check for catheter blockage, electrolyte
disturbance, correct hypovlaemia and stop nephrotoxic drugs.
32. CONVALESCENT PHASE
Starts from discharge of patient from hospital till their follow-up
visit.
Discharge card/ letter.
Should have following details;
1. Diagnosis.
2. Treatment.
3. Laboratory results.
4. Complications.
5. Discharge plan.
6. Support needed.
7. Follow-up.
Patient can be discharged from hospital as soon as they can manage their
care.
Follow up.
Follow up can be done in 2 ways;
1. Through telephone.
2. In clinic.
