1. Cesarean section is a surgical procedure to deliver fetuses after 28 weeks through an incision in the abdominal and uterine walls. The rate has been steadily rising due to increased safety and availability of blood transfusions and antibiotics.
2. Indications include both maternal and fetal factors like previous cesarean, fetal distress, malpresentation, and maternal conditions like preeclampsia. Timing can be elective or emergency.
3. The standard procedure involves perioperative preparation, a low transverse incision, delivery of the head and body, removal of the placenta, suturing the incision, and postoperative care including fluids, antibiotics, and ambulation.
In this presentation, I have shown how to do open anterior resection both high and low varieties in a step-by-step manner with clear pictures as if reading an atlas of operative surgery.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.

13. a. Perioperative
Premedicative sedative must not be given.
Hair may be clipped.
Informed written permission for the procedure, anesthesia
and blood transfusion is obtained.
Abdomen is scrubbed with soap and nonorganic iodide
lotion.
14. Metoclopramide (10 mg IV) to
increase the tone of the lower esophageal
sphincter as well as to reduce the stomach contents..
Ranitidine (H2 blocker) 150 mg is given orally night before
(elective procedure) and it is repeated (50 mg IM or IV) 1
hour before the surgery
The stomach should be emptied, - stomach tube (emergency
procedure).
Nonparticulate antacid (0.3 molar sodium citrate, 30 ml) is
given orally.
15. IV cannula: sited to administer fluids (ringer’s solution, 5%
dextrose).
FHS should be checked once more at this stage.
Neonatologist should be made available.
Cross match blood
Prophylactic antibiotics should be given (IV) before making
the skin incision.
Bladder should be emptied by a foley catheter which is kept
in place in the perioperative period.

PACKING
-Painted with 7.5% povidone-iodine
solution/ savlon lotion and properly draped
with sterile towels
-Dorsal position. In susceptible cases,
-A 15° tilt to her left using a wedge till
delivery of the baby should be done.
-Vertical or a transverse skin incision.
-Modified pfannenstiel is made 3 cm above
the symphysis pubis.
-The doyen’s retractor is introduced.
-The peritoneal cavity is now packed off
using two taped large swabs.
-The tape ends are attached to artery
forceps. -This will minimize spilling of the
uterine contents into the general peritoneal
cavity
20. b. incision UTERINE

Incision
The most
commonly used
incision (90%) is
low transverse.
21. Other types of uterine incisions
Lower vertical—may be extended upwards when
needed. - Kronig's incision
Classical incision (upper segment).
“J” incision—upward vertical extension of the initial
transverse incision.
Inverted “T” incision—upward extension from the
mid-transverse incision.
Vertical uterine incision - made when the lower
segment is poorly developed or there is complete
anterior placenta previa or any myoma occupying
the lower segment.
22.
23.
24. LOW TRANSVERSE INCISION
Made at a level slightly below the peritoneal incision
until the membranes of the gestation sac are
exposed.
Two index fingers are then inserted and the muscles
of the lower segment are split transversely across
the fibers.
This method minimizes the blood loss but requires
experience.
This is called Munro-Kerr incision
25.
26. c. Delivery Of The Head
The membranes are ruptured
The blood mixed amniotic fluid is sucked
The doyen’s retractor is removed.
The head is delivered by hooking the head with the
fingers
The head is delivered by elevation and flexion using
the palm to act as a fulcrum.
As the head is drawn to the incision line, the
assistant is to apply pressure on the fundus.
Push up the head by sterile gloved fingers
introduced into the vagina.
Delivered using wrigley’s/Baton's forceps.
27. d. Delivery Of The Trunk
Mucus from the mouth, pharynx and nostrils is sucked
out
After the delivery of the shoulders, intravenous Oxytocin
10 units is to be administered.(AMSTL- after delicery of
body)
The rest of the body is delivered slowly
Baby is placed in a tray placed in between the mother’s
thighs with the head tilted down for gravitational
drainage.
The cord is cut in between two clamps and the baby is
handed over to the pediatrician.
The doyen’s retractor is reintroduced.
The optimum interval between uterine incision and
delivery should be less than 90 seconds.
Interval > 90 seconds are associated with poor apgar
28. e. Removal Of The Placenta
And Membranes
placenta is separated spontaneously.
The placenta is extracted by traction on the cord
(controlled cord traction).
The membranes are carefully removed preferably
intact and even a small piece, if attached to the
decidua should be removed using a dry gauze.
Exploration of the uterine cavity is desirable
29. f. Suture Of The Uterine Wound
The suture of the uterine wound is done with the
uterus keeping in the abdomen.
Some, however, prefer to eventrate the uterus prior
to suture.
The margins of the wound are picked up by Allis
tissue forceps or Green Armytage hemostatic clamps
(four are required, one each for angle and one for
each margin).
The uterine incision is sutured in 2 layers.(Three -
controversial)
30. FIRST LAYER:
The first stitch is placed on the far side in the lateral angle of the
uterine incision and is tied.
The suture material is no “1” chromic catgut or vicryl and the
needle is round bodied.
A continuous running suture taking deeper muscles excludingor
including the decidua (very difficult to exclude) ensures effective
apposition of the tissues; the stitch is ultimately tied after the
suture includes the near end of the angle.
SECOND LAYER:
A similar continuous suture is placed taking thesuperficial
muscles and Adjacent fascia overlapping the first layer of suture.
Uterine muscles may be closed using a continuous single layer
stitch taking full thickness muscle and decidua.
There is controversy as regard the place of single layer or double
layer closure in relation to
The risk of subsequent scar rupture. The peritoneal flaps may be
apposed by continuous inverting suture (to prevent any raw
surface).
Nonclosure of visceral and parietal peritoneum is preferred.
31.
32. g. Concluding Part
The mops placed inside are removed and the
number verified.
Peritoneal toileting is done and the blood clots are
removed meticulously.
The tubes and ovaries are examined.
Doyen’s retractor is removed.
After being satisfied that the uterus is well
contracted, the abdomen is closed in layers.
The vagina is cleansed of blood clots and a sterile
vulval pad is placed
34. a. First 24 hours
Day 0
Observation for the first 6–8 hours is important.(Vitals,
hemorrhage)
Fluid:
Sodium chloride (0.9%) or Ringer’s lactate drip is continued until
at least 2.0–2.5 L of the solutions are infused.
Blood transfusion is helpful in anemic mothers and if the blood
loss is more than average during the operation
Oxytocics:
Injection oxytocin 5 units IM - only in case of hemorrhage.
35. Cont.
Prophylactic antibiotics
(cephalosporins, metronidazole) for all cesarean delivery is
given for 2–4 doses.(Cefotaxime)
Analgesics
in the form of Tramadol is administered and may
have to be repeated.
Ambulation:
She is encouraged to move her legs and ankles and to breathe
deeply to minimize leg vein thrombosis and pulmonary
embolism.
The patient can sit on the bed or even get out of bed to
evacuate the bladder.
Baby is
Put to the breast for feeding after 3–4 hours when mother is
stable and relieved of pain.
36. b. Day 1
Oral feeding
Clear fluids may be given.(after 6 to 8 hrs)
Active bowel sounds are observed by the end of the day.
37. c. Day 2
Light solid diet of the patient’s choice is given.
Bowel care:
3–4 teaspoons of lactulose is given at bed time.
38. c. Day 5 or day 6
The abdominal skin stitches are to be removed on the D-7
(in transverse) or D-10 (in longitudinal)
39. d. Discharge
The patient is discharged on the day following
removal of the stitches, if otherwise fit.
Patient may be discharged as early as third to as
late as seventh postoperative days
40. DIFFICULTIES IN CS
1.Floating head:
Gentle fundal pressure helps to bring the fetal head at the site of
incision which is then levered out
2. Deeply engaged head:
Trendelenburg position helps
Patwardhan's technique
Anterior shoulder
Posterior shoulder
Body ( by hooking both axillae assissted by fundal
pressure)
Head
3. Impacted shoulders - Inverted T incision
41. CLASSIC CESAREAN SECTION
Easy to perform
Abdominal incision is always longitudinal (paramedian) and about 15
cm (6") in length, 1/3rd of which extends above the umbilicus.
A longitudinal incision of about 12.5 cm (5") is made on the midlineof
the anterior wall of the uterus starting from below the fundus.
The incision is deepened along its entire length until the membranes
are exposed which are punctured.
In about 40% cases, the placenta is encountered.
In such cases, fingers are slipped between the placenta and the
uterine wall until the membranes are reached.
The baby is delivered commonly as breech extraction.
Intravenous oxytocin 10units im is administered following
delivery of the baby.
The uterus is eventrated.
The placenta is extracted by traction on the cord or removed
manually.
