Objectives: In Sub Sahara Africa, it is estimated that about 10% of pregnant mothers will develop complications
Maternal mortality; Tanzania; Trained assistant medical officer; C-section; Abnormal labor; Nurse midwife; Anesthesia
About 800 women died of pregnancy or child birth related complications daily mainly in developing countries and most of these deaths are preventable . Tanzania is no exception as the Maternal Mortality Ratio stands high at 460/100,000 live Births versus 3 and 4/100,000 for Singapore and Sweden, respectively. While the Perinatal Mortality ratio is also high (20-39/1,000) compared with 6 and 7/1,000 for German and Japan, respectively [2-4].
WHO estimates that about 1 in 10 pregnant women in Tanzania need emergency maternal health care provided by a skilled medical staff in order to survive in contrast to about 1 in 15 worldwide and the above problems in Tanzania are compounded by the findings of very high physician to patient ratio which is close to 1:25,000 as well as the fact that only 20% of these physicians practice in rural areas where the vast majority of population (>80%) lives [2,3].
In Year 2000, the international community adopted the Fifth Millennium Development Goal (MDG5) in which the community committed itself to reducing the Maternal and Perinatal Mortality by 75% between by 2015. Unfortunately until now only 10% reduction has been achieved [2,3].
Therefore, because of the acute shortage of physicians in especially rural areas, there is an urgent need to train Non Physcian Clinician (NPCs), who were Assistant Medical Officers who were medically educated, they are allowed by Law in Tanzania and in many African countries to do C/S and other surgical operations.
Our objective was to train 1) NPCs namely Assistant Medical Officers (AMOs) on surgical skills and 2) Nurse midwives on anesthesia, so that as team members, they can provide CEMOC at remote, disadvantaged rural areas.
The NPCs were selected mainly from remote disadvantaged Upgraded Health Centers (HCs) in the rural areas of Tanzania. These rural areas had poor transport infrastructure making them almost inaccessible during the long rains.
Two NPCs namely one Assistant Medical Officer (AMO) and one Nurse Midwife were chosen from the each of the HCs. The AMO training included CEMOC and hands-on-training on surgical skills. The surgical procedures they did under supervision included Cesarean Section (C/S), Ruptured uterus, Laparotomy for Ectopic Pregnancy, and abortions and others.
The nurse midwives were trained on administering Spinal and General anesthesia as well as resuscitating babies born with low Apgar score. The duration of training was 12 weeks at ST. Francis Referal Hospital, Ifakara.
During the first 12 weeks from Monday to Friday. The time table was as follows;
1) 7.45 am-9.00 am they presented the emergency cases they had managed under supervision during the previous night.
2) 9.00 am-1.00 pm major ward round in the Maternity wards.
3) 3.00-5.00 pm; Lecture on EMOC topics.
When cases with indications for surgical procedure were found during the ward rounds, the AMOs did the procedures under supervision in the theater.
4) Also a Duty Roster for night duty for the AMOs was made and they attended the patients at night under supervision.
5) Regarding the Nurse Midwives, for 12 weeks under supervision proceeded to administer anesthesia to all patients, be they Obstetrical or general Surgery cases, undergoing surgery from 8.00 am until 3.00 pm. Then had lectures from 3.00 pm to 5 pm and after which they did night duties according to Duty Roster.
They were also taught neonatal resuscitation after C/S in low Apgar score babies.
A total of 36 NPCs from disadvantaged remote Health Facilities were recruited for training and were in two groups (Table 1). The first group of NPCs consisted of 18 AMOs who underwent training on CEMOC which included Obstetrical surgical skills and the second group of NPC consisted of 18 Nurse Midwives who underwent training on Anesthesia.
|Assistant Medical Officers||18|
|Total No. NPCs||36|

There were 1,912 deliveries out which 70% were spontaneous vertex deliveries, 25% C/S, 3% breech and only 2% were vacuum extraction. There were 4 cases of destructive operation due to intrauterine fetal death (Table 2).
|Procedure||Number||% Total Deliveries||Average No.of cases attended by Each NPC|
|Total No. of Live Deliveries||1912|
SVD=Spontaneous Vertex Delivery
AMO=Assistant Medical Officer
Table 2: Mode of Deliveries attended by AMO.
The ruptured uterus cases underwent laparotomies and fresh still births were delivered in 27 cases (Table 3).
|Procedure||Number||Average in each AMO|
|Post Partum Hemorrhage/Retained Placenta||35||2|
AMO=Assistant Medical Officer
Table 3: Obstetric–Haemorrhage-Cases attended by AMO.
The majority postpartum hemorrhage (PPH) cases were mild and due to uterine atony and only 4 required bimanual uterus compression.
There were 5 cases of cervical tear which were sutured in the theatre as well as 6 cases of retained placenta underwent manual removal in the theater.
No maternal death occurred.
1) The Commonest indication for C/S was repeat C/S (22%) the majority of which were due to two or three previous C/S (Table 4).
|Indication for C/S||Number|
|Severe pre eclampsia+eclampsia||54|
|Maternal death post C/S||0|
|Fistula post C/S||0|
Table 4: Cesarean Sections.
2) Obstructed labour (20%) and prolonged labour (18%) came second and third, respectively.
3) Only 2% of the C/S was due to failed induction.
4) 19 patients (4%) had post-operative wound sepsis.
5) No case of maternal death or fistula post C/S occurred.
Anesthesia for patients undergoing C/S and general surgery
Spinal anesthesia was preferred most (45%) followed by bolus ketamine (37%) and general anesthesia with intubation was least (18%).
No case of maternal death due to anesthesia was experienced during the period of training (Table 5).
|Anesthetic Procedure||Number of cases administered (% to Total)||Average cases done by a nurse midwife|
|Spinal anesthesia||348 (45%)||19|
|General anesthesia by Intubation||142 (18%)||8|
|Bolus Ketamine||289 (37%)||16|

The AMOs had good exposure to doing C/S as each of them did an average of 27 C/S under supervision. The C/S rate was 25% and comparable with rates which range from 15% worldwide to 40% in China and Italy [5,6].
During teaching sessions, it was emphasized to AMOs that identifying the correct indication for C/S was crucial and not the procedure itself per se and furthermore, for patients in labour, Partograms were vital in making a decision on whether to proceed to do a C/S or vaginal delivery.
Before starting the training, the AMOs could not fill the Partogram properly as indicated by a Pre-test given, but under supervision they all learnt to fill partograms correctly and consequently detected any abnormality early in labour and intervened before fetal or maternal compromise occurred.
The use of prophylactic antibiotic, early ambulation (12-24 hours) after C/S for even patients who were given spinal anesthesia, and continuous catheter drainage for 7 for obstructed labour patients were emphasized. Consequently the morbidity was low i.e. sepsis rate 4% as well as no fistula, and there was no maternal death.
The NPCs in their rural facilities did not know the use of vacuum extraction machine during assisted vaginal delivery. Therefore, they had to refer to distant district hospitals patients with eclampsia even when they were in second stage with descent of head at station +2, whom otherwise would have easily undergone assisted vaginal delivery by vacuum extraction.
Correct indications and techniques of vacuum extraction during assisted vaginal delivery were reiterated in order to reduce unnecessary C/S.
The low rates of vacuum extraction use in developing countries are associated with the false belief that the procedure is associated with increasing HIV transmission infection rates although there is no documented study on this.
Only 4 patients presented with the right indication for destructive operation. They were all referrals from rural peripheral facilities and they all had obstructed labour with intrauterine fetal death in the second stage of labour with the head at station +2. Usually such patients with intrauterine fetal death undergo C/S at district hospital but the NPCs were shown how to do destructive operation.
Destructive operation are not popular in developing countries and Ahaji et al. , found a rate of 0.5% of all assisted vaginal deliveries despite the fact that a lot of patients presenting with obstructed labour from peripheral rural health facilities have dead fetus and if C/S are done in such patients they are usually associated with severe sepsis which could be fatal [5,6].
The NPCs were also trained to prevent and manage obstetric hemorrhage which is the number one cause of maternal mortality in developing countries  and it was reiterated to them that active management of third stage of labour was crucial.
Before starting the course, they did not know that prophylactic Misoprostol (PGE1) given per rectal in the third stage of labour could prevent PPH. At risk women at the prenatal clinic who were likely to deliver at home were taught by NPC to use per rectal misoprostol after child birth for prevention of PPH.
The importance of Misoprostol in patients with low Bishop Score undergoing induction of labour and also during induction for intrauterine fetal death was realized as shown by the low failure rate (14%) of inductions of labour.
The pre-test on the management of pre-eclampsia and eclampsia revealed that the NPCs were not aware of the use of MgSO4 and instead they stocked Diazepam for eclampsia only and no anticonvulsants was given to cases of severe pre eclampsia.
During the course they learnt the correct use of MgSO4 as exemplified by the low morbidity i.e. no case of stroke or mortality among the severe preeclampsia and eclamptic patients.
The Nurses who underwent training in anesthesia had had no previous exposure to anesthesia and they used to practice only midwifery and other nursing duties at their health facilities.
By the end of the course, they all mastered spinal anesthesia which was commonly used in C/S. The cases requiring general anesthesia with intubation were few (average 8 cases) because of the erratic electricity supply hence risky to intubate and instead administered bolus ketamine as exemplified by an average of 16 patients attended by each nurse.
There was neither mortality nor serious morbidity among cases they attended.
In conclusion, because of the severe shortage of doctors in developed countries and especially in rural areas, this project has shown that training NPCs to do CEMOC is quite feasible and this cadre can work in remote disadvantages health facilities with a view to reducing the maternal and perinatal mortality. Follow up of the NPCs in their facilities to see their impact on maternal and perinatal mortality rates is underway.
