Report on 174 cases of tetanus neonatorum collected between 1946 and 1950 in the General Hospital, Singapore. There is a marked reduction in the incidence, which is attributed to a better maternity service. The results of treatment are bad – with a mortality of 90% of cases.
Tetanus may be mild, moderate, severe, or inevitably fatal. Our clinical experience suggests it may be classified as severe (or, maybe, inevitably fatal) when a tetanic spasm stops respiration. Ten patients with severe tetanus were treated by the total paralysis regime (T.P.R.), consisting of tracheostomy, curarization, and intermittent positiveor positive/negative-pressure respiration. Two of the patients were saved by T.P.R. and therefore only limited effectiveness can be claimed for the regime. In inevitably fatal cases survival can be prolonged by T.P.R. so that further effects of tetanus toxin emerge. Of these, the most important appears to be direct damage to the myocardium.
Tetanus, especially tetanus neonatorum (T.N.) continues to be a significant medical and social problem in the developing countries. The case mortality rate remains very high even in the 'developed' countries, varying from 60-80 percent in various reports, and even higher in the case of tetanus neonatorum. Sanders et al had introduced the method of intrathecal injection of antitetanus serum (ATS) in 1976 and have achieved very encouraging results. As the conventional treatment of tetanus neonatorum had achieved very poor result, even in the very sophisticated centres, a case of tetanus neonatorum admitted to Cottage Hospital Semporna in Sabah had been treated with intrathecal ATS since June 1982. This paper reviews the results of this new approach to tetanus neonatorum treatment as compared to cases treated conventionally.
The relationship between the timing of maternal tetanus toxoid immunization and the presence of protective antitoxin in placental cord blood was investigated among women admitted to the obstetrical service of the University Hospital in Kuala Lumpur, Malaysia. The 1st dose was given between 13-39 weeks of gestation, with a median of 29 weeks. The 2nd dose was given an average of 4 weeks later. Protection was conferred on 80% or more of newborns whose mothers received their 1st tetanus toxoid injection 60 days or more before delivery. Protective levels were seen in all cord blood samples from infants whose mothers had received their 1st injection 90 days before delivery. Similarly,protective titers were found in 100% of cord blood samples when the 2nd maternal injection was give 60 days or more before delivery. There was no significant degree of protection when immunization was carried out less than 20 days before delivery. A single-dose schedule provided no protection when less than 70 days before delivery. Cord and maternal antiotoxin titers differed by no more than 1 2-fold dilution for almost all of the individual paired sera. A cord: maternal antitoxin ratio of 2 was more likely to occur with increasing time between the 2nd injection and delivery. Overall, these findings indicate that the 1st injection of a 2-dose maternal tetanus toxoid schedule should be given at least 60 days and preferably 90 days before delivery.
There is a high incidence of tetanus in the Malaysian state of Kelantan. Out of 162 reported cases of tetanus in Peninsular Malaysia during 1979 - 1984, 62 cases were from Kelantan, i.e. 38% of the total reported cases in Peninsular Malaysia. Thus a retrospective study was carried out to analyse the possible factors responsible for this high incidence. 62 cases of tetanus admitted to the General Hospital, Kota Bharu, over a period of 1979 - 1984 were studied.
Neonatal tetanus, though still existing, had been considerably reduced compared to the preceding five-year period (1975-1979). There was notable absence of cases in the two months to four-year age group, 24% of the cases occurred in the 10 - 20 years, and 29% in the age group 25 - 40 years. Since tetanus is a disease preventable by active immunization. l every effort must be taken to improve immunization coverage and increase the public awareness to prevent unnecessary loss of lives.
