Anatomical re-evaluation of lumbar dura mater with regard to postspinal headache. Effect of dural puncture.

The effects of puncture of fresh cadaver dura with 20-, 22-, 26- and 29-gauge needles were observed. A 'tin-lid' phenomenon, manifested with all needle sizes, was capable of sealing the resultant hole. The larger the needle, the larger the hole, while rotation of the needle bevel 90 degrees to the fibres altered the shape of the hole. Holes made in thicker parts of the dura tended to retract more rapidly than those in thinner areas.

[Anesthetic data processing--the Bad Säckinger model].

A cost-effective computer program for district hospitals has been developed to process data from anesthetic charts. Apart from monthly and annual statistics relevant to clinical anesthesia and hospital administration, the described system allows free data handling of all material stored in the data base. The possibilities and limitations of electronic data processing are discussed.

Comparison of the effect of continuous positive airway pressure and blowing bottles on functional residual capacity after abdominal surgery.

In two groups of comparable patients undergoing elective abdominal surgery, functional residual capacity (FRC) was measured preoperatively and on the first 2 days after surgery. One group was treated by regular application of continuous positive airway pressure (CPAP), the other group by bottle blowing (BB). In both groups there was a significant reduction of FRC on the first postoperative day. BB and CPAP increased FRC preoperatively by approximately 50%. Postoperative CPAP or BB increased FRC towards the preoperative value. However, 10 min after the treatment was stopped, FRC was not different from the pretreatment level. In 4 healthy subjects the resistive work of breathing produced by CPAP or BB was measured. Both treatments increased mainly expiratory and total resistive work of breathing. BB resulted in especially high expiratory and total resistive work. It is concluded that CPAP and BB increase temporarily the reduced FRC after abdominal surgery. CPAP was much better tolerated by the patients due to the lower resistive work of breathing.

A rationale for epidural analgesia in the treatment of multiple rib fractures.

Thoracic epidural analgesia (EA) is described as an alternative to controlled ventilation in patients presenting with multiple rib fractures. Lung mechanics were especially studied in 6 patients selected from a total of 49. The average ICU stay for this group was 4.5 days (2-11) and the mean age 55.7 years. The EA group was compared with 51 patients primarily ventilated who had an average stay in the ICU of 9.8 days and a mean age of 44.7 years. Mean number of rib fractures of the ventilated group at 6.5 was almost equal to the mean of 6.8 in the EA group. There was a difference in the number of associated fractures, 98 in the ventilated group compared to 35 in the EA group. Severe pulmonary and cerebral contusion were the two most important factors in enforcing the need to ventilate. The success of the method is evidenced by the increase in functional residual capacity (FRC), dynamic lung compliance (Cdyn), vital capacity (VC), the decrease of airway resistance (R) and a significantly increase of PaO2 (p less than 0,001) for the EA group with a balanced fluid therapy. All this accounts for the clinical observation of diminishing paradoxical movement of the flail segment.

The basle PEEP weaner. A versatile device for respiratory assistance.

A device to modify the physiological impact of the abrupt transition of IPPV and PEEP to spontaneous breathing is described. It consists of a coaxial breathing system with a spring-loaded reservoir bag and underwater pressure limit. Electric alarms are incorporated.

Epidural analgesia for the treatment of multiple ribfractures.

Epidural analgesia can be the choice of therapy for all patients with ribfractures and only minor coexisting injuries who are conscious and able to cooperate. In these cases we believe that EA is equivalent or even better than artificial ventilation with all its problems. Generally these patients are far easier to handle and one needs less nursing staff. The dignity of the patients can be maintained and the convalescent time in the intensive care unit is shorter. The criteria for the treatment and for measuring the progress of the patients with multiple ribfractures are discussed.
