Classification for coding procedures in the intensive care unit.

BACKGROUND: There is no commonly accepted coding system for non-operative procedures in general, including intensive care unit (ICU) procedures. In order to create a classification of codes for ICU procedures, a system developed at the University Hospital of Bergen was evaluated in four Nordic countries. METHODS: Classification codes were constructed using seven main groups of related procedures that were given a letter from A to G. Within each group major procedures were given a number from 00 to 99, with the possibility of up to 10 subclassifications within each procedure. A simple questionnaire regarding the use of coding general ICU procedures and some specific procedures was sent to 171 ICUs in Sweden, Finland, Denmark, and Norway. They were also asked to give their comments on the new classification coding system, which was attached. RESULTS: One hundred and fifty-four questionnaires were returned (response rate 90%). Some or most of the ICU procedures were registered in the ICUs (82.2%). However 38% did not use any coding system and 24% used a specific internal system. The new classification coding system was well received, and was given a mean value of 7.5 using a VAS scale from 0 to 10 (best). Most ICUs would consider using this system if introduced at a national level. CONCLUSION: Most Nordic ICUs do register some or most of the procedures performed. Such procedures are however, registered in very different ways, using several different systems, and are often home-made. The new classification system of ICU procedures was well rated.

[Emergency dialysis at Haukeland hospital in 1999].

BACKGROUND: The incidence of acute renal failure requiring dialysis is not known in our country. The criteria for acute dialysis are not uniformly accepted, neither is there consensus on dialysis strategy in critically ill patients. We describe the acute dialysis activity in our hospital in 1999. MATERIAL AND METHODS: We have retrospectively recorded the indications for dialysis and the course and hospital mortality in all patients treated with acute dialysis in 1999. RESULTS: 108 patients were treated with 670 dialysis procedures; the incidence was 20.5 per 100,000 inhabitants. Continuous veno-venous haemodiafiltration accounted for 37% of all treatments. In 50% of the patients acute renal failure occurred after surgery or serious infections with a mortality of 57% and 62% respectively. Total dialysis mortality was 45%. The mortality in patients with malignancy and peripheral vascular disease was 90% and 75% respectively. 10% of the patients needed chronic dialysis. INTERPRETATION: The incidence of acute dialysis was higher than previously reported from European countries and may be related to the general increase in active treatment of patients with complicated diseases. The mortality rates are persistently high. Close cooperation between nephrologists and intensivists in the treatment of these patients is essential.

Survival and quality of life 12 years after ICU. A comparison with the general Norwegian population.

OBJECTIVES: To study the long-term (12 year) survival and quality of life (QOL) in former ICU patients. SETTING: Two hundred and thirty-six ICU admissions from a total of 219 patients treated in a Norwegian University Hospital in 1987. DESIGN AND METHODS: A retrospective analysis of the ICU stays and a prospective observation of survival using available information from the Norwegian Peoples Registry. QOL was studied in survivors in 2000 using the Short Form-36 (SF-36) questionnaire. Survival was compared with available statistics for the general Norwegian population (gender- and age-matched), and QOL was compared with published data from a Norwegian reference population. INTERVENTIONS: None. RESULTS: A total of 106 (48.4 %) patients survived the first 12 years after ICU. Of the non-survivors (113) 66.4 % died within the first year. Two years after discharge the further survival of former ICU patients was 0.763 compared to 0.826 in the general population (difference 0.063 with 95 % CI from -0.007 to 0.134). QOL was significantly less than in the reference population in six of the eight scales of SF-36 (average 82.5%). CONCLUSIONS: Our findings indicate that the long-term outcome after ICU is good, with an acceptable QOL and a life expectancy comparable with the general population in survivors 2 years after the ICU stay.

A randomised study of lidocaine and prilocaine for spinal anaesthesia.

BACKGROUND: Transient neurologic symptoms (TNS) are common after lidocaine-induced spinal anaesthesia (SA). Recent data indicate that TNS may be less frequent after prilocaine-induced spinal anaesthesia, for which reason the isobaric solution was compared with lidocaine. METHODS: One hundred patients scheduled for short urologic procedures under spinal anaesthesia were randomised to receive 80 mg prilocaine or lidocaine, both 20 mg/ml. The clinical course and the duration of anaesthesia were monitored. The following day an anaesthesiologist unaware of the randomisation interviewed the patients using a structured questionnaire. RESULTS: Following prilocaine spinal anaesthesia the mean time until 2-segment regression was 123(SD 42) min and total sensory block lasted 221(49) min, compared to 106(26) and 181(48) min following lidocaine. TNS occurred in 7/49 patients in the lidocaine group and in 2/50 in the prilocaine group (ns). CONCLUSION: TNS occurred also after isobaric prilocaine SA. The frequency was not significantly different from that following lidocaine SA but larger studies are needed to establish the relative risk of TNS following SA induced by the two local anaesthetics. Isobaric prilocaine has a longer duration of action than an equal dose of lidocaine and may be an alternative drug for spinal anaesthesia of intermediate or short duration.

Postural post-dural puncture headache. A prospective randomised study and a meta-analysis comparing two different 0.40 mm O.D. (27 g) spinal needles.

BACKGROUND: To compare the incidence of postural post-dural puncture headache (PPDPH) after spinal anaesthesia using two different 0.40 mm O.D. (27 g) spinal needles: pencil-point needle and Quincke needle. In addition, a meta-analysis of studies comparing small bore spinal needles with regard to development of PPDPH was performed. METHODS: Clinical study: A prospective randomised double-blind study was set up to investigate PPDPH after using 0.40 mm pencil-point (Pencan, B. Braun) or Quincke (Spinocan, B. Braun) spinal needle. Postoperatively on day 5 to 7 a telephone interview was conducted in order to reveal postoperative complications such as headache and backache. PPDPH was considered present when the headache was new to the patient, and demonstrated posture dependence. Meta-analysis: Electronic database search and manual search of relevant literature were performed in order to find randomised control trials comparing equal sized (outer diameter, O.D.) spinal needles with different bevel shape. Only studies with a proper method and not merely presented as an abstract were included in addition to the present clinical study. RESULTS: Out of 313 patients randomised, 301 were completely followed up, 153 in the pencil-point group and 148 in the Quincke group. The two groups were comparable regarding surgical procedures and demographic data. Of 15 patients suffering from PPDPH, 12 were found in the Quincke group, and 3 in the pencil-point group. The difference was 6.1% (95% CI from 1.2 to 12.5%). The meta-analysis of 1131 patients gave a relative risk of developing PPDPH of 0.38 (95% CI from 0.19 to 0.75) in the pencil-point group compared to the Quincke group. CONCLUSION: A pencil-point-shaped spinal needle will significantly reduce PPDPH compared with Quincke-type spinal needles, also when small bore needles (0.40 mm O.D.) are used.

Effect of experience with spinal anaesthesia on the development of post-dural puncture complications.

BACKGROUND: This clinical study was conducted in order to investigate the effect of operator experience with spinal anaesthesia (SA) on development of postural post-dural puncture headache (PPDPH) and postoperative backache. METHODS: The study was a cohort study of the first 100 SA performed by each of 5 trainees in anaesthesiology at the very beginning of their training period. SA was conducted with assistance and guidance according to usual departmental practice. In each SA, data regarding level of puncture, needle size, number of punctures, use of introducer and infiltration anaesthesia were recorded. In addition, usual problems and complications connected with dural puncture were registered. A visual analogue scale was used to record how difficult the procedure was experienced by the trainees. Postoperatively, the patients were contacted by the same trainee, usually by telephone. A semi-structured interview was conducted where occurrence and duration of headache, backache and other complaints were recorded. Headache was classified as PPDPH or non-PPDPH, and intensity of the headache was registered using a numerical rating scale (NRS) from 0 to 10. RESULTS: Five hundred SA in 495 patients with a mean age of 61.3 years were included in the study. Of these, 394 patients were completely followed-up postoperatively; the main reason for the drop-out was patient-related factors such as advanced age and dementia. Headache occurred in 56 patients postoperatively. PPDPH was diagnosed in 33 and non-PPDPH occurred in 23 patients. Postoperative backache was experienced by 27 patients. No significant effect experience with SA could be found regarding the occurrence of postoperative complications; 16 compared to 17 patients with PPDPH were found in the first and the last half of patients. A marked inter-individual difference in the occurrence of PPDPH was found in the patients treated by the 5 trainees. CONCLUSIONS: We could not demonstrate an effect of experience and training on development of complications after SA with regard to PPDPH and backache.

Errors in the intensive care unit (ICU). Experiences with an anonymous registration.

BACKGROUND: In order to obtain information about the occurrence and severity of errors in an ICU, this investigation was conducted in a combined ICU and postoperative ward at a Norwegian University Hospital. METHODS: An anonymous registration was conducted in order to reveal as many as possible of all errors in the unit. A separate registration form was used, recording the type of error, date and time, sex and age of the patient, patient condition (unstable/stable) and where the error occurred (on the ward or during transport). The registration started in October 1995, and reports until November 1996 are included (13 months). Consequences of the errors were graded using a 6-point scale (0=no consequences and 5=fatal). Two experienced intensivists and two experienced ICU nurses independently evaluated the errors using a visual analogue scale (VAS) with 10 as the worst imaginable error. All four were blinded to consequences of the error. RESULTS: A total of 87 errors was reported: 36 (41.3%) were medication errors, 17 (19.5%) related to intravenous infusions, 15 (17.2%) were due to technical equipment failure, and the rest (19 errors, 21.8%) miscellaneous. No consequences could be detected in 55 cases (63%) (grade 0). Six errors were graded as 1, and 22 (25%) as grade 2 (therapeutic intervention necessary, no damage recorded). Five errors had more serious consequences, and one was fatal. The scoring of errors varied a great deal. Mean VAS score was 4.2 (SD 1.7). The sum of VAS score (max. 40) on each error followed a normal distribution, and 12 errors had a score >25. CONCLUSION: Errors happen frequently in the ICU. Probably, our data do not represent the true incidence of errors in the period, which we believe was higher. Many errors are graded as serious or severe, but still have limited consequences for the patient.

Improved oxygenation using the prone position in patients with ARDS.

BACKGROUND: The prone position is known to increase oxygen uptake in patients with Adult Respiratory Distress Syndrome (ARDS). METHODS: In this clinical study from 1995-96, 14 ARDS patients with severe respiratory failure were treated for at least 1 h in the prone position. Responders, defined as having more than 10% increase in PaO2/FiO2 ratio from baseline after 1 h, were treated at least 6 h in the prone position. RESULTS: 11 patients responded during the first period of the prone position (primary responders). Two of the 3 non-responders were turned prone a second time with increase in the PaO2/FiO2 ratio (secondary responders). Mean PaO2/FiO2 ratio (mean +/- SEM) in the supine position was 11.7 +/- 0.8 kPa, increasing to 16.6 +/- 1.8 kPa and 18.0 +/- 1.4 kPa after 1 and 6 h respectively (P = 0.009). Mean time spent in the prone position was 69 h (range 3-256 h), and mean ventilatory time was 17 d (3-52 d). The mortality in this subgroup of our patients with ARDS was 42%, compared to 58% in 19 patients not turned prone in the same period. CONCLUSION: The prone position together with PEEP appears to improve ventilation-perfusion matching. The prone position is simple, effective and readily available and could be used early in most patients with ARDS.

Puncture technique and postural postdural puncture headache. A randomised, double-blind study comparing transverse and parallel puncture.

BACKGROUND: This clinical study was conducted in order to investigate the effect of two different orientations of the bevel during dural puncture on development of postural postdural puncture headache (PPDPH). METHODS: Two hundred and eighteen patients aged 18 to 50 years scheduled for minor non-obstetric surgery using spinal anaesthesia (SA) were included in this randomised, double-blind study. Dural puncture was performed using a 0.42 mm O.D. (27-g) Quincke spinal needle with the orientation of the bevel parallel or transverse relative to the longitudinal axis of the dural cylinder. All patients were blinded with regard to the puncture technique, and so was the anaesthesiologist performing a telephone interview 5 to 7 days postoperatively. The occurrence and duration of headache, backache and other complaints were recorded. Headache was classified as PPDPH or non-PPDPH, and intensity of the headache was registered using a numerical rating scale (NRS) from 0 to 10. RESULTS: Two hundred and twelve patients with a mean age of 35.3 years completed the study, 106 in each group. The two groups were comparable with regard to mean age, sex, local anaesthetics used and surgical procedure performed. Headache occurred in 44 patients postoperatively. PPDPH was diagnosed in 4/106 patients (3.8%) in the parallel group and 24/106 (22.6%) in the transverse group (P < 0.0002). Postoperative backache occurred in 31 and 20 patients (parallel compared to transverse) (NS). CONCLUSIONS: Dural puncture with the bevel of the needle transverse to the longitudinal axis of the dural cylinder gave significantly more cases of PPDPH than puncture with the bevel parallel to this axis even when using a 27-g Quincke needle. When using Quincke bevelled needles care must be taken to assure that the orientation of the bevel is parallel to the longitudinal axis of the dural sac.

Postural post-dural puncture headache after spinal and epidural anaesthesia. A randomised, double-blind study.

BACKGROUND: This study was conducted in order to investigate the effect of patient expectation in the development of postural post-dural puncture headache (PPDPH). METHODS: 224 patients less than 55 years scheduled for minor non-obstetric surgery were randomised to receive single-injection spinal (SA) or epidural (EA) anaesthesia. A 27-g Quinke needle was used for SA and a 18-g Tuohy needle for EA. Patients, operating team and postoperative ward personnel were all blinded to the anaesthetic given and so was an independent observer responsible for follow-up after 5-7 days. The occurrence of headache, backache and other complaints was recorded. Headache was classified as PPDPH or non-PPDPH, and duration and intensity of the headache was registered. The quality of anaesthesia was directly evaluated by the surgeon using a VAS scale from 1 (excellent) to 10 (very poor) and indirectly by the supplemental use of opioid analgesia and general anaesthesia in the two groups. RESULTS: 212 patients, 103 SA and 109 EA, with a mean age of 36.7 years, could be fully evaluated. The groups were comparable with regards to age, sex and surgical procedure performed. Headache occurred in 44 patients postoperatively. PPDPH was diagnosed in 16 patients (15.5%) in the SA group and 2 (1.8%) in the EA group (P = 0.0014). Non-PPDPH occurred in 13 patients in each group. PPDPH had significantly greater mean intensity and duration than non-PPHPH. More patients in the EA group had postoperative backache (31.2%) than in the SA group (22.3%), but this difference was not statistically significant. More patients in the EA received general anaesthesia and opioid analgesia than in the SA group, and the surgeon's rating was on average 1.3 in the SA group compared to 2.5 in the EA group (P = 0.0003). CONCLUSIONS: SA gave more headache but superior quality of surgical anaesthesia compared with EA. Dural puncture, and not expectation, is the major cause of PPDPH.

Post-dural puncture related complications after diagnostic lumbar puncture, myelography and spinal anaesthesia.

OBJECTIVES: This study was conducted to investigate complications after dural puncture. MATERIAL AND METHODS: A 15 months' prospective observation study of routine clinical practice with dural puncture at a university hospital was conducted. Quincke spinal needles 0.90 to 1.0 mm O.D. (20-19 g) were used for diagnostic lumbar puncture, 0.70 mm O.D. (22 g) for myelography and 0.40 to 0.50 mm O.D. (27-25 g) for spinal anaesthesia. A questionnaire about post-puncture discomfort was given to the patients, to be returned after 1 week. RESULTS: Of 679 questionnaires 537 (79.1%) were returned. Discomfort was experienced by 53.8% of the patients, most often after diagnostic lumbar puncture and myelography. The difference in incidence of headache after diagnostic lumbar puncture and myelography compared with spinal anaesthesia were 27.9% (95% CI: 18.6 to 37.2) and 18.3% (95% CI: 9.1 to 27.5). CONCLUSION: Small diameter and atraumatic spinal needles will reduce patients' discomfort after dural puncture.

[Intensive care in Norway. A questionnaire study].

A questionnaire was sent to five university hospitals, 16 central hospitals and eight large local hospitals. They were asked about the number of beds and the physicians employed in the intensive care unit (ICU), the use of some important intensive care procedures and treatments, registration and documentation procedures, and activity data for 1995. All the hospitals answered the questionnaire. The size of the unit varied from 5.5 to 7.0 beds and use of physicians varied from 1.3 to 5.2 (local vs university hospitals). Only six of the units use APACHE or SAPS severity scoring systems, and only three register work-load objectively. Definition of time spent in the ICU or on a ventilator varies. It is impossible at present to make a meaningful comparison of activity at the different intensive care units in Norway. If the situation is to be improved it is necessary to take the initiative for uniform use of definitions, objective scoring systems and registration of work-load. Such an initiative should come from the hospitals and the Norwegian Medical Association, in collaboration with the central health authorities.

[Nasoenteral tube feeding in hyperemesis gravidarum. An alternative to parenteral nutrition].

A severe form of hyperemesis gravidarum involving maternal weight loss greater than 5% of the prepregnant weight occurs in up to 0.1-0.2% of all pregnancies and may lead to retarded foetal growth. Treatment consists of hospitalisation, antiemetics and correction of fluid and electrolyte deficiencies. If severe vomiting and weight loss continues, the mother must receive supplementary nutrition, usually parenteral. Nasoenteral tube feeding is a well documented method of nutrition for other patients. A gastroscopically placed nasojejunal tube as part of the treatment of hyperemesis gravidarum has not been reviewed before. Seven women with severe hyperemesis gravidarum were treated with nasojejunal tube feeding. The tube was positioned gastroscopically. Enteral feeding continued for up to 41 days, leading to reasonable weight gain. The tube was tolerated well by most patients and no serious adverse effects were seen. Nasoenteral nutrition ought to be considered as an alternative to parenteral nutrition for treatment of hyperemesis gravidarum.
