Comparison of prevalence of post-dural puncture headache between six hour- supine recumbence and early ambulation after lumbar puncture in thai patients: A randomized controlled study.

OBJECTIVE: To compare the prevalence of Post Dural Puncture Headache (PDPH) between 6 hour- supine recumbence and early ambulation in Thai patients. MATERIAL AND METHOD: The present study was a prospective controlled study and enrolled the patients who underwent Lumbar Puncture (LP) from Phramongkutklao Hospital, Thailand. The background characteristics were recorded Standard LP method was done. The patients were randomized to 6 hour-supine recumbence and < or = 1 hour- (early ambulation) groups. Prevalence and characteristics of PDPH were compared. RESULTS: Of 65 patients, there were 33 patients (50.8%) in the 6 hour-recumbent group and 32 patients (49.2%) in the early ambulation group. The background characteristics and CerebroSpinal Fluid (CSF) findings were not different between the groups. Prevalence of PDPH was 16.9% (overall), 18.2% (6 hours) and 15.6% (early ambulation). There was no statistically significant difference in prevalence, pattern and severity of PDPH between the groups. CONCLUSION: The prevalence and characteristics of PDPH were not different between the 6 hour- recumbence and early ambulation groups.

Comparison of 27-gauge (0.41-mm) Whitacre and Quincke spinal needles with respect to post-dural puncture headache and non-dural puncture headache.

BACKGROUND: The incidence of headache after spinal anaesthesia has varied greatly between studies. We compared the incidence of postoperative headache in general and postdural puncture headache (PDPH) when using 27-gauge (G) (outer diameter 0.41 mm) Quincke and Whitacre spinal needles in ambulatory surgery performed under spinal anaesthesia. METHODS: In a prospective, randomized study, 676 ASA physical status I-II day-case outpatients were given a spinal anaesthetic through either a 27-G (0.41 mm) Quincke or a 27-G (0.41 mm) Whitacre spinal needle. The incidence of any type of postoperative headache was assessed and the type of headache defined using a standardized questionnaire including PDPH criteria. The severity of the headache was defined using a 100-mm visual analogue scale. RESULTS: For the final analysis, 529 patients were available (259 patients in the Quincke group and 270 patients in the Whitacre group). The overall incidence of postoperative headache was 20.0%, but the incidence of true PDPH was very low (1.51%). The incidence of PDPH in the Quincke group was 2.70%, while in the Whitacre group it was only 0.37% (P < 0.05). The overall incidence of non-dural puncture headache was 18.5% and did not differ between the study groups. CONCLUSIONS: True PDPH seldom occurs when a 27-G (0.41 mm) spinal needle is used, although postoperatively a non-specific headache is common. Using the 27-G (0.41 mm) Whitacre spinal needle further reduced the incidence of PDPH. Thus, we recommend routine use of the 27-G (0.41 mm) Whitacre spinal needle when performing spinal anaesthesia.

[Puncture of solid tumors of the liver with large caliber needle guided by ultrasonography. Study of 70 punctures].

Seventy specimens of solid hepatic tumors were obtained for histologic examination with a 18 G (1.2 mm) diameter needle under real-time ultrasound control. Overall sensitivity was 95.6 p. 100 while specificity was 100 p. 100. Distinction between primitive and secondary malignant tumor was possible in 91 p. 100 of cases. Transient hemorrhage at the puncture site occurred in one patient. These results attest to the superiority of guided puncture with a needle of sufficient caliber, thus allowing for correct histologic study. Side effects did not occur more frequently than with fine caliber needles.

[Value of disk puncture in the diagnosis of infectious spondylodiskitis. Apropos of 48 punctures].

The authors report on their experience with discal puncture in the bacteriological diagnosis of 48 infectious spondylodiscites. This technique makes it possible to obtain a bacteriological certitude in 31 cases (65 per cent): Pott's disease (40 per cent) and 12 pyogene spondylodiscites (25 per cent), with 17 punctures remaining negative, including 5 technical failures, the needle not penetrating into the pinched disc. No incident was noted, demonstrating the harmless nature of this method. The authors insist upon the necessity of washing the disc in order to decrease the percentage of failures.

[Central nystagmus writing during the pendular test. Findings on post-punctural symptoms after lumbar puncture (author's transl)].

The central nystagmus writing (ecriture centrale) during the pendular test is characteristically found in cerebral organic or functional lesions. Thirty patients with symptoms following lumbar puncture (L.P.) were investigated with the pendular test. In 46.6% central nystagmus writing was found 3 days after L.P. After subsiding of post L.P. troubles all the nystagmograms became normal. A control group of 30 patients without symptoms after L.P. did not show patholgic variations in the nystagmus writing during the pendular test.

[Diagnosis of bone metastases. Value of the guided puncture and the posterior iliac crest systematic puncture-biopsy].

The results of bone puncture (P) or aspiration biopsy (AB) in a series of 82 patients with skeletal metastases are reported. In 71 patients, AB of the posterior iliac crest was performed systematically, irrespective of the site of the bone lesion and without aiming at a suspicious area. In 11 patients, P or AB were guided by televised fluoroscopy towards an image of bone metastasis. With either method, a diagnosis of metastasis was made in 42/82 patients, i.e. 50%. With the first method, positive results were obtained in 43.7% of the cases; the figure rose to 54% in cases with known primary cancer and abnormal X-ray image and dropped to 36% in cases with abnormal image and no history of cancer, and to 9 p. 100 in cases with normal X-ray films. In all 11 patients had fluoroscopy-guided P or AB, histological examination of the specimens was positive for metastasis.

Ventricle puncture for external CSF drainage and pressure measurement using a modified puncture needle.

A modified needle for external ventricular drainage is presented. Contrary to conventional spinal needles with this instrument the sharp guide can be withdrawn after penetration of the dura, thus, no sharp instrument affects the brain, nor remains within the ventricles in cases of continuous drainage. Furthermore, depth of penetration can be determined preoperatively by means of a set screw also facilitating fixation of the needle. To date, we have used this modified needle in 50 patients for short or long term CSF drainage and for CSF pressure measurements. Trephination was performed with a hand or battery-driven drill. Except for an infection in one case we found no serious complications in our patients. In our opinion, ventricle puncture for external drainage and pressure measurement with this device is a simple and safe method and can be performed on the ward under local anaesthesia.

[Puncture track metastasis after ultrasound-guided fine-needle puncture biopsy. A rare complication?].

Bilaterally enlarged adrenals were diagnosed by ultrasonography in a 57-year-old man with a potentially resectable adenocarcinoma of the lung. Ultrasound-guided fine-needle biopsy of the left adrenal revealed a metastasis, proven cytologically. Chemotherapy was tried but failed to influence tumour growth. Three months later a painful subcutaneous nodule was noted in the area of the previous needle puncture, which on removal proved to be a skin metastasis. The patient died later from the underlying tumour.

[Percutaneous, ultrasound-targeted fine-needle puncture biopsy (liver, pancreas, intestine) and ultrasound-targeted pancreatic duct puncture].

Ultrasonically guided fine-needle aspirations were done in the liver of 42 cases of malignancy established later by autopsy and biopsy. The sensitivity was 95.3%. Only in one case, in a metastasis of renal carcinoma, precise tumour classification was not possible cytologically. Pancreatic malignancies were biopsied in 28 cases with later verified diagnoses at post mortem and biopsy; the sensitivity was 85.7%. One pancreatic head adenocarcinoma tumour classification was not possible cytologically. In 16 cases of gastrointestinal carcinoma verified by operation the sensitivity was 93.8%. In one cirrhotic gastric carcinoma only insufficient cytological material could be aspirated despite several biopsies. There were no false positive results in any puncture. The cytological results in all malignancies (n = 86) agreed in 97.7% with later established histological tumour classifications. Two clinically relevant complications were observed (biliary peritonitis, haemoperitoneum). In 15 percutaneous fine-needle pancreaticographies it has been shown to be an advantage that pancreatic juice can be aspirated prior to contrast medium filling of the pancreatic duct. Hyperinstillation into the organ can thus be prevented. In addition, the pancreatic juice aspirate can be investigated cytochemically. Only part of the patients (indurating changes of the pancreas such as chronic pancreatitis) experienced an unpleasant or painful sensation. For this reason such patients should be given analgesics.

[In vitro and in vivo demonstrations of puncture instruments in the sonographic real time image. 1: Puncture needles].

The article reports on systematic sonographic examination of needles for aspiration biopsy in a waterbath and in an animal model. The in-vitro findings were found to be applicable to the in-vivo situations. Needles can be visualized almost true to construction in horizontal longitudinal view and produce an angle-like reflex at the tip in oblique longitudinal view. Roughening of the needle surface yields an amplification of contrast in the sonographic image. The same effect may be obtained by roughening the intraluminar parts of the needle. This is achieved by the corkscrew turns of the Nordenström needle or by means of stabilized air bubbles in gel form, the latter being interpreted as a kind of contrast substance. Internal inhomogenerization while maintaining a smooth exterior surface leads to contrast augmentation of the needle in the sonographic image without surface-induced traumatization during puncturing.
